SGS2 and WiFi 802.11n - Galaxy S II General

I see this phone is WiFi compliance with 802.11 n but when I connect it to my WiFi router (which is set to use N only on H-40Mhz - showing 130Mbps rate) the phone shows 64Mbps only , why is it so low ?
For instant my Vaio laptop connected to the same router shows me a rate of 150Mbps .

the actual data rate will always be lower, if you have say virgin at 20 Mbps, what's the point of having a wireless speed any faster than that?

It's important for streaming HD content from phone to TV via DLNA , so a good bandwidth is required for this .
PS> If is not important to you or you don't understand something why do you bother to reply ?

I never thought to check this before but my phone is only showing up as 39mbps over 802.11n

I think it may be because although it is N compliant it only has one physical antenna and full N speed requires twin antenna's

Correct, the SGS2 has only one antenna and can therefore only transmit/receive one spatial stream simultaneously. Since it also appears to only support 20Mhz channel width it can only reach a maximum of 65Mbps. Your 130Mbps router has two transmit/receive antennas for 2 x 65 = 130. And even though it's running at a channel-width of 40Mhz (p.s., this is not advisable if your environment happens to be filled with other networks - it impacts on both your WiFi performance and theirs) this doesn't affect the SGS2 as it can only run at 20Mhz.
Edit: Here's a list of 802.11n speeds, with the number of antennas required: http://en.wikipedia.org/wiki/802.11n#Data_rates

I am able to stream HD videos from my phone using DLNA on 802.11g at a max speed of 54Mbps, so 802.11n is not required to stream HD video via DLNA

Thanks @hazzamon that explains why I have only a 65Mbps connection, tough the Vaio laptop shows 150 Mbps (do you think it has more internal antennas) ?
@achillies what application do you use to stream HD content from phone via DLNA to TV ?
For instant I'm using IMediaShare from Market and when I stream a Full HD (1080) movie from my phone (by the way this is a movie recorded with the phone) the content is played after a while with interruptions , like is buffering or something.
The guys from IMediaShare tells me the bandwidth required to stream Full HD is at least 10MBps (notice Bytes not bits) ... so I'm wondering how can you do it at 802.11g (54 Mbps) ?

I use the Allshare app that came with the phone, no third party apps

That Allshare thing is not working for me, is not able to share the movie with my TV , it says it cannot share , where IMediaShare works fine (except the interruptions).
Anyway I'm not sure if Allshare works fine for you at 54Mbps streaming a full HD (1080p) from the phone ... did you really test this at 1080 ?
54Mbps =~ 6 MBps which is way under the minimum 10 MBps ... so I'm not sure what you stream at 54Mbps but maybe not Full HD content .

64 Mbps is good beyond HD Mbps rate
highest ive seen bluray go was 23 Mbps

No matter how hard I try, with my buffalo router the sgs2 doesn't go past 54 Mbit. The nexus one does, to 64, though.

Try Vlc.
Am pus odata pe un htc hd si am facut stream pe un pc. Incearca si vlc-ul. Wifi g. Bafta

And with WiFi it usually only comes to 1/3 of the theoretical speed. I mean has anyone ever seen 5mb/s over a 54Mbit/s link?

Either you or they are getting your units wrong - 10 megabits is more than adequate for internet or network-streamed H.264 video @ 1080p. A stream of 10 megabytes per second would make your average ethernet network (100Mbit/s) struggle significantly! Even the Blu-Ray spec specifies a max audio/video bitrate of only 48 Mbit/s (~5.7 Mbyte/s). (Source)

@thepriest thank you, too (sorry about that)
@hazzamon actually I was paying attention to that bytes versus bits , the guys from IMediaShare told me the problem I have is related the minimum required bandwidth 10MBps (Bytes not bits) -I have their email response .
But I did not have found anywhere (google it) the exact information for bandwidth required for streaming full HD.
But I've noticed something, my Linksys router has 2 antennas and is 802.11n compliant (with N-only at H-40 it reports a 130Mbps rate tough not sure what the real throughput is ).
But I've noticed the new Linksys routers with dual-range (2,5 and 5Mhz ~ 300 Mbps rate) and Gigabit ports are advertised as HD streaming compliant , mine is not advertised for that as it's an older model and not dual range.
So I'm really confused about the required bandwidth for HD streaming.
So my actual router reports a 130Mbps rate, the phone is connected at 65 Mbps, and Vaio reports 150Mbps (?) ... anyway the same movie (recorded by the SGS2 phone at 1080) is played fine for 1 minute and after it starts the interruptions, 1 sec interruption, 2-3 seconds play, then again interruptions and so on ...
Strange, the same thing happens with the same movie streamed from Vaio laptop , so in this case it looks like is not the phone's or IMediaShare's fault is either the bandwidth or my router or 10/100 switch or something else ?
And something else who is playing the streamed video, the source device (phone) or the receiver device (TV) ? Not sure my question makes any sense.
PS> thanks dialiv I will try vlc, too

I've tested this a litlle bit more :
Here is the bandwidth graphic (from dd-wrt router) where SGS2 phone is streaming via WiFi:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The phone reports a 65Mbps connection to the router.
And here is the bandwitdh graphic where the Vaio laptop streaming the same movie via WiFi (the movie is played a little bit better but still with interruptions - as the Vaio laptop reports connection to the router at 150Mbps)
And the same movie is played the best via Ethernet cables - very little interruptions .
So I think there is a bandwidth issue or I need to change the router with a dual one which support up to 300Mbps.
Tough I guess I will never be able to stream Full HD from the SGS2 phone as it can't get more than 65Mbps connection having a single antenna.

How busy is your local area for WiFi? The poor performance could also be caused by interference.

quite busy, I can detect at least 10 other AP, I've tried to find a free channel using WiFi Analyser

Low speed wifi - HTC HD

I have a wireless router(Asus WL-600G) in my room that support:
802.11g:6,9,12,18,24,36,48,54 Mbps
802.11b:1,2,5.5,11 Mbps
My PC connected to this router with wired lan and ofcource my HTC-HD connected to this router with wireless connection.
But in my phone's wireless LAN setting, in the box of Tx-Rate shows 54Mbps and in the box of Rx-Rate shows 1 Mbps(usually)(some times shows 54Mbps and then change to 1Mbps)
ofcource, I set power save mode to Best Performance.
When I use Resco File Explorer to transfer my files like .avi files, from my pc to my phone, my speed is up to 300KByte/s and it taking too long time, transfering my files.
And I can't watch my movies directly from my local Lan and continiusly my movie player(Core Player) buffering when i want to watch my movie so i can't use it to watch my movies directly from my LAN.
My question is, why my phone's rx-rate is 1Mbps when I have a router that support up to 54Mbps and why my transfer speed is up to 300Kbyte/s
Note: my devices are not so far(1 meter), and my signal progress bar is about 80%, although my Laptop in the same distance has VERY GOOD signal.
Have you tried the following http://forum.xda-developers.com/showthread.php?t=471910
i checked it, don't have any effect on my device !!!
have you tried changing the power settings to better perfomance??

In the thread to "make the wifi faster", they got a "wonderfull" speed up to 1900kbps... kiloBITS per seconds ! As kiloBYTES (the only interesting measure) it's an incredible ~240kB/s. It's just BAD for this kind of connection...
The WiFi on HTC devices is just there to be on the description of the device, cause it's just slower than a good HSDPA (around 4Mb/s or 500kB/s).
I can confirm I only got around 300kB/s using my G router. It's just not useable (you can expect a minimum of 1MB/s for a WiFi G and a max of 700kB/s for a B).

I want to know in this device we don't have a real speed wifi !!? or all other pda like omnio, Xpersia and iphone have same wifi speed
And with 200 kByte/s i can't see my movies from my LAN? because Core player continiusly buffering
It is important for me, I can watch my movies with my HTC-HD device
do u know any other solution to watch my movies directly from my LAN without pouse ?

I totally understand your problem, cause I'm trying to do the exact same thing (transfert avi and watching vids on my phone from my server using WiFi).
Yes - have exactly the same problem!!!
Router G mode, wifi G patch on HD, and speed about 200-300kB
I have the same speed problem with my home router ASUS WL-500w + sometimes it keeps disconnecting and connecting every 2 seconds.
I tried different WIFI router (Huawei) and it seems to work fine.
Tx-Rate shows 54Mbps and Rx-Rate shows 54 Mbps too.
+ with this router it was working on really long distance.
So i think the problem is in my ASUS router.
Today I'll try to use alternative firmware in my ASUS router. Maybe it will help.
Tried with 3 different radio roms, and with each ones, never more than ~300kByte/s... We don't even need WiFi G for this speed !
I wonder... is it because the device is defaulting to 802.11b instead of 802.11g?
one test could be to set your router to ONLY 802.11g......

[Q] Wi Fi connection speed on Acer Iconia A500

Guys: What kind of wifi internet speeds do you get on your acer iconia (using speedtest.net)?
I have a real problem. I have a N-router - Linksys wrt150n and a fast comcast connection - 25Mbps. Most of the times I get 30-32 Mbps download with the wired LAN connection (and an upload of 5-6 Mbps). My wireless b/g/n laptop (when tested on speed test) gives me anywhere between 17 - 19 Mbps UP/5-6 Mbps DOWN which seems reasonable to me. However when it comes to Acer Iconia A500 tablet, I only get 1 - 2 Mbps download/4-5 Mbps upload (tested at the same time as laptop). I know iconia is rated b/g/n. So why is there such a difference? almost 1/10th. Is there anything that I am missing?
My phone is 5 ghz and there is no interference that I can think of - If there was anything - it should affect the laptop wireless speed too. I have tried Dolphin browser, Opera browser, and the stock browser. Same results.
Please let me know if there is any setting on the tablet that needs to be enabled? Something else? I have fiddled with router settings also - auto vs n-only - almost same results.
Device = 3.1 HC/Stock Rom/Rooted
I just tested this - I get around 44Mbps for both download and upload with my n router. One thing though - I use the dedicated speedtest app, not their website. Can't run it on my laptop as it's still packed (I just got back from my vacation), but I guess the results would be similar because those are roughly the numbers I pay for.
Just tested it with the browser - I get 36Mbps for download and 22Mbps for upload. The funny thing is that after the test is completed it offers me to download Google Chrome - the "faster" browser . Yeah, right!

I get 72 from my Linksys/Cisco router and a fast Comcast connection. My laptop will go up to 300 but mostly stays at 144. I think this is because the A500 while using "N" it will only use it at 2.4 band (at lease that's what heard) the Lenovo v560 uses both 2.4 and 5 bands so I think this is the reasons for the speeds. I really don't have a problem at 72, fast enough for me with the tablet.

I pay for 10 down and 1 up. This is what I get with my tablet (just ran the test), and is typically what I get on my laptop, and desktop. I'm using a b/g router though as it's the only one I could find that I could get a 7db gain antenna kit for.

Your wireless speeds are backwards on both your laptop and tablet. Did you invert those by accident? Typically you get, and pay for faster down than up?
Wireless N speeds
I have a Linksys 4200 router and get 20 down, which is the level of service I'm subscribed to with Comcast.
HOWEVER, periodically, the tablet will downshift to 2-3 and stay there. If I reboot the A500, it still gets only 2-3. But if I recycle the router, it returns to 20. I'm still not sure what's going on, but in my case, this phenomenon is repeatable. I can always return to my full speed by resetting the router.
This is an old post but I know people are stii having problems. I tried to tweak my router ans always got about 2 meg down and 4 up. Was going through my garage sale stuff and found an older hawking antenna. What a difference it gas made in my 2 story house. Not always an option for some. Still havent tried much outside as I just got this.

You said you ran the tests at the same time which you shouldn't for several reasons:
1) Sometimes one device hogs more bandwidth than the other giving unfair results
2) The bandwidth will be shared (ie no one device will get top speed)
3) Power management on routers will cause fluctuation on the speeds even depending on how close each device is to the router
If you want a fair test, disconnect everything from the router (wifi and wired) and test one at a time (3 times each and take an average). Only that way can you be sure. Also try and keep each device roughly the same distance from the router when testing,

Mine recently is always just dropping signal. Is it the channel? Should I use 40mhz upper or lower? I know the basic channels everyone uses and try to avoid but is there something better. I tried using the upper , upper channels and it wont connect at all.
A500 speedtest problems
I know this is an old post... just wanted to chuck my results in.
I have 120MB DOWN and 9-12 UP (Virgin media) on a "Superhub" Netgear.
On the PC directly cabled I get those speeds +/- a few MB.
On the Acer 500 tablet, 6m away in the next room I get 0.8 - 1.2 mb DOWN - 1mb UP !!! If I sit right next to the router (0.5m) that increases to 2.5 mb DOWN and 3 mb UP.
Somethings is going seriously wrong here!!!
I´m not that tecky.. what can I do to improve this?
my speed
Ping: 10ms
DL: 31.37mb/s
UL:18.65mb/s
I just flashed a custom ROM ([WIP]A500/A501 JB-MR2(4.3) - V6 from Tegra Owners), and my browser and wifi transfer speeds are awesome (for the first time since honeycomb). It isn't the router. It's that ICS build that Acer unloaded on us. Unfortunately that custom ROM lags while going through android and won't let me play dots (huge lags). I don't know what I'm going to do because I can't go back to that stock ICS. Browsing the web was like being on a 56kbps modem (most of you are probably too young to remember that nightmare).
I wish someone knew a fix for the definite wifi problem on stock ICS so I could just go back to that.
BTW, when doing a speed test my speeds would ramp up to normal but were sluggish getting there. When browsing or transferring files they were always awful.

[Q] 5GHz WiFi on Nexus 10?

Okay, so we know that dual band WiFi is listed in the Nexus 10's tech specs, and I've had two Play Store tech support people confirm that it should indeed be 5GHz capable, but it just won't recognise or connect to my 5GHz network.
I've had 3 Nexus 10s now (all 32GB), and the behaviour below has been consistently observed on all of them, both in 5GHz only mode and Auto mode:
(The behaviour is identical on JVP15P, JOP40C and JOP40D)
- Does not show my 5GHz network in the network list
- Will not connect if the SSID and key are manually entered
- inSSIDer shows the 5GHz band as empty
I know this is not being caused by an issue with my network as I have half a dozen 5GHz capable devices all working on 5GHz without any problems at all, so my question is; has anyone successfully connected a Nexus 10 to a 5GHz WiFi network?
Thanks.
13 Jan 2013 - Just to update, it appears there could be ranges of channels the N10 will not operate on. These are 52-64 and 100-140. Channels outside theses range appear to work fine.
I would be especially interested to hear from anyone who has got an N10 working on channels 52-64 and / or 100-140.
Thanks.
I have a netgear router my nexus 10 connects to the 5gHz at 300 mbps
Sent from my SCH-I535
I have a BelkinN600 and switching to 5ghz is not an issue for me as well.
Do you have your Wifi frequency band settings on your N10 to run auto or strictly 5ghz? Maybe its checked at 2.4ghz?

Thanks for the replies.
jjdevega - I've tried this setting on both 'Auto' and '5 GHz only' and none of the 3 tablets I have recognise my 5GHz on either setting.
It seems improbable that I've got 3 tablets with exactly the same WiFi fault, so I'm rather stumped as to what's causing this.
Would both of you mind letting me know if inSSIDer shows your 5GHz networks in the spectrum view?
Thanks.
I can verify that 5 ghz works beautifully with the Asus NT-56 router as well.
Make sure the Channel Width (on the router) for the 5Ghz signal is set to 20Mhz, not 40Mhz or Auto.
5GHz worked swimmingly on my Nexus 10. Maybe it's an issue with your router?
It is a configuration problem on your own router if it is not working.
Yup getting the full potential of the 5ghz

Okay, I've been digging deeper into this and I've turned up something interesting.
None of the Nexus 10's I have here seem to work on the 5GHz channels numbered 100+
My network resides on 100 and 104 usually, and all my other 5GHz capable kit can use these channels just fine.
If I set my router to one of the lower channels (I can force the router to 36, 40, 44 and 48) then the the N10's see it fine.
Can I ask what 5GHz channels people are using? Does anyone have an N10 using channels 100+ ?
Thanks.
Mine is using channels 36 and 157. Both are Asus routers. I can see my neighbor's 5Ghz also on channel 157. Time to switch channels I guess.

Thanks, that's really interesting
I'm in the UK so can't use 157 - it's not a licensed channel here and so is disabled on the router Whereabouts are you?
It's curious though - all the channels that require dynamic frequency selection (and transmit power control in Europe) seem to be inoperable on the N10 (channels 52 - 64 and 100 - 140)
36 - 48 are only licensed for low power use, and don't quite provide the range I need. My router chooses 100 and 104 when set to auto and uses them at full power, and this provides the range I need. It's a shame the N10 doesn't seem capable of operating on those channels.
I'm in the States (Houston, TX). Unfortunately I can't use 100 or 104. I just moved my second router to 149, the lowest of the block of channels above 100 available here. I can't think of a way to test your scenario here. Hopefully someone from the UK will chime in.
I can't remember the exact conditions, but I was able to not have my 5GHz network shown on my Nexus 10 one time, and have it shown another. I was messing with channel frequency though, but can't recall numbers used.
Huh. I tried 5 ghz and it doesn't work. Why? Do you need a faster internet to make it work? Ours is 117 MB btw.

Okay, I've been digging deeper into this and I've turned up something interesting.
None of the Nexus 10's I have here seem to work on the 5GHz channels numbered 100+
My network resides on 100 and 104 usually, and all my other 5GHz capable kit can use these channels just fine.
If I set my router to one of the lower channels (I can force the router to 36, 40, 44 and 48) then the the N10's see it fine.
Can I ask what 5GHz channels people are using? Does anyone have an N10 using channels 100+ ?
Thanks.

I am using channel 153 at home. I dont have channels around the 100~ area in the States, those are for other countries.

Internet speeds shouldn't affect it; it's what wireless channel your router is using for 5GHz that matters. May want to play around with different values.

I'm in the States (Houston, TX). Unfortunately I can't use 100 or 104. I just moved my second router to 149, the lowest of the block of channels above 100 available here. I can't think of a way to test your scenario here. Hopefully someone from the UK will chime in.

No worries, thanks for trying. Out of interest, do you know what channels your router would select in automatic channel selection mode?

I can't remember the exact conditions, but I was able to not have my 5GHz network shown on my Nexus 10 one time, and have it shown another. I was messing with channel frequency though, but can't recall numbers used.

Thanks, that's consistent with what I've discovered. It seems there are indeed some channels the N10 won't work on.

Thanks. After experimenting with different channels I have my N10's all working on these channels now.

No, those channels are all licensed for use in the US.
With 5GHz WiFi, a lot of the channels require the use of DFS as part of their usage license. These are 52-64 and 100-140. Because the selection of these channels must be dynamic you cannot force a standards-compliant router to use them, which is why they cannot be manually selected. They can only be selected by the router its self when it is in automatic channel selection mode. In Europe those channels also require the use of transmit power control (TPC).
It appears that the Nexus 10 will not operate on any of these channels, however the reason for this remains unclear.
That means the N10 seems to only operate on 4 of the 19 licensed 5GHz channels in Europe, and only on 9 of the 24 licensed channels in the US.
I haven't ever set mine to automatic. I manually set them to opposite ends of the spectrum, but I could try using auto to see what they do.

Game streaming is useless over wifi

Lots of stuttering, input lag and low bandwidth warnings using 5GHz band with router only four meters away.
Thought this would be a good way to game on my TV instead of a monitor but it seems to be useless unless you content them using an Ethernet cable.
Would be nice if they highlighted this in more reviews, it seemed to work fairly well with the shield tablet but it's worse on shield tv.
Even over wifi the streaming stutters, I'm regretting buying this.
Apparently a ping of 4 isn't high enough for smooth gaming.
Hello!
I bought some TP-Link AV1200's and it's working nicely over these. I must add I'm living in a newly built house so the cabling will be up to par. Also my PC is on a different loop to my Shield but the throughput is still excellent.

Depends on your router actually. Have you tried connecting to the closer band? instead of 5. Also check your settings because routers now and days saves devices addresses which can slow down the process or you could configure your settings to your shields IP and give that top priority.
Are both the shield and pc on the same wireless network? I think it's worth it to run an Ethernet to the shield (or the computer) so you're not making the router/access point congested. A high quality wireless device with mimo capabilities might perform ok.
My setup has shield connected by Ethernet and my laptop on wifi, no issues here even using 1080p and high settings

I've tried with an Ethernet cable, sometimes it's very smooth but lags randomly which ruins the experience.
The software isn't up-to the job.

I can't even got it play nicely over Ethernet, testing over wifi further is a waste of time at this point.
So it looks that the problem is the router or internet connection. And not the shield. It's just a guess.
Can you test streams with a Laptop or PC via Wlan and Lan? Then you can find out
Thats strange I have had no issue with this good to know through.
Game streaming requires a 30 - 50 Mbps consistent connection (I believe). When it comes to wireless networking there are a lot of factors that affect your max. speed (connectivity protocol - a/b/g/n/ac ?, distance from router or access point, # of connected devices, interference, etc..,) ...
Actual wireless speeds vary significantly from the above theoretical maximum speeds due to:
distance - distance from the access point, as well as any physical obstructions, such as walls, signal-blocking or reflecting materials affect signal propagation and reduce speed
interference - other wireless networks and devices in the same frequency in the same area affect performance
shared bandwidth - available bandwidth is shared between all users on the same wireless network
Below is a breakdown of actual real-life average speeds you can expect from wireless routers within a reasonable distance, with low interference and small number of simultaneous clients:
802.11b - 2-3 Mbps downstream, up to 5-6 Mbps with some vendor-specific extensions.
802.11g - ~20 Mbps downstream
802.11n - 40-50 Mbps typical, varying greatly depending on configuration, whether it is mixed or N-only network, the number of bonded channels, etc. Specifying a channel, and using 40MHz channels can help achieve 70-80Mbps with some newer routers. Up to 100 Mbps achievable with more expensive commercial equipment with 8x8 arrays, gigabit ports, etc.
802.11ac - 70-100+ Mbps typical, higher speeds possible over short distances without many obstacles, with newer generation 802.11ac routers, and client adapters capable of multiple streams.

Works perfect fot me with asus router downstairs
I've been gaming loads through GeForce NOW, it's connected via ethernet through a pair of cheap homeplugs to the router.
Our ADSL is awful too, only 4Mbps asynchronous (500KB/s download bandwidth, about 50KB/s upload bandwidth).
I'm actually amazed it works so well - the video stream itself occasionally has artefacts or gets a bit pixelated, but it never stutters and never has any lag responding to gamepad inputs.
We're used to occasionally pixelated video when our ADSL fluctuates while watching youtube videos etc. anyway so this isn't a big deal.
It takes a bit of getting used to when gaming, but the overall experience is still fun and I accept that the video quality will get better when we move to a home with fibre.
Does anyone know how GeForce NOW actually manages to achieve such a native response time to gamepad inputs?
I find it truly remarkable that I can press a button on the gamepad and not notice any latency with the reaction on screen.
Surely any action must be sending packets over our crappy ADSL to NVIDIA's servers, routing them to the game's virtual machine, causing an effect in game, then streaming the video back over our crappy ADSL to be rendered on the TV.
I'd expect 100-200 milliseconds of latency at either side of that transaction (even over UDP), which I'd expect to ruin the gaming experience of real time games such as FPS / racing games.

Also using an Asus Router, it still sucked.

Another thing to note, WiFi is a half-duplex CSMA/CA connection. It can either send or receive at one time, not both, like Ethernet. Collision Sense will "listen" to see if anyone is broadcasting. Collision Avoidance will set a random timeframe, when transmission will retry. While this is happening extremely fast, there's a chance to lag there. If you must use WiFi instead of ethernet, try to dedicate a separate SSID for streaming, and make sure that nobody else connecting to that particular one. Try to set it to uncongested channel as well.
Unless you have one of the newer routers mu-mimo and other new software helps keep wifi onpar with ethernet
Works fine here. Asus Router is several rooms over and using a USB wifi stick in PC.
So its probably something other than the shield.

Didn't realize that. Will look it up.
I can't get this to stream from my laptop. It says that i need a GTX 600 series or better but my laptop has a GTX 770M.

Anyone streaming 4k LOCAL content (videos and moonlight gaming) without issue?

I bought a 4k TV for my bedroom, and am having difficulty getting a quality LOCAL connection from my router to my ShieldTV and am questioning if the ShieldTV's wifi module/antenna is the weak link. When I stream 4k videos, it always buffers, glitches badly, audio messes up, and when i try to game it lags pretty far behind despite moonlight saying i have low latency. So I am curious if anyone has this working without buffering or lag or glitches. If you have it working, please reply with your setup and anything you had to do, even if you dont know how to help me, below is a short explanation of my troubles.
Im in a (wifi congested) apartment complex, my apartment layout is basically:
Living room|Kitchen|Bedroom.
It's 2 walls and 23ish feet between my router and bedroom spot. There is only one cable spot (where my modem and router are) and zero jacks for Ethernet.
I originally thought my Netgear Nighthawk R8000, could push the signal well enough wirelessly, as everything is 5ghz AC and I only have 1 other device on it (also 5ghz ac), but I was only seeing 100-300mbps.
I have put the shieldTV next to my router and is works perfectly via lan, so I know it isnt a performance issue of the server (desktop) or shieldtv and only a question of getting a good signal.
So I just bought powerline adapters Trendnet TPL-421E2K, which were some of the best I could find in multiple reviews, and those perform roughly the same. If I put them right next to each other on the same wall, i get 600+mbps, but the max i got with them between rooms is 200mps, and thats with trying all the outlets and removing anything that could interfere. Guess wiring just sucks.
I am pretty much out of realistic ideas on how to make this work. The obvious, but not realistic solution is running 20ft of ethernet on my floor or taped to the ceiling.. But I am starting to wonder if the shieldTV just has crappy wifi and i'll never get this working.
Are you checking your speed with speedtest? I play 4k content on the fly and it works, unless bitrate is over 50, then it sometimes goes wrong.

Speedtest checks your ISP speed. I am using a an app called "wifi speed test" that allows you to test your local internet speeds.

All of this
5GHz degrades faster than 2.4GHz due to distance / obstacles. Use 2.4GHz (not that this will help because of below)
Wifi is a shared, collision based medium. High density domestic wifi environment means highly variable latency, throughput.
4K uses a **** load of bandwidth
NVidia Shield streaming appears to me very latency and bandwidth sensitive (see above 3 points).
Sorry ethernet or bust for 4K ... I couldn't get it stable using Wifi in the same room even without wifi congestion.
