[Q] Wifi Issues?

After reading a bit it's seems to be a common issue on ICS and later. My device occasionally looses it's wifi connection, at which point I have to go to settings and turn the wifi off and on. Is there a better solution to this problem? My router is using WPA2-PSK and is on channel 7.

Wifi seems to stay on fine here, but I cannot connect to 5ghz, only 2.4ghz. Not sure if this is an issue or if the Wifi chip only supports 2.4 ghz.

it doesnt connect to 5ghz, unless theres a trick to it??? but use wifi analyzer and look for the strongest channel on ur wifi router to fix ur problem

Turn off multimedia support on your router if all else fails

5 GHz band is not supported

Yea I'm having trouble as well. I have a telus smart hub at home and it is super slow. Then when I use my hotspot on my Gnex from rogers, it runs fine, although this app takes awhile to load.
Tried playing with the settings, only think I couldn't find was the 5ghz and 2ghz.
Try some more playing tomorrow and look for different routers

Can I ask someone with nexus 7 to check if it connects with wifi AD-HOC network without problems?
I use my old LG gt540 as a 3g modem + wifi router, but it works only with ad-hoc. For example my HTC Sensation can't connect to such a network.
edit: NO, it does not connect with AD-HOC

Obtaining IP address after update to 4.3

Hi after updating to 4.3 connecting to my WiFi seems to just keep looping obtaining, authenticating, obtaining. This didn't happen in 4.2.2. Anyone know a fix?

Try another network. Maybe it has a problem with your network. Hit thanks

Try forgetting the access point and redo it.

Yes it works on other WiFi networks but does not mean the one I am having problems with is faulty cause other devices connect to it just fine. Not to mention it worked perfect on 4.2.2

WPA2 PSK. Also I want to note that this is a second router connected to the main one by ethernet and used as an access point

Have you tried checking the router settings?

I had the same issue before 4.3 update. It was working fine after the update but today it happened again. I switched to static ip in my nexus wifi settings and its working fine. So i guess DHCP has the problem and im blaming nexus because everything else in the same network works fine.

I have the same problem with my old generation nexus 7. New one works just fine, galaxy nexus - just fine, xperia s - also fine, macbook pro - fine. I can't blame the network. Something is messed up. I tried a factory reset (as I'm selling this one) and it didn't help. also after quite some time of trying it wrote "Avoided poor connection" under the name of my network, but I can't alter the "Avoid poor connections setting" from the setup wizard.
Any help is greatly appreciated.

I think the problem is DHCP too. I used to use WPA2 for my LAN. My Nexus 4 appears to not connect to those networks anymore.

Tried to set a static IP address? And you could also playing with the WiFi frequency bands. Some reported they can't connect to WiFi on 5 GHz band. Could try the 2.4 GHz one instead.

In cases of weak signal, DHCP may fail when connecting. If this happens, move closer to the AP (stronger signal).
If you have 2 routers and use 1 as an access point, use the LAN (not WAN) port on the second router and disable the DHCP server on the same router. You can use the same SSID and float between them if the other settings match (encryption and password). Use 2 different channels as far apart as possible (like 1 and 11). On 2.4 GHz, only use channels 1 to 11. On 5 GHz, only use 36, 40, 44, 48, 149, 153, 157, 161, or 165. The other channels have FCC limitations in the US. Use WPA-2 only with CCMP (AES) encryption. WPA should only be used with TKIP, while WPA-2 should only be used with CCPM (AES). I have seen a lot of issues when mixed is used.
Hope this helps...

Thanks for the suggestions. While testing I was standing just beside my router, so no weak signal problem. What I did after many tries to connect was reinstall stock 4.3 but version which ended with the letter 'V'. I was unable to see my problematic android build version, because I was stuck at welcome screen. So the reinstall fixed it.

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
As well.

yeah wait till tomorrow.. you might well see a "crappy updrage" of apple...
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

Nexus 4 Broken 5Ghz Wifi

I therefore conclude that my 5ghz WiFi antenna is broken. Reverted to both stock 4.2.2 and 4.3. Tried custom ROMs, different radios, but it won't connect anymore. Anybody else have the same problem?

I just got a new belkin 1200 AC router and though I can see the 5ghz network, when I try to connect it disappears. So, the 2.4ghz seems to work fine. I did run into this at a restaurant that had both options and the 5ghz never gave me a signal, but that was months ago and might have been prior to CM10.2?

On my N4 Wi-Fi work only on 2,4 Ghz band

could mine also be broken? it suddenly slowed down out of nowhere

Just tested my Nexus 4 (CM10.2 Nightly, AK v0.51) with Liksys WRT320N and WRT610N, have connect on 2.4Ghz/5.0Ghz on both routers.

[Q] Nexus 4 does not connect to 5GHz Wi-Fi network

Hi,
I have both a 2.4GHz and a 5GHz Wi-Fi network, but for some reason my Nexus 4 can't find my 5GHz network. Anyone know of any solutions? I'm running Android 5.0.1 stock.

Hmm, still wasn't able to get it to work.. I've reset both my modem and my router as well, no luck.

This might be a lollipop issue, as i remember reading somewhere that lollipop has issues with 5GHz Wi-Fi bands. If you are willing, you can try downgrading to 4.4.4 KitKat and giving it a shot.
