Steaming HD over wireless network lag

Hi guys,
I have been trying to watch HD video files from my media server over my wireless network on my Note 10.1. However, no matter what I use it just lags and stutters. The files play when put on an SD card which means it is related to the buffer speed.
Surely it isn't too much to ask for the note 10.1 to be able to stream a film wirelessly stutter free or am I expecting too much?
Thanks

How congested is your network, and what frequency band? Also, which player are you using?
I switched to 5GHz "N" WiFi (as the 2.4GHz band at home and work is just a huge mess) and am using the "Dice" (and "MX") players and I can stream MPEG/H.264 videos with no interruptions.
One thing to consider is if the initial connection is judged to be fast by the player, it might decide to not need to buffer that much, which leads to slowdowns once the WiFi thruput decreases.

It is on the 5Ghz band on my new BT Homehub router. Would I be better buying a separate wireless router and connect it up?
The only other things which use wireless are 2 mobile phones. The computers are wired.
Currently I have shows working okay for 11 minutes and then they slow and stutter. Never to work again! Very frustrating unfortunately.

There IS the possibility your media server might be an issue- I have a couple of PogoPlugs that I use for this purpose, and they work well both over 2.4GHz and 5GHz.

I have the HP MediaSmart Server. It is connected via a wired gigabyte connection.
Unsure of how to solve this issue. Streaming to a laptop over wifi is no problem.

Are you running a stock kernel on your GNote? What's the effective bitrate of your movies? Are there any QoS settings in your router?

Yes mate my note is running stock. As for QoS, I am unsure. Quite sure the router is basic to be honest but given that I can stream to laptops it leads me to believe that my tablet is the problem.

Kinda/sorta- the reason I'd asked about being stock or not is that I suspect the WiFi in stock devices isn't optimized for streaming but more for surfing (there's a slight difference in the way packets are handled between those two modes) and I've got a kernel that uses a different TCP "backoff" setup and I'd wanted you to try that.

Have you check your wifi signal with an app like Wifi Analyzer to see if you have other devices crowding the channel that you are trying to use. You may be amazed at what you find.

He's on 5GHz, though- while not impossible, it's unlikely it's a channel-crowding issue.

You have to start some place and this would be my first step in trouble shooting any WiFi issue.
Also........ The higher the frequency of a wireless signal, the shorter its range. Thus, 2.4 GHz networks cover a substantially larger range than 5 GHz wireless networks. In particular, the higher frequency wireless signals of 5 GHz networks do not penetrate solid objects nearly as well as do 2.4 GHz signals so 5 GHz hardware offers a few advantages over 2.4 GHz hardware, but in practice, 2.4 GHz is usually the better choice for home and other wireless local networks
Higher frequency networks are not necessarily superior to lower frequency ones, its a fact.

Well the lower-penetration disadvantage of 5GHz is offset greatly by the higher possible bandwidth and lower interference rates- but if his 5GHz network is 802.11n, perhaps he's got a mesh setup going on that can help alleviate some of that (the OP's gotta love how we're talking about him like he's not right here, too ).
But I can easily help OP determine if the issue is band-related thruput- can he download one of the movie files? Do that while timing the download, and see what kind of effective bitrate he's getting (I'd also suggest running the Ookla "SpeedTest" app).

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??

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.

but there are not that many servers or routers that will give you this.
i test off a gig server for speedtest, not sure what FCC uses.
i have gig fiber and a netgear R7000 router

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.

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

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 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] Wifi 5Ghz problem

The Wifi Range on the 5Ghz is really low. WTF! The signal does not hold just out of the room from where the wifi router is kept. I tested it with wifi analyzer and the signal just drops. To double check I used my Samsung Tablet with 5Ghz band and Laptop with 5Ghz card at the same distance. They work just fine and get full range and speed. 2.4Ghz works okay. But there is lot of congestion in my apartment. So I use 5Ghz. The router is Asus N66U Dual band.
1) I have latest router firmware.
2) WPA2- Personal
3) 5Ghz is running on 20/40Mhz bandwidth in the 157-161 channel.
4) Running stock rooted CM11S.

You are comparing your phone with 2 devices that have at least twice the length of wifi antennas inside their chassis. What would you expect, seriously?

I have the same issue. Funny thing is the lower band 5ghz channels work better but still not like the SGS4 did. I notice the signal drops quick and the disconnects... It's messed up.

echo this... very non consistent 5ghz range as compared to both a nexus 5, galaxy s4 where both of those phones in my house have consistent 5g wireless connectivity.
i had to drop down to 2.4ghz to maintain connection on the OPO

I have zero problems with my two devices connecting to my 5gHz network at home. Always connects, always consistent.

Wifi showing 1Mbps connection speed

Hello guys,
I just received my Motorola Photon Q mobile. Asked Cornholio to do the SIM mod.
Tested my new phone yesterday with carbonROM . Well I Must say all looks good except wifi.
Wifi speed is showing me 1Mbps
My old xperia mini pro is showing me someting around 70Mbps. My wife has got new mobile too ( Lenovo Vibe X2 ) and she has 150Mbps.
Even her old Iphone 4S is showing her 70Mbps or so.
So it looks like there is some problem with my new phone.
My router is Netgear JWNR2000V2.
Do you guys have some experience with this ?
Thanks a lot

Is it actually slow?
You won't get 150 or even 70 mbps as the phone doesn't do 802.11n IIRC. G is limited to 54mbps, and that is 'ideal'. Also the phone doesn't do the 5ghz band, so you are limited to 2.4ghz.
Unless you wifi speeds are actually slow, who cares what it says it is connected at.

That's not completely right.
It does 802.11n but not the 5GHz band.
It also has only one WLAN antenna, so the speed is limited.
Looking in OpenWRT it shows for my PQ:
RX Rate -> 72.2 Mbit/s, MCS 7, 20MHz
TX Rate -> 65.0 Mbit/s, MCS 7, 20MHz
MCS Index -> http://mcsindex.com/
Btw. it is actually better using 802.11n over 802.11g.
So don't disable 802.11n in your router, consider to disable 802.11b instead.

Well yeah it is slow.
I was not able to connect or load the Google store yesterday on my new Photon Q.
But I must say it is connected. I saw some threads whre ppl were complaining that wifi is connected and disconnected after some time. I do not have this. I have just this connection speed is 1Mbps So watching youtube videos or surfing web on the phone through wifi is not possible at the moment
So I am oging to do some testing today. Hope I will find the problem.

I was never able to get my N network to connect... but I may have been forcing it to 5ghz, which explains why it wouldn't have connected.
I haven't used my Q in a year or so personally, so this was all from memory. Either way, the hardware is 3 years old at this point, so the newest wifi tech is a bit beyond its manufacture date.

@arrrghhh, sadly I cannot disable 802.11g in OpenWRT with my router (a driver limitation I guess) so I cannot test it.
There were also some limitations on wether it connects and if it is stable (a wireless setting "preamble" [short/long] caused me random crashes).
@Jovzin, if I remember right, there have been reports that a defective WiFi antenna might be the problem.
Though, I'm not sure where and how the antenna is connected. I only know that there is a "special plastic" within the phone, which replaces the antenna.

Did test with my router: When I was about 5 meters away I got 26Mbps. I got closer to router and it drops back to 1-2 Mbps. So really do not know what is happening crap.

What is your router configured to broadcast? Have you tried changing any of the settings? Are you sure the hardware is OK - did you test it before the SIM modification?

@Jovzin, it might help, yes. (Shipping costs are pretty high.)
But first you should open your PQ and take a look.
Maybe CornholioGSM just forgot to attach it correctly and you don't need to replace anything.
Also, please answer to arrrghhhs question.

Are you sure it isn't a power saving function? Try downloading something in the background and then checking the connection speed.
My droid 4 also connects at 1Mbps when the connection is idle. Laptop wireless adapters also commonly do this to save power - they show their unthrottled speed on the wireless panel but you can see it connecting at 1mbps when idle on both the router and 3rd party wireless utils.

Hello some good news.
I did a factory reset.
And now somehow it is working. And I am sure taht I have uncheckd that battery saver for wifi.
But when the phone is idle it is 1Mbps. When I am downloading somethign from store it is 65Mbps. Hmm there is some build in saver ? Which is different than this power saver wifi which I can tick in wifi options ?
Anyway I am happy that somehow it is working
Thanks for help guys
If I may one more question.
It is possible to watch HD youtube videos on PQ ? Cause in youtube app I see only 360p Was hoping that there will be option for 720 at least...

If you enabled 40mhz channel width on the router (you're using 20mhz now), you could double the 65mbps to 130mbps, but this only really works well if you're using 5ghz channel, or have a very quiet 2.4ghz channel, otherwise you're subjected to more interference.

Correct.
In 2.4GHz (what the PQ can) it is contraproductive to use 40MHz channel.
It even can be slowed down in a "noisy" environment (I gave it already up).
Also, this is ruthless to your neighbours, so don't.
In 5GHz it is only usable if you can use more than just a few channels.
Even then, it is obvious that most devices are 2.4 GHz and just "a few" can 5GHz (the PQ cannot).
So it actually is not a problem to use 40MHz channel in 5GHz. In future this might change.

Question S22 Ultra (US Version) slow WiFi speeds

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

Spectrum 400/20. I get 478/23 from a wired connection.

329 Mbps down, 16.1 Mbps up @ 5 GHz on a 300/15 plan

Paying for 1 gig UP and DOWN. Ethernet PC I get ~900 UP/DOWN. Wifi on an iPhone 12 Pro Max I get ~500+ UP/DOWN. Other laptops I get similar numbers as the iPhone.
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.

bounddyy & gernerttl can you both:
1. Post a screen shot of your connection speed next to your router like pic below.
2. Confirm you are on the latest version of ur routers firmware.

My current connection. I'm less than 4 ft. from my router.
I have a Google Nest WiFi with three mesh APs. Google automatically updates, so mine has the latest firmware.
The Google Nest WiFi is not WiFi 6e.

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.

866 Mbps connection to my router, Google WiFi Nest is not WiFi 6. Even if it was WiFi 6, I won't get faster than what my ISP provides, which is 400/20 Mbps.
P. S. I have the Verizon S22 Ultra.

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.
