[Q] Such variance between wifi speed on laptop and phone, why? - Nexus S Q&A, Help & Troubleshooting

I ran a speedtest on my laptop and then on my phone. Both connected to the same wifi and at the same distance. My laptop got 27 Mbps while my phone only registered 6.5 Mbps. Why such a variance?

Well both Mercedes and Fiat have wheels. But guess which one goes faster on them? It's the same with your laptop and phone.
Transmitted from somewhere in space... from my Nexus S... and Tapatalk.

too many factors play a role
CPU speed
RAM amount
Bus speed
Adaptor type in each device
Power management ...
that to name few

I think this is really good question. To start, I'm admittedly not the most knowledgeable on the subject. But in the process of researching why a pci draft n wireless card was slower than an integrated card, I discovered that there are various versions of each frequency. The variation can be due to power consumption, comparability, hardware placement, and many other things. So perhaps our phones are the same. Hopefully someone more knowledgeable on this topic can correct me or further elaborate.

RAM speed or size rather has a lot to do with it.

Laptop have multiple antenna (MIMO), better reception where as phone have limited antenna might be one of the reason. WiFI chipset also plays a role here.

3G data performance

Hi All
I changed from a SE p1i to a HTC Touch Pro. In terms of phone easiness and functionalities I lost a lot but in terms of HW I though I gained a lot. However I started to realise that although it has HSDPA and HSUPA the internet over 3G was very, very slow. I sent it to repair and come exactly the same. The best speed I can get is 61Kbps DL when 3G provides 384Kbps and HSDPA 7.2Mbps. Since the latency is very very high, I cannot get the complete rendering of a complex page if the http server gives time-out too early. Using the PC with the VPN is a nightmare.
A friend of mine that is a radio engineer in Nokia told me that this is a "well know problem of Windows Mobile that cannot cipher/decipher the 3G radio packets in real time". I searched on the internet and couldn't find nothing however I tried several HTC and Samsung phones with Windows Mobile, on several operators and countries and all are very very slow. And comparing them with the SE pi1 that worked like a clock... until it broke :-D

I think you will find you are getting 61 kiloBYTES per second which equates to 488 Kbps, I use it with VPN and it's great, how are you connecting your PC to your phone, hopefully not via internet connection sharing or it will fail the VPN security check and boot you off quickly
Hi Everyone,
I too was noticing speed issues and they are for sure there. People on these boards have been seeing upto 2Mbit downloads speeds so it can be done. As my sig shows I got 1.7Mbit with 1-2 "H" bars.
I loaded a new radio on mine and that seemed to almost double my bandwidth, I was using the standard .32 radio and was getting around 600 to 700Kbit and then switched to the .28 radio and was getting 1100 to 1300Kbit. Only do your speed tests by tether unless you feel you have a good mobile website to do your testing. I was using www.dslreports.com/mspeed but the results are junk, theirs servers are not able to supply enough bandwidth for a good test.
Secondly I installed a new ROM, specifically I am using NATF's 2.3. This will make the phone way faster in terms of performance. It also allows me to tether via the USB and use my VPN without any problems.
I have an AT&T data card for my laptop (it's a work thing) and I get equal coverage/speed on the fuze as I do on this dedicated device, that is without the radio change that is.
Give the above items a try, the information for making the changes can be found in the ROM development area
Thanks All
Thanks for the feedback guys.
I used GoToMyHelp.com to make the test and provide me the results in both Kbps and KBps... 7.6KBps they said... GPRS speed.
With 3G only the results vary from 17Kbps to 60Kbps, when I turn HSDPA on I always get 61Kbps... looks like the phone cannot handle more than one major WCDMA code with the most robust and slowest modulation code...
But if people reported higher speeds then it means I really have an HW problem and so I have to insist with the service centre... I guess...
Henrique
But...
Although from the comments received looks like the problem is more acute on my device I tried a Samsung with Windos Mobile 6.1 and it is as slow as mine... I think it is too much coincidence.
Does anyone has any information regarding the so called "well known limitation of the cipher/deciphering in real time of windows mobile?
Thanks for any feedback...
Henrique
i get from 800kpb - 1000
never tested upload.
is tehre another test?
I only trust speedtest.net through a hardline tether (not bt) for speed test results. This moves as much processing power as possible from the phone to a full fledged computer, reducing such variables as screen drawing speed, free memory, cpu utilization, etc.
I find the fuze to perform almost exactly in line with my 881u (best speed ive seen on that is just over 2400 down, 900 up) - the only discernable difference is latency, slightly better on 881u (which is to be expected as there isnt ICS running as a proxy in such a situation)
As to the fastest speed you'll see on the device itself, I have not been able to clock over 1700 on speedtest.net running in flash lite 3.1 in opera mobile on my wifi, where i score 5500+ on the computer, so i think testing via phone's browser is not a very good measurement.
I don't know, I just switched my Settings > Phone > Band to GSM to see if it saves substantial battery, opposed to the 3G and even further "H" icon HSxPA I was using before.
The "E" icon GSM-Edge doesn't seem to slow down my Google Maps updates very much.
Thanks
Thank you all for sharing your experience.
The tests I made were using the phone as a modem via USB, so the processing on the phone was at a minimum.
The site I indicated before, GoToMyHelp.com, is used by a Firefox extension I have. After trying several sites this was the one that always gave me the best perceptible match between the browsing experience and the measured figures...
Now comes the hard part to convince the customer services that the phone has problems...
Henrique
I think I have the same problem. I am getting crazy low speeds on G and H, 30Kbit/sec and 60 Kbit/sec respectively. I have tried various tweaks found on the forums, I've flashed a couple of cooked roms and various radios but can't get it any higher. I've tried the SIM in the wifes iphone so I am sure that it's not a problem with that.
Let us know how you get on, are you going to call HTC direct or go through the company you bought it from?

im getting 820kb/s in a suburaban area. It works great. Did you enable HSPDA. AT&T turns HSPDA by default (probobly to save bandwidth). All you have to do is fix it...im not sure how search the forum. I am using DA_G Clean fuze rom and it has it built into the ROM
OMG i just tethered my PC and I got some crazy speeds
And that was the lowest one. It went all the way up to 1900..obviously it flutuates a lot but it is still leveling off around 15k....which is crazy because I only have TWO bars!
this is my home
Its crazy that my phone gets speeds half as fast as my DSL and it only has two bars and im in the suburbs!
i tried iphonespeedtest.com on 1.07 proven and got about 400 at highest
tried it when i used his 1.08 i got 1200 kbps
its sick

Is it possible that while tethered the phone is capable of more data throughput that isn't possible while browsing on the phone? Similar to the problem of encrypted WiFi being slow due to the processor load of encrypting and decrypting data.
From a technical standpoint when you're tethered all the phone does is pass data from the 3G connection to the USB port. The only processing needed is basic lower level networking to re-address the data packets to a new port, thus the processor has a low load and can dedicate more cycles to simply moving data. The phone can focus all of it's power on getting the fastest connection with the 3G tower.
But when you browse on the phone the processor needs to terminate the data packet and unload it into a program. On top of that even more processor power goes towards running the program itself that is using the data. Since the processor is busy multitasking by running a program, terminating data packets, and trying to maintain a connection with the 3G tower, it's more likely to drop packets or lose it's connection.
This would also explain why you lose that weak 3G connection and drop to EDGE when you open a program that has high processor demands.

Wifi Signal Strength

Why is it that the wifi signal strength is better on my laptop than on my phone?
I have noticed this for nearly every device I have owned. The laptop will always seem to catch a better signal than the phone, even though they are both in the same position, same network, etc.
Is there anything I can do to boost the signal range of my phone?
(no I'm not sticking an antenna on it)
Interesting - I notice the complete reverse. My doubleshot has stronger signal to my wifi router and for a longer distance (of about 5 feet in my driveway) then my laptop.

Out of all the different phones I have owned, NONE have been able to catch wifi signals as good as my laptop
As I speak right now, I am connected to the same network with both devices. Laptop shows a good signal, while the phone is showing a poor signal, and even disconnects at times.
Interesting. I guess logic might wanna tell me that a laptop would have a larger/more powerful radio chip, or whatever it is that receives the signal... and that has basically been my experience, my laptop can stray further away from the router. But perhaps it depends on your hardware?

Well, my laptop is about 2 years old and beat up, compiling kernels is killing it.
I wouldn't be surprised if the wifi chip suffered some damage from how many times its overheat and shut off.

I have this same problem, out of all my devices my Doubleshot is the worst at picking up a wifi signal. This includes two other low end Android phones, the Droid Eris, and the Huawei Ascend. On my Ascend I can pick up my neighbors wifi almost anywhere in my apartment, even better than my laptop, but on the Doubleshot I can not pick up the signal at all unless I am outside right next to my neighbors house. I wish there was a fix for this issue. Even at school where the wifi is very strong, I can only pick up a weak signal that disconnects from time to time on my Doubleshot, but my Ascend never had that problem, it always received the signal strong and clear.

My laptop is nearly 4 years old. Runs a Centrino chipset. Maybe that explains the better signal it catches. Either way, I've never seen a phone outperform a laptop in signal strength

lol - you should come by my house. Sometimes (I posted it in a thread a few months ago around here somewhere) I use the doubleshot as a wifi bridge to my router to make up for the inadequacies of my laptop wifi abilities, or for my desktop that has no other means of internet connectivity.
It seems I represent a minority (of one!) in this... i dunno. I've been excited about how well it works out, and am quite surprised (astonished even!) to find everyone else singing a different tune.

Yea, seems like you're the only one. By the way, if your laptop is overheating from compiling, you're doing something wrong. No laptop should overheat, even under full load, unless you have blocked vents, or you're overclocked.
Lol, unless it's choked with dust, has no compound between the processor and heatsink, the fan doesn't work and it relies on an external cooling pad for all of it's cooling air circulation.
Half the usb ports are burnt out and no longer function and the speakers stopped working a year ago. Since the audio out jack has stopped functioning.
I'm pretty impressed with the fact that it even still turns on, let alone being able to actually do anything with it, but, I'm hoping to get a full blown linux install on the doubleshot and thereby circumvent ever having to purchase a real computer again.
I'd grab another laptop, but, i'd rather invest my limited tech funds into android hardware and write off real computers entirely, and given the capabilities of the doubleshot and future android devices on out this is no pipe dream - the only thing between me and realizing that goal is the knowledge to make it happen, a gap that shrinks daily.

[Q] Boost Wifi Speed?

I've spent days searching the internet, google, xda, several different droid forums, but I can't find a real answer to my issue...
The speed test results on my tablet are absolutely horrible. Is there any way to actually increase the DL speed at all?
I've got a pretty cheap tablet. It's a 7"Craig model CMP741e running ICS 4.0.3 AnTuTu rating 4217 (CVS Cyber Monday special).
Connectivity is a non-issue. I was connecting to my home wifi network at 65Mbps. After fiddling with my router (FiOS supplied ActionTec) and changing my broadcast channel as well as disabling "compatibility mode" to run in n only, I was able to boost that connection to 150Mbps (signal strength dropped slightly from about -45dbi to about -50dbi). Streaming media files via LAN improved, but there was no impact whatsoever on actual internet performance.
On my wireless PC I'm getting about 27M down/ 5M up acc. to Speedtest.net. While sitting right beside that computer I test my tablet and the best I'm getting is an average of about 3-4M down (peak about 12M) and a steady 5M up.
An suggestions for squeezing some more speed out of my tablet? Internet surfing is brutally slow. I get TONS of lag and ANR errors. I've tried a couple different browsers (ICS stock browser, dolphin, and chrome) but the results are always the same. I also get a ton of ANRs in the Play Store and in a lot of games.
The tablet came factory rooted, but I haven't experimented yet with any custom ROMs or MODs. I'm a Droid noob, still getting my feet wet.

Seeing that my home connection is 5Mbs down 1Mbs up and its pretty fast. (e.g. HD netflix, facebook in 2 seconds, and good gaming) I'm going to say that your low-cost tablet simply doesn't have the computing power to run all the javascript, render images, and all that rich web content stuff with any reasonable amount of speed.
I used to own a cheap no-name A13 tablet with very similar specs and it was very slow for browsing even though things like netflix worked reasonably well. But now I have a nexus 7 and everything is great.

For the record, I wasn't lying. My head's spinning from all of the different articles/ threads/ websites I've been reading trying to figure this out. I've found a bunch of different ways to improve wifi range/connection speed, but hadn't found any way to improve internet speed. I'll look up Zeps now.
I completely agree that the vast majority of the time limits are imposed more by inferior software than the hardware itself. This thing has a decent (1.3G) processor and RAM (!G) that's why I figured it should be capable of better performance.
If you decide to use a custom rom like bbrad just suggested look for allwinner a10 roms. Basically your device is a clone of the allwinner a10 base model. If you search around there are tons of these tablets all virtually identical but with different brand names.
@aftermath If I decide to go with a custom ROM I'll keep that advice in mind and look for something A10 specific. For now I'm just trying to figure out how to get the best performance possible out of the stock ROM.
I found the OP for Zep's Supercharger... there sure is a lot of information to digest there, and I'm short on time ATM. I will definitely look into it more tonight after I get my son to bed.
As far as Wifi Fixer, I had run across that in some of my previous searches. It looks like it's more about connectivity than speed. As I stated, connectivity is not an issue. I'm using my tablet at home and have an excellent signal that never drops.

As I said above, I just want to tweak the max possible performance out of my stock ROM before I start messing around with flashing customs. Android is new to me, so I'm going in small steps right now. I'm not in a position to replace my tablet if I brick it.

You should try WiFi Fixer, that's exactly what the app is designed for. Whenever your signal gets weak/ dropped it should reconnect quickly (and could possibly cut down or eliminate the drops altogether). Try it out, hope it helps.
There are tons of threads about improving wifi connection... This thread is about improving internet connection speeds once you already have a good wifi connection.
SetDNS
After poking around some more i ran across the Set DNS app. It seems to have helped quite a bit. Over the last couple hours I've been periodically running speed tests through Dolphin and the stock ICS browser in clusters of 3-5 tests at a time. My results have improved to a pretty steady 11-12M down (from 3-4M) with occasional scores as high as 24M, and peaks pushing 30M (my full network speed). Still haven't really played with the tablet to see how it effects overall performance, but it seems like a pretty good start.

Nexus 5 max wifi speed?

What's the theorical max speed the Nexus 5 can reach while using wifi? I recently upgraded my wifi speed to 100 mbs but I was shocked to see that the maximum speed that speed test on the Nexus shows is 50 mbps, all speedtest apps available on the store max at 50, is 50 mbps the maximum speed for phones right now??
Sent from my Nexus 5 using Tapatalk
150Mbps is the max theoretical.
It's a 1x1 radio so 75Mbps x 2 (40Mhz).
This is more likely in the 5Ghz range instead of the 2.4Ghz one.

Just to make sure it's not being overlooked... i'm HOPING you're not saying that you upgraded your wireless router and are expecting to have incredibly fast web browsing, but your internet connection is still 50Mbps....

router might be limited to 50 mbps
Anandtech clocked it at an average 136Mbps and had some interesting things to say about the WiFi antenna.
It’s interesting to me that both the Note 3 and Nexus 5 pack the same combo, and end up having just about the same throughput, an average of 135 Mbps when attached with the best MCS, with very brief spikes to just below 300 Mbps. Oddly enough one thing I noticed is that touch input seems to be blocked entirely on the Nexus 5 until iPerf is quit. I’m not sure what’s going on here when the WiFi link is completely saturated, but it seems that touch response becomes very slow. I have no issues with range or connection stability on the Nexus 5, and I’ll also note that the device doesn’t antenna share, but rather has a discrete antenna for WLAN/BT.

Wow. Actually 300Mbps from a Nexus 5? What does your Link speed show for your SSID? I don't think I've seen my Nexus 5 with a Link speed over 150Mbps, and this is on a 5GHz Access Point that my notebook connects to at 300Mbps.

Yes, I double checked, and no I didn't just just upgraded my router, previously I had 30 mbps (theorically) and now I have 100 mbps (theorically) , I upgraded my internet plan and I got a new modem/router (the company sent the modem, otherwise I would have not been able to use the new speed) , I did a couple of tests with my laptop and with my phone, I sat next to the router and I got around 80 mbps with the laptop and around 50 mbps with my phone, a pretty big difference

Haven't heard of that bug. URL?
I just ran speedtest on my Comcast Business line ... it's suppose to be a 50/24mbps line. I got 56.10 down on the first try and 58.9 on the second. I don't think the N5 or Android are the issue with this fellows tests.
I've recently upgraded to 120Mbps and can't get higher than 60Mbps on either my Nexus 5 or 7 (2013) but my Macbook Pro reaches 120Mbps no problem. All on the same router and at 5Ghz (not tested at the same time, I should add!) so I don't know what's going on.

150Mbps is the max theoretical.
It's a 1x1 radio so 75Mbps x 2 (40Mhz).
This is more likely in the 5Ghz range instead of the 2.4Ghz one.

what do you mean with "it's a 1x1 radio"? If I have a router which has both 2.4 ghz and 5 ghz, how does it decide which band will it work with?

The WIFI chip, because of size constraints was limited to how many streams it can handle since it does other duties too (I think Bluetooth and maybe others). The older phones (Nexus 4 and others) also had 1x1 spatial streams but were limited to 20mhz so that's why their max was 75Mbps (or some 72Mbps which some routers will show). The Nexus 5 has a 40mhz chip so it can link at faster rates. Using iPerf I think doesn' send TCP ACKs so that's why they were able to get 136Mbps which is close to the theoretical 150Mbps (or 144Mbps). In the real world however you wont get anything close to that as the internet works on TCP so it has to ACKnowledge every transmission which slows down reception of new data.
1x1 is relating to the spatial streams that a chip can handle..
In order to send faster speeds the device sends and receives streams at the same time. This is why new routers have 3 physical antennas, each connected to a radio (those are 3x3 ones).
In the N spec, each radio can send at a max of 75Mbps using 20Mhz of bandwidth. When you double that to 40Mhz you get 150Mbps. This is why 3x3 routers can do 450Mbps (vs 300Mbps).
The AC routers use the same layout (of 3x3) but because of their better tech (encoding, compression and such) they can put more information within the same bandwidth (20, 40Mhz) and they can use more of it as well since 802.11AC is in the 5Ghz range. They can then use 80Mhz channels as well.
So for AC per spatial stream is about 86Mbps per 20mhz.
So for AC you get 3x3 x 80mhz = 1.3Gbps (1.286Gbps) or only 600Mbps for 40mhz wide channel.

There's a chart on that page which breaks it down a bit more as well as more info.
-------------------------
As for which it decides to use that depends on a few things.
- If you have the same SSID/Password on both then it will use the stronger signal
- IF you have different ones then it will use whichever you specify till it can't anymore then it will jump onto the next known connection (that is if you have both saved)
- If you only specify 1 frequency to use then it will use that

Thanks for all the info, I have to reread it because I didn't understand all of it hahaha, what do you mean with if they have the same password? you mean the router and the modem?

Your 2.4Ghz and 5Ghz frequencies on the router can have 2 different SSIDs or the same. Most people use different ones as a way to identify them but also doesn't allow roaming between them since the device will see it as a separate network.

I did the "quick setup" and i'm completely sure I just set up a password , so I should have only "one network" I did a test with my nexus 5 and set it to receive only 5 ghz signals, and it didn't find my network, then I set it to search just for 2.4 ghz networks and it found mine, I'm guessing that means only 2.4 ghz is working? I'll attach a screenshot of the setup of my modem/router , since there are THICK walls on my apartment , 2.4 ghz would be ideal for me right since it can penetrate objects better , the situation with me is that my walls are very thick but I'm relatively close to the modem/router, around 20 meters I would say.
I'm really desperate, I don't know what to do anymore, I currently have a Router/Modem (a router that includes a modem) I was thinking of buying a new and good router but how would I connect it to the Router/Modem , it doesn't have a WAN port, only LAN ports or maybe I should upgrade my Modem/Router , what would you recommend? To have a Router/Modem or a Modem + a Router? I'm under the impression that Routers/Modem (Router with modem included) don't have the best signal strength , since the antennas are on the inside, unlike a modem like the Asus RT-AC68U which has three antennas on the outside! :laugh:
To clarify, speedtest (like speedtest.net) measures your internet speed which is controlled mostly in part by your ISP. Typically your internal network speeds (Wifi or hard wired) are much greater then your ISP speeds. Your Wifi connection speeds only matter for transferring files across your own network assuming your Wifi connection is faster than your ISP (which it likely is).
The Nexus 5 supports Dual-band Wi-Fi (2.4G/5G) 802.11 a/b/g/n/ac. My home network has a 5Ghz N SSID running at 450mbps and the Nexus claims to connect at that speed, however my Comcast internet is 25mbps so an app like speedtest shows 25mbps. I havent tested to confirm my Nexus can pull 450mbps across the network but i could try it.
Again, what really matters is your internet speed and that your router is at least that fast. Most home internet is well below 100mbps on average and even dirt cheap N routers can hit 150mbps and up. Hardware wise the Nexus can connect to N 2.4/5Ghz and AC 2.4/5Ghz, so id imagine it should be fine for a long time.
I'm under the impression that Modem/Routers (Modem with routers included) don't have the best signal strength , since the antennas are on the inside, unlike a modem like the Asus RT-AC68U which has three antennas on the outside! :laugh:

I have the ASUS RT-N65U which has no external antenna and i get a signal in my apt complexes parking lot through about 3 cinder block walls at a distance of about 50-100 yards. Granted at that point its a weak signal but i cant imagine it having an issue in anything other then a mansion. Best router ive ever owned, highly recommend Asus.

[Q] Z3 802.11 AC speeds?

Have anyone tested the Z3 with 802.11 ac Wifi? What speeds are you getting?
I'm getting 40 mbits with the n standard and i'm considering upgrading to ac if there is a decent improvement.
Thanks,
//waxxan

I'm getting around 433 Mbps and say excellent strength and 293 and it says Good strength
i'm using a Netgear r8000
You will get 433 Max "link speed" as this is a single antenna chipset, though actual throughput will be lower.
Also go an R8000 here free from a Netgear beta test, great router. I get 207 Mbits/s (~25 MB/s) one floor below the router. I tested using my NAS as the test server.
Get the R7500 its more advanced (despite the naming convention) in the sense that it has MU-MIMO meaning multiple devices can be part of a link rotation compared to a regular unit where the router rotates between individual devices. The S801 chipset in the Z3 supports MU-MIMO.
The R7500 has a Snapdragon 8064 dual core 1.4Ghz (Cortex A15) vs the the R8000 which has an older Cortex A9 at 1Ghz. The R7500 will be 70+% faster and run cooler 28nm vs 40nm CPU. I doubt you will notice any difference in regular use though lol.
Thanks thanks for the replys!
I have been considering the ASUS RT-AC87U AC2400, but it might be a bit overkill.
It's twice as expensive as the r7500. I just want a fast and stable connection.
I kind of want to use the flaps as little as possible, to keep it waterproof.
So i was thinking of doing all data transfer through wifi and charge it with the magnetic charger.
The Asus AC-87U uses a slower and hotter running ARM Cortex A9 chip when compared to the coooler running and much faster per mhz ARM Cortex A15 based Snapdragon in the Netgear R7500. The rest of the tech is similar as both use Quantenna tech.
The Netgear R7500 is better than the Asus AC87U, previous bad reviews were before latest updates starting in November. Updated reviews say its very good.
There a few complaints of overheating issues with the AC-87U causing decreased performance occasionally.
Both cost about the same, the Netgear R7500 ~$250 and the Asus RT-87U is ~$260-270
T-Mobile gave me a Asus AC-68u and I've been very happy with it's performance.
I can't speak for transfer speeds as I haven't really tested it. But it easily reaches the entire house, all the way to the back of the yard and to the end of the driveway. (The router is in the basement)
I could stream multiple movies from my pc to multiple TV's throughout the house using chromecasts without a hiccup.
Completely destroys the little Linksys Wireless-N router we had before hand that struggled to get signal to the other side of the house.
Maxes out my internet connection @ 110MB/s down and 30MB/s up
I use the T-Mobile Asus RT-AC68u as well. Free for US customers. I get the same link speeds as above (433 with great signal). It also helped tremendously with the Remote Play feature as I was previously using a 2.4 Ghz router (basically unplayable).
Thanks for all the replys. I actually went and got a r7500, got a pretty good deal.
My z3 is maxing out my isp cap at 100/20. But the data transfer from my computer is still quite slow, about 10 Mbit. Tested with xperia wifi connectivity and es file explorer. Any advice to max out the data transfer?
Update the router? What is the firmware version of the router?
I updated to latest firmware during the initial setup.
However, I am getting 100 Mbit over wifi with Tptest on the z3, but not when download downloading files.

Dumb question, but how is the PC connected to the network?
Yeah that's a good question!
So I tested the Z3 upload/download to my Netgear ReadyNAS104 which is connected to the R8000 by Gigabit Ethernet, I get ~25-26 MB/s (207 Mbits/s).
Are you doing WiFi to LAN or WiFi to Wifi? WiFi to Wifi can be slower espescially depending on the WiFi card of the other device and distance from router.
Best way is to test is WiFi to LAN. Like a NAS or HDD connected to the router directly.
I tested near and one floor below the router with same result. The R7500 should give you a similar result. Use a test app called "WiFi Speed Test" or something similar or just direct transfer to and from phone.
The PC is connected over LAN 1Gbps.
I downloaded the wifi speed test app, and the server version for my PC. Test gave good results, about 180-205 Mbits both up and down.
I also changed the test file size in the app to 1GB, and it worked great. I followed the transfer speed in windows taskmanager networking tab, and i can see that it is using about 20% of a 1Gbps.
BUT!
How do get these speeds in actual file transfers? Both remote share and a ftp client on the z3 only uses about 1.5-2% of the 1Gbps.

What size files are you transferring? The bottleneck becomes your hard-drive/ssd in your computer, and the flash in your phone. Especially if you're transferring smaller files.
Im testing with one single file, circa 1Gb. Copying to the internal memory on the phone. BUt since the WiFi speedtest app can generate these speeds, also with 1gb file size, from the same computer with ssd. Transfers from windows and via ftp should have the same speed, but it doesn't.
Packet size etc can have an impact on transfer rates.

Can I change this in windows? Also, can I see what the packet size is for the WiFi speedtest app? I assume it's "message block size" which is 4096 bytes
Ok, I did some more reading and testing.
I found this information
"Internet Explorer and Windows Explorer have a static buffer size of 4096 bytes that can't be changed, in comparison to that Filezilla has a buffer size of 256 KB."
I thought I already tried with ftp, since I downloaded a ftp server on the z3, But I used windows explorer to connect to it, thus the buffer size limit, I guess.
So I downloaded Filezilla and tested the transferspeeds. about 15-20 MB/s, so thats good.
Now, to the problem. FTP apps dont seem to have write access to the SD card.
Is rooting the only solution for this?
Yes, root or Android 5.0 since that adds the access back.
