[Q] WiFi works fine but takes ages to reconnect after falling back to 3G data - Nexus 4 Q&A, Help & Troubleshooting

Hi all
I've been running CM 10.2 for a while and had no problems with it, but wanted to upgrade to Kit Kat so I flashed CM 11 via the Installer apk. Everything works great except I'm finding that if I go out of WiFi range and the phone falls back to 3G data, it won't reconnect to WiFi when I come back within range (e.g. when I get home from being out). Further details:
- manually reconnecting through settings DOESN'T work... it sees the networks but hitting 'connect' does nothing
- disabling the modem entirely via flight mode and then re-enabling DOES work... WiFi reconnects automatically
- the phone WILL reconnect by itself without flight mode but only after quite a long while
Anyone else experienced this behaviour and know of a fix?
Thanks!

[Q] Wifi to 3G hand-off problem and vice versa

I'm running Cyanogen 7.2 stable on my Droid 2
It seems I cannot successfully transition from wifi to 3g, or from 3G to wifi without hard resetting my phone. If I turn wifi on, then hard reset the phone, it will connect to my chosen access point, I'll get an IP address, and be able to use internet. But when I go into wifi settings and disable the WiFi, it will claim to connect the 3G but I will not be able to connect to any internet site. The notification area will show 3G icon in white, but never turn cyan to indicate a successful data connection. Trying to turn on airline mode does nothing, and the phone will not go into airline mode until I also, turn it off and turn it back off. Then it will reboot into airline mode. A simple soft reset doesn't seem to solve this problem, I have to preform a power off, and then turn it back on.
Conversely if I set it to use 3G and hard reset it will successfully connect to 3g and work fine, but turning on wifi will result in a connection to the access point but no actual data tansfer. Just as before it will show the connection option's icon on the notification bar will show the WiFi icon but it will say white, and never successfully connect. Alternately wifi will connect and the drop the connection repeatedly.
I've looked all over here, and Google for any working solution but I haven't seen any. Mostly just people having trouble connecting to a specific router, which I DO NOT have. Specially the hand-off to 3G and back seems broken and I have to do a hard reset 100% of the time to change from wifi to 3G and back.
Could somebody point me in the right direction for a solution that hopefully won't involve wiping my phone?

[Q] Nexus 4 with AOKP won't connect to Wifi, "WPS failed" error

My Nexus 4 isn't connecting to wifi. More specifically, if I am connected to a remembered network, my phone does not automatically reconnect when I leave the range then come back into it.
Now, there are 2 wifi networks in the apartment and I've tried both. I actually just "forgot network" on the last remembered network on my phone because I was trying to connect to the better one.
Since I've done that, I am unable to connect to wifi at all, because the only way for me to connect to wifi before was to restart my phone and have it automatically connect to the remembered network.
Now that I don't have a remembered network, I cannot connect to anything, and my Wifi page on my phone will not show any wifi networks available and it won't even give the option to turn on wifi or to refresh the list. I have to reboot my phone, making sure the wifi is off first (using the toggle on the dropdown notification menu), then I can at least refresh the empty list. When I refresh the list, it gives me an error, "WPA failed. Retry in a few minutes."
I need this fixed. I live in a basement apartment and my cell signal is usually unavailable while I'm home.
I was running the AOKP 4.3 milestone when I started having the problem, then went back to stock, put on a 4.4 nightly ROM, had the same problem, then went back to the same 4.3 milestone. Unfortunately, I didn't leave my phone on stock 4.4 long enough to see if the problem persisted there.
Is there anything I can do at this point before going through the process of bringing my phone back to stock again?
Thanks
Update: After restarting my phone some 20 or more times, I was eventually able to see the list of networks and put the password in for the new network. So I at least have wifi now because my phone automatically connects.
However, all the problems stated above are still the same. I lose connection and cannot automatically reconnect when I go out and back into range of the signal, and can only regain the connection when I restart my phone and it automatically connects to the one known network on reboot.
If there's any information or anyway to try to fix it, I'd love to know.
Thanks

Wifi not working randomly

Hi,
I have a problem that my WiFi network disconnects and disappear from the list. Even if I search for network it will not show up.
It looks like a lot of the other WiFi networks around me is also missing when this is happening.
It will suddenly come back again and work as it should for several hours.
I have i locked to 2,4GHz, WiFi always on, scanning is on.
Had the same problem when I used Auto 2,4GHz/5GHz.
All other devices is working as they should. Have also reset the wireless router. (Netgear X4 R7500)
I have the same problem. When I turn the wifi off, and the back on again it discovers my router and connects.
Does anybody have a fix for this?
Same problem here. My 2,4ghz network sometimes just vanishes and shows up after a couple of minutes. And it just won't connect at all with my 5ghz network. My router is a D-link dir 868l. I'm on the latest firmware. My other devices all connect just fine, except for my 6p.
Updated to 6.0.1 and I have still problems. When I come back home, I need to turn off and on WiFi to reconnect. Wifi have not dropped since i updated to 6.0.1 yesterday.
Just curious
Who is your service provider? My girls 5x is connected to Sprint and she has no problems on my network. I have Tmobile on my 6p and it keeps dropping the wifi. Maybe its a Tmobile thing?
reset network config
I had the same problem and try to go to airplane mode on and off then even forget network and add back on. Work for a second and disconnected. So far this way work. Try this.
Got to Setting > Backup & reset > Network Settings reset
Hopefully this will work for you guys too.
Good luck! :good:
My brother has a Nexus 6p and the WiFi doesn't switch on at all after he updated to 6.0.1. I reflashed factory image of 6.0.1 again and it didn't work. I then flashed 6.0 but it still doesn't switch on. Any help?
bump
Anyone have a solution to this problem? I still have this big active, and have been using mobile data since.

"Failed to connect to network"

Lately I've been having serious trouble connecting to Wifi networks. This occurs both on my workplace network and home network. I have tried resetting my Network Config, but this didn't fix anything. The only thing I've found that will allow me to connect to Wifi is to restart the device - but I have to do this every time I want to connect to a different Wifi network than I was connected to previously.
One strange thing that happens with this is that when I disable Wifi - whether it be via quick settings or in settings - it doesn't actually disable Wifi. The toggle switches to off, but I'm still able to see nearby Wifi networks. The only way to fully disable Wifi is to enable Airplane Mode.
This has been happening recently since I performed a Factory Reset, flashed the latest factory image, and rooted.
Anyway, any help with this would be greatly appreciated!
UPDATE: Looks like switching from Automatic Wi-F- frequency band to 2.4 GHz fixes the issue, but that's not really ideal, as I prefer my 5 GHz network at home.

Wifi and 4G stuck together - how to fix this?

I know i'm not alone since i've seen this issue not only on my phone. When i'm at home my phone is mostly connected to wifi. My router is Linksys AC1900. Sometimes both the wifi and 4G icons appear together. when this happens my battery is draining like hell. a simple restart of the phone or the router is not a solution - i found that in order to make the 4G icon go away i need to first turn off the router so the phone is connected only to the mobile network, than i have to turn off both the data connection and wifi of the phone; than i need to go and clean the cache through the builtin recovery menu. the problem is that sometimes even performing all these things is not enough and the 4G icon won't go away. Download booster and Smart network switch are both turned off, but playing with them do not really affect the issue. also i tried connecting to both 2.4 or 5ghz wifi with no difference. i also tried setting a fixed IP address for my phone, but again this does not affect the issue. any ideas? i'm pretty certain that it's not a hardware issue since i've seen it happening to other people too. it's quite annoying since it's totally destroying the battery life of the phone and it seems that there's no real solution for this behavior.
What model number is your phone? Have you considered reflashing firmware / factory resetting the phone?
The model is 935f. I've tried reflashing with stock several times (the phone is not rooted) but after a while the problem comes back. This is the only issue I've had with this phone but it's quite annoying.
I've got the same issue. The only solution i've seen till now is to reflash with a custom rom.
Same
I have picked up the same type of issue. I did some snooping around and have found that if I have my mobile data on when in the streets and when I get home and I turn on my wifi, that if my wifi signal is very bad and my mobile data is on, then it would show both signals. It's as if the phone tries to get whatever data from both, since the wifi is so bad. I agree that it really chows the battery. The only fix I could get to work is to switch of the data and move closer to the wifi where it's the strongest. I will sit at the router for a minute or two, It then automatically removes the 4g sign and only works on wifi. If I stay where the wifi signal is bad and disable mobile, it stays there even though my data is off.
Did you do a factory reset and restore your phone to its original settings?
