So if you're like me you flash the latest radio that hits the streets and go directly to http://www.dslreports.com/mspeed?jisok=1&more=1 to download a megabyte and see how much faster your phone goes.
Stop that.
For the past few months, consistently during American business hours, I have been getting < 500Kbs/s on the phone from dslreports.com/mspeed but would get >1Mbs after 6pm. I was wondering if it was AT&T or dslreports.com who had poorer service during peak hours or both companies so eventually I did the mobile speedtest on my office computer a have a 5Mbit connection. Guess what, I got on multiple occasions with no exception < 500Kb/s on the computer which got a 4Mbs speed test from Speakeasy.net an instant later. Dslreports's mspeed thing was good while it lasted but until they get a better connection or figure out a better mobile speedtest thing to redirect you to other servers you can't count on them.
If you want to do an accurate speed test, tether your computer or laptop to your phone either with USB or wmwifirouter (not bluetooth) and go to http://speakeasy.net/speedtest/ and fire up a few tests from different locations. You could go there on your phone if you have Flash but the test interface may possibly eat up too much processing power to handle all the incoming bandwidth to produce an accurate result. So tether to a proper speedtest site (I recommend Speakeasy's). Plus you get upstream. Also if you're comparing radios and take this seriously make sure your phone is positioned almost exactly the same between flashes and tests. And the fewer bars you have the less confident you should be in the accuracy of the tests relative to each other.
If one of you would like, I've got a no-bandwidth-cap shell account on a machine of a reliable ISP and would be willing to host a megabyte speedtest if you can code the thing to time the download and do the math -- contact me.

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...

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.
I get crappy speeds via the WiFi hotspot. For example, when I am in a good 4G zone, I get 2-3Mb download speeds on the Evo itself but my laptop or iPad connected via hotspot will get between 200-400Kb downloads. Same problem when I'm in 3G.
*bump*
Any help would be appreciated.
200-400 kilobits or kilobytes.... if its kilobytes, then that is normal download speed as statedfor your 4g connecting.
Kbits.
If I get 2-3M download speeds on the phone, why would another device connected by wifi to that same phone not get at least similar download speeds? If I get 2M on the phone and 1.6 to 1.8M on the iPad or laptop connected to the phone's hotspot, I'm happy. But getting 10% of the download speeds doesn't make sense. The Evo clearly has a great signal. Why would it not be able to pass it along to other devices by wifi since Sprint's Hotspot is designed (and marketed as being able) to do that?
--- Edited, I can't read apparently ---
Have you tried different channels on the wifi tether? Might be interference? Are you running at full 54mbit on the client? Interference would easily drop the speed down to 11 or lower, and absolutely KILL your speeds
Try firing up osmonitor (is cmdline top available?) and see if something is maxing the CPU. Since most of the routing is done with the built-in Linux routing and iptables, I don't think that would cause it, but CPU usage or interference would definitely kill it.
I get 3000kbits/s or 3Mbits/s on the phone and I get 200-400kbits/s via WiFi hotspot on my computer. I am getting about 10% of the bandwidth via the WiFi hotspot than I get on the phone itself or even on the laptop when tethered via USB.
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.

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.
Hello All,
As the title says. Anyone experiencing slow WiFi download speeds? I get 50~100Mbps down and 800+Mbps up. I have an iPhone 12 Pro Max next to me and it's getting 500+ on UP and DOWN speeds. All things point to a Samsung issue, the rest of the WiFi devices are doing much better on 2.4ghz and 5ghz.
I've test various settings on the router itself. Different channels, Channel bandwidth (40,80,160) , and the issue still persists.
My router is an ASUS RT-AX82U and it's about ~10 ft from phone.
Any feedback would help. Seems like Samsung is struggling with WiFi 6 issues. My Tab S7+ can't even connect to the new WiFi 6.

Updated my router a couple weeks ago to TP-Link WiFi 6e, I only use WiFi 6 cause only a couple devices support the 6 ghz band. But I'm getting between 800-890 mbps down consistently. On a U1 S22 Ultra. It's about the same on the 6ghz band as well.

My S22u connects to a Nighthawk AX5700 wifi6 router (Costco model) at 1.2 - 2.4 Gbps depending on how close I am to my router. I get 500up/500down pretty much everywhere in my house (this equates to my Fios internet speed) utilizing 160Mhz channel width. This is with no changes to my S22u wifi setup out of the box.
Also of interest is the type of phone case, if any, you are using.
I'm getting 339Mbps down 23Mbps up on Speed Test. My internal is 650Mbps, I don't have a WiFi 6 router.
Seems like this is an issue. https://us.community.samsung.com/t5/Galaxy-S22/S22-ultra-5ghz-wifi-issue/td-p/2204964

At first I thought it was the router but I did replace the ASUS with a Linksys Wifi 6E and same issue with phone. Also distance and number of devices connected doesn't matter I've tried just 1 phone 1 router and literally standing next to it same issue.

Ok good info. Is your backhaul from the mesh APs to your router via wired or wireless connection?
Not sure if you have installed any wifi debug/info apps? I use Net Analyzer and it would be great to see a screen shot of your 5G spectrum in graph form like below.
I have a Verizon FiOS symmetrical Gigabit link. My PC gets 900+ on both uploads and downloads over ethernet, and around 500 by 500 on wifi. My S22 Ultra Qualcomm version seems to max out at 360 to 400 down and 60 to 150 up. I have a Ubiquity Dream machine pro with their wifi 6 LR Access point (in a one-bedroom apartment, around 8 feet from the Wireless AP).
The speed test were run within a minute of each other, using the same remote server.
I wanted to remove wifi as a variable, so I tested a USB C to ethernet adapter, yet download speeds are still limited to 300, and upload jumped to 700 Mbps.
Does the S22 Ultra have some bandwidth restrictions or other issues?
I have screenshots if that helps.
Curious if anyone else has tested their S22 Ulta network speed using a USB to ethernet adapter.
Thank you,
Ryan
are u on wpa2-aes?
I have Fios 500 up/down and I get 545 up and 500 down on my S22u. Check your wifi connection speed on your phone to ensure its connected to your router at a speed that is greater or equal to your internet speed.
Just got 381/23.3 Mbps down/up (WiFi); and my Tab S7 is getting 355/22.3 Mbps down/up (WiFi). Both were about three feet away from the router.
As a comparison, my Dell desktop is getting 476/22.4 Mbps down/up (wired).
I consistently at or near the bandwidth I am paying for. I have Google Nest WiFi with three mesh points. I am paying for 400/20 Mbps down/up.

So again, check your wifi connection speed on your phone to ensure its connected to your router at a speed that is greater or equal to your internet speed. Settings->Connections->Wifi->Your SSID->gear.
This will show you the connection speed between your phone and the router. If this is less than your internet speed then you will never get what you paid for. Most wifi speed issues are within the home wifi network, not the phone.
Btw, my phone connects to my home wifi6 network between 1.2 -2.4Gbps so achieving the full 500 up/down speed I'm paying for to the internet is not an issue.

I also have a UDMP router and Unifi U6 AP. On speedtests (not WiFi link speed), My S22U Snapdragon can reach 1.9 Gbps on 160MHz channel width and 900 Mbps on 80MHz channel width. Download/upload speeds are the same for me.
There are no bandwidth restrictions. The problem is your Wi-Fi setup. Make sure you're using 80MHz channel width and a relatively clean Wi-Fi channel (check with WiFi Analyzer app to find cleanest channel). Also make sure to test in the same room as AP with a clear line of sight to see maximum throughput.
