WIFI speed drop with ASUS RT-N56U - Nexus 4 Q&A, Help & Troubleshooting

I'm on stock 4.4.2 rooted with franco r199 running on the .98 baseband. Using an Asus RT-N56U router (upgraded to the latest firmware - 3.0.0.4.374_979), running on both 2.4GHz and 5GHz.
When I first setup my router, I can get download speeds of up to 55Mbps using the 5GHz channel. Pretty good. However, in less than an hour, when I do another Speedtest, the download speed drops to 10Mbps.
My temporary fix is to tweak the Control Channel in the router, setting it manually to 40/44/48 etc. Right after a soft reboot of the router, my download speed goes back to 55Mbps.
However, the problem recurs every time, and it's frustrating that I have to always switch around the channels in my router settings page just to get my download speeds back up. The speeds before and after the drop are consistently similar.
I have tested on 2 other phones (Samsung Galaxy Note N7000 and Motorola Atrix). Neither of them has this problem with the router, and when the speed drops to 10Mbps for my Nexus 4, it stays at around 50Mbps for the two phones.
I tried flashing back to the older radios (.48, .84, .97) but the speed does not improve. Still requires the channel changing mentioned above.
I have used Padavan firmware for the router before and the problem recurs as well.
Any suggestion?

Just an update. My WIFI speed will temporarily go back up to 55Mbps when I go under Advanced under Wi-Fi Settings and toggle between Auto, 2.4GHz and 5GHz.
It's looks to me like an alternative temporary fix just like changing the channels in the router settings.
I mention temporary because the speed drops back to 10Mbps after a while.

[Q] Wifi Speed

Hello all,
I've had my Nexus 10 since Christmas and it's never given me any problems. Within the last 3 or 4 days, however, I noticed my videos weren't loading like normal, so I've been running speedtests and it is completely inconsistent. My phone and computer will consistently pull 20+ Mbps, but the N10 is crazy. Sometimes it's 3Mbps, sometimes it's 10Mbps, sometimes it's 16Mbps. Every time I check, it's different. I've used multiple programs and websites to read the speeds, and they're all reporting the same. I can stand in another room, or right next to the router, same story. The wifi never fully drops, it just slows way down. I don't have a case on it. I've turned on and off the Wi-Fi optimization in settings. I've turned on and off location settings. Nothing helps! Please let me know if you have any ideas. I am hoping I won't have to return the darn thing, it seems crazy.
As per my internet, it's Comcast, Surfboard modem with a Linksys E1000 (Wireless-N, 2.4GHz) using WPA. Restarting that did not help. I am open to the idea of changing some settings on the router however, if that might be a solution. Also, signal strength on the N10 says "Excellent" and link speed says 130Mbps.
Thanks for your help!

I too have this problem so now Im going to attempt to root the device
Glad to hear someone else is having similar problems.
Possible good news: I changed my protection from WPA(mixed) to WPA2, and so far things seem to be much more consistent. This may just be a fluke, but it's looking much better so far.
If you have a router with 2.4GHz band only, try changing it to 2.4GHz under WiFi settings on the Nexus.
I had some disconnection problems due to that and somewhat inconsistent speeds, I've seen it fix a lot of peoples problems, I've yet to have a transfer problem so far with limiting WiFi to the speed of my router.
Other issues some see is using N wide or dual channel (40Mhz). As the N10 only supports 20 Mhz in 2.4GHz it seems to get confused.
Most other devices either support 40GHz or handle switching more gracefully.
In short force router to 20 Mhz/single channel, may report more consistent behaviour.
On 5Ghz it does not matter as the N10 supports 40Mhz/Dual channel.
Odd, I know.
My experience is that sometimes with wifi issues, wiping the cache (if custom recovery is available) would resolve the issues for some time, but it might be due to an beta ROM.
P.S> on 5GHz wifi I am able to hit 122Mb/s
it has WIFI, mine hardly works
After a few hours of testing, I am now consistently getting 20mbps + as I should be. My router is set to 20MHz only, but I think the main issue was the security settings. It just wasn't dealing with WPA(mixed) well.

[Q] awful Nexus 10 wifi speeds

First time poster here. I've searched all the threads and couldn't find anything on my specific issue.
Had the Nexus 10 for about a week and noticed streaming YouTube and movies was EXTREMELY slow. Slower than my Galaxy Nexus on the same WiFi network (my network speed is about 18-20 Mbps). I finally did a speed test and noticed that my 10 was getting awful results...sometimes 3-6 Mbps while sometimes it'd get up to 10-13. My Galaxy Nexus gets between 14-18 Mbps consistently. For my 10, every speed test fluctuates between 3 to 13 and it's just so inconsistent.
Now, I don't have any connectivity issues. It never drops the signal and I'm always connected, it just goes super slow to the point of YouTube videos not loading.
I'm not a wizz, but I use ATT uverse and use the router they give you. I'm not sure if it's a router issue or a Nexus issue.
I've restarted the nexus, turned off the WiFi optimization and turned the WiFi off and on. I had a ton of issues with my nexus 7 (main reason I switched to 10) and I really don't want to ship the device back to Google. Any suggestions??

For starters when you toggle WiFi optimization you need to reboot for the setting to completely turn on/off.
What ROM / Kernel combo are you using? If that is stock then it is likely the router.
ISP routers are usually cheap, they don't handle multiple device traffic very well. One thing you can do is change the stock/auto settings they come with as they are less than desirable. Lower channels/and or Auto Channel (in both 2.4 and 5 GHz), QoS, software static IP, and even Google DNS can all interfere with your router. First go into build.prop and look for the 8.8.8.8 and 8.8.4.4 lines and delete them, reboot. Try that. If issues persist go into router firmware and change all the Auto settings to a preset. Even something as simple as your phone logged on at the same time could interfere if the channel is saturated. Take everything off the WiFi except for the n10 and try that. Getting a 3rd party router with dual band / 802.11n support is ideal.
The least likely issue is that it could be a hardware issue with your n10.

N4 5ghz connection

I bought a new router a few weeks back for the express purpose of using 5ghz. I set it up and I remember it working at the time, but stopped soon after and I never looked back into it until now,just used the 2.4.
I can see the network, and a few other 5ghz networks in the area, but when I try to connect the signal strength drops and disappears for a few seconds. Looking at 20 ft line of sight.
I've set the router to 20mhz band, used every available channel, and disabled encryption. Nothing so far. Any suggestions?

Not that this helps but my wifes N4 cannot connect to any 5GHz network either, i have tried changing the channels etc. but to no avail.
It used to work brilliantly with 4.2 so the blame lies with Google in the latest updates.
I've searched for your problem and I've found that some channels were missing and google added them in 4.4 update ...what android are you on ?
Stock 4.4.2, nothing i have found works thats for sure.
I am having a similar issue, 2.4ghz signal is full strength but 5ghz struggles to keep one bar whereas my Nexus 7 is full strength on both.
Router is an Asus RT-N66U and I'm running CM11 Snapshot M2 on both devices.

Wifi problem - what router do you use and what is the configuration?

Some people have no problem, while others like myself have issue. So let's figure out if this is a router config issue, since most Wifi problem with Android have to do with the router itself. I'll start off with mine.
Tablet date of purchase: September 12th
Router: ASUS RT-N66U dual-band (2.4 & 5 Ghz) with latest firmware
Wireless configuration:
- 2.4 Ghz for B/G
- 5 Ghz for N only
Distance from router to tablet: less than 50 ft
Issue: sporadic network connection. I got full Wi-fi signal bars, good Internet connection, but then cut-out and no connection. Back again after 10-20 seconds.
Fix(?): Changed the router configuration for the 5Ghz radio from 20/40 Mhz to 40 Mhz. This seems to tame the problem. I still have sporadic connection, but far less and connection is back again after a few seconds.

I have a TP link single band N router configured for b/g/n. Both my shield portable and shield tablet have issues with wifi. My nexus 7 and my moto g are perfectly fine on it.
I think in my case I've narrowed it down to the router, though. I have a second router upstairs, also tp link single band N (different model). It is configured in bridge mode for the main router. Both shield devices are perfectly fine when connected to it. Unfortunately it only serves a small portion of my house and is much slower over all.
A robust wifi area will hide most any weak wifi. Catch is most areas are not robust.

What do you mean by robust? Not crowded?
Strong signal with minimal set up conflicts.

I'm using a similar setup, but an ASUS RT-AC66U instead of the N66. A frequencies are mixed-mode, and my 5GHz is 20/40Mhz. I can pull a consistent 20 Mbps down usually, without any issues. 50 Mbps down if I'm the only active network user at the time.
Wifi signal is usually at 2 bars, but I'm getting the same signal level out of the Shield Portable, my Nexus 5, and Nexus 7 on my 5Ghz net. My 2.4Ghz net is usually always full strength.

That's interesting. I wonder if my N66U is unable to maintain a stable and consistent 5Ghz connection. So you have no problem with the connection like mien?
Do you use DD-WRT or stock ASUS firmware (what version?). I may end up buying the AC66U just to test it out.
Using a virgin hub which is a netgear i belive, 2.4 is solid even two stories away from the router. 5g is still there 2 stories up but will drop out, only 1 story up it's 1-2 bars but never drops out. 5g band on router set to 38-40ish range.

Don't you need 5Ghz to play GRID? If I use 2.4Ghz, GRID will "complain" and won't start any game I selected.

I have the AC66U as well and have no problems at home but have severe wifi difficulties at work or when hotspotting to my mifi which is annoying.

Stock. Whatever the latest version of firmware is too- I update when it's available.
When I had problems with my Luxor tv connecting changing channel on router from auto to one of the numbered ones fixed it, perhaps it has the bug where your device ends up getting the same IP as the router. Worth a go!

5.0 5Ghz Wifi Issues

Did a full image wipe/install with the official 5.0. I'm no-longer able to connect to my Netgear r6800v2 router with the same channel 48 setting for 5Ghz that previously worked on android 4.4.4.
Any other folks out there with android 5.0 problems using 5Ghz channel?
EDIT: I should add - I'm fully aware the N10 has limited 5Ghz frequencies it works on (e.g. 40, 44, 48) - I've tried 36, 40, 44, and 48... none of these seem to work in android 5.0 with the same router settings. It can see the broadcast and attempts to connect, but IP address is never acquired (DHCP)
I'm having the same issue and my 2.4 network is very slow. Anyone else have this issue or any idea how to fix it.
Yeah I've had issues with 5ghz on every lollipop device I have. Haven't figured out how to fix it yet
I had the same issue and changing to Channel 44 (with Auto bandwidth = 40 mhz) solved it for me, it was on 36 initially
No problems here, did a clean flash of Lollipop and 5GHz is working fine with my RT-AC68U, channel 36, auto bandwidth.
Same problem here. Changed to channel 44 and is at least working
Wiped. Clean flash. No problems. On channel 157. Wish it would tell me if im 300mbit or not. Ac n66u.
Installed from a sideloaded OTA.
Have issues connecting to my Virgin Superhub 2 both on 2.4Ghz and 5Ghz.. Channel 8 and 36 i believe.

Go into Settings -> Wifi then tap the connected wifi network. It will tell you your link speed there. Mine is connected at 300mb/s, while in powersaver mode it drops to 24mb/s.

Mine only connects at 24Mbps and its not in powersave mode
I've similar issue, but both on 5ghz and 2.4ghz.
The connection isn't stable and I get disconnected all the time after upgrading to lollipop. If I'm tethering with my phone right next to the tablet (on 5ghz) it works perfectly. I'm not sure if they've tweaked the disconnect/reconnect threshold base on signal strength.
I'm having problems with 2.4 Ghz wifi too. In Jelly Bean I have a pretty good coverage with my home router but with Lollipop I get lots of disconnections and slow speed. I'm not sure if it's a drivers problem or an operative system change, but I know for sure that it's a pain in the ass.
I'm having the same problem with 2.4 Ghz.
Both 5 and 2.4 are much worse for me as well compared to kk.

I've solved my Wi-Fi speed problems changing one setting in my router: just disable WMM ( Wifi MultiMedia).
Try to enable/disable that setting (can be shown also as WME instead of WMM).
Good luck!
wifi is terrible after 5 update, on both 2g and 5g, constantley disconnects and not loading pages :crying:

My 2.4g is working perfectly, but it cannot see my neighbours 5g network. My Note 2 sees it fine. I checked with Wifi analyzer app.
I can connect to my BT home hub 5 but it only works for a free minutes and then it kind of freezes.
I'm still connected according to my tablet with good signal strength but there is no internet activity making the tablet pretty much a big paper weight for me at the moment.
If some one can help me fix this issue id be very grateful

Connecting just fine at 5GHz 300Mbps with 5.0. I have tested 2.4GHz as well and both function just fine.
I do connect easly, but connection quality is poor... There is definitely something wrong with Wi-Fi on lollipop
