wifi issues on N4 possible fix?

for those with wifi 'broken' try to change your router settings to WPA2 personal (TKIP+AES) that seems to work for me now,
other settings 'broke' the wifi
this might be just an issue with must me and my router
*spoke too soon: still broken, it only works certain times, mostly it just spins when i try to connecto to online
the wifi icon keeps flashing a black dot... that means the wifi is NOT working right? it should be just a solid blue bars?
on wifi advanced settings, WPS Pin Entry - what is this and do i need to enter that pin on my router?

still no luck with wifi on my network after flashing back to stock 4.2 from 4.2.1
same 'broken' wifi
might be this phone's wifi hardware is incompatible with wDDRT router?
Firmware: DD-WRT v24-sp2 (10/10/09) std
my other wifi devices work perfectly fine, so im really stumped
in phones advance wifi settings it has this WPS entry - what is this and is it somehow not allowing me full wifi?
i can view playstore,, it checks and loads my gMail but it won't connect to websites
it takes so long to download and install apps from playstore, i have to hit cancel, redownload, reinstall to get it working,etc. its not 'instant' like normal 20Mbps wifi should be
ran speedtest.net app and it wont connect to any servers
if anyone has clues to why my wifi is broken, please PM me thanks
it get a blue 3 to 4 bars on wifi signal but it keeps having this 'black' dot flashing in that wifi signal bar, (what is that?)
shows connected to my wifi at 72Mbps at good strength

I found my solution: in my router I unchecked the option WMM (Wi-Fi-multimedia)-settings (2.4GHz b/g/n). After I activated it, my data speeds increased enormously. Try it & report!

My n4 will not connect to any of the WPA2 AP's around here.

I have the opposite problem. I can connect to my WPA2 router at home just fine but cannot connect to the WEP wifi at work. Well, not reliably. I've gotten connected twice, but was unable to recreate the conditions.

I had speed problems with my 5GHz band at home. Connected, but couldn't get over 1Mbps on my 30+ connection. Connected to the 2.4Ghz band and I get significantly faster speeds. Haven't had problems connecting though.

I've noticed similar behavior, seems like my 5ghz signal strength is much weaker than my 2.4ghz signal according to my n4.

So this n4 is picky about. Certain WiFi networks.configs

Sometimes, my N4 loses wifi connection at work. It's inconsistent. My work wifi is open but MAC filtered.
There have been 3-4 times when I noticed that it lost wifi connection. I had to turn off wifi radio and back on to reconnect.
OTOH, connection to home DD-WRT wifi router is rock solid.

Set lease time for as long as possible, it normally this is 2 weeks..

very strange !!!!
can you test to flash back CWM recovery and test again the wifi ?

Hello, I am also having problems with WIFI. I've tried a lot of things (change the router configuration, the cellular exchange kernel, etc ...) but I could not fix this problem. Can you give any more ideas? I've even thought about buying another router but can be giving the same problem.
I used my wife's phone as a router and it works normally, but when I connect directly to the router from home and he trasfere data only for a few moments and then transferring data, although still seem the symbol of wifi connected.

I found changing a setting on the Nexus 4 seems to have remedied most of my WiFi issues. Forcing the WiFi frequency band to 2.4GHz only instead of Auto appears to have done the trick for me.
In WiFi if you select Settings and Advanced under Wi-Fi frequency band there is an option to force 5GHz or 2.4GHz with the default on Auto.

5 ghz WiFi no Longer works 4.3?

I just setup a 5.0 ghz wifi router today. My nexus 4 doesn't seem to be able to connect to it now that I am running 4.3. I can see the ssid. I type in my password WPA2 and it reports saved under the network ssid. However no matter how many times I tap it, it never actually connects. I tried everything from restarting to flashing 4.3 again. Nothing helps.
I read several threads and reports about people experiencing slow speeds on 5 ghz after the 4.3 update but no one seems to mention not being able to connect at all. Some posts suggested that it works for them if they remove their router's password but I don't want to do that. I'm wondering if anyone has been able to use WPA2 and be on 4.3 successfully.
It's not a network or router issue. The router works perfectly with every other 5 ghz device that I have.

try changing the channel on the 5Ghz network, as some phones/tablets are quite fussy about what channel they work on!

This just started happening to me as well. I was away from my normal WiFi networks for a couple weeks and also updated to 4.3 and had to reboot the phone once or twice. Now I can't connect to any 5 GHz networks. I've tried 3 different networks that were all set up on my phone previously. I've tried "forgetting" them, turning off WiFi and then turning it back on, rebooting the phone, no difference.
On some networks, my phone doesn't see the 5 GHz band at all and on others it shows up until I try to connect; then it disappears.
Android 4.3 just seems to be another piss-poor update in a tremendous string of crappy software "upgrades" for me: Win8, Intel Centrino 6235, Google Maps, Hangouts. Quite the string of bad luck. It's like the world is telling me I need to buy Apple...

Drop the channel down to 36. All shall work then. This issue is in the note 2 and note 8

OP: changing channles fixed it for me..

Same boat. Tried low and high channels. It does see it. CM10.2.

In my case I do not see 5 ghz network at all. I set it to be on chanell 44 (20 Mhz), no security - still the same issue.
Also I realized, that even if in Wifi Advanced setting I set "5 ghz only" I still see 2.4 chanells.
I am running latest stock 4.3, no root.
4.2.2 same config worked ok.

5 GHz works fine for me. Do radio firmwares also effect Wi-Fi and Bluetooth?

I was having the issue. None of my devices were connecting. All on 4.3. But I rebooted the router and it's been all good since. It may have changed its channel though. It's set to auto channel. But all my devices connect no problem. Using 40mhz and n only since AC not supported on nexus 4.

I'm pretty sure it's the kernel, unless LG does it differently than HTC.

What happening if you go to wifi settings , advanced and select Wifi Band - 5 ghz only ? Do you still see 2.4 AP's ? In my case, I do. In 4.2.2 I did not.

Interesting - as I am still get 2.4 AP's. I used a factory default images for JWR66Y to un-root and get full stock (only bootloader remains unlocked).
And even with full stock , un-rooted I got the same problem. I was using Purity ROM with Franco kernel before that - with the same problem.

I did some more tests, and I found that immediate after reboot, I can see my 5Ghz network AP, even connect to it.
However, after few hours it was inaccessible. Also, nerveless what I do, if I select to use only 5Ghz band I still see 2.4Ghz AP's. No idea why.

Both my N4 and my N7 (2013) won't connect to my router when it is using WPA encryption. My N10 is fine though. I have had to lower encryption on one frequency band to WEP - which I'd rather not do, but it is the only way I could get it to connect.
It seems sensitive to brands of router, as both devices connect to my work network fine and that also uses WPA encryption.
My home router is a TP-Link Archer C7.

Hi,
I have this issue logged with Google at the moment regarding the 5Ghz issue. They are fully aware of it and say numerous customers have been affected - their original solution to me was to downgrade to 4.2 and lose my warranty. When I said won't do that they offered RMA which 2 weeks later I'm still waiting for them to sort.
According to Google just because other devices work on 5Ghz doesn't mean the Nexus 4 will, so I can't how they can sell it stating it works with 5Ghz when it doesn't.
Also have post here
update: received my replacement phone on 21/09/13 and this is running 4.2.2 and connects to my 5Ghz without any issues - done a side-by-side video of the faulty phone running 4.3.3 and sent this to Google - I have told them it was working fine before update

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.

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!

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

Peculiar Wi-Fi issues

I have my nexus 6p, currently using DU 10.2 for my ROM, and its been great up until 2 weeks ago. I am currently working at a summer camp in the boonies so wifi is helpful for not racking up data usage. And I was having no issues until recently. We went on a trip to the dunes and then when I get back I can't connect to either of the camp's wifi's, secured or unsecured. On the unsecured network, it never is able to obtain the IP address and on the secured, I'm guessing the same thing but it tries to authenticate and cannot. But oddly enough I can connect to any other network like when I go to a cafe in town or another home wifi.
I have tried all of the basics, airplane mode, reboot, and discharge battery. I even tried rolling back to a backup from May. Whats more I got around to checking the DU updater and saw that I never got to 10.3 and tried updating directly to 10.4. Maybe that was a no-no but when I did it, no networks even show up, it can't even find any of them when I know I have connected to them earlier that day.
So there's my dilemma, and I hope there is someone who can give me some insight. I don't believe it's a hardware issue because it's only these two networks, which I'm sure are sharing bandwidth.
Cheers

I've had similar issues sometimes when trying to access a friend's WiFi. The only way I can connect to the network is to change my WiFi frequency band from automatic to 2.4 ghz. What frequency is your phone set to? You could try to change it, and see if it helps. I've also done a reboot, and was then able to connect on automatic.

all 5GHz wifi will disappear sometime

Hi there,
i found that all 5GHz wifi will disappear sometime and only 2.4GHz wifi were left even the signal is very good.
Not only mine but also my neighbor's 5GHz wifi was gone too so i can confirm that there is no problem with my router.
but it can be solved by restarting WIFI in setting menu.
is that a hardware bug or software bug? have anyone facing this problem too? :crying:
ps: using stock rom 4.5.5 & stock kernel

I've too, but disappear and restore itself.

I have the exact same issue, I have 2 separate routers, one upstairs and one downstairs. The one upstairs is a 2.4ghz router and the one downstairs a dual-band router with separate SSID's for the bands, sometimes when I come downstairs I can only see the 2.4ghz SSID not the 5ghz one.

but the 5ghz one shown when u restart wifi, right?

Have you guys already contacted OnePlus about this? I have a few days ago, and I'm currently still in touch with them to find out why this happens.
I for example have the problem, that sometimes the data throughput using 5 GHz networks is absolutely zero, no data is transferred at all (tested with iperf3) and then sometimes it resumes but other times I have to disable WiFi entirely (disable background scan to do that) and reconnect and only then it would start communicating again.
BTW: I'll include a link to this thread on my ticket with them, so that they can see I'm not alone with WiFi issues on the 5 GHz band.
