[Q] Wifi won't connect all the sudden?

Hi, so here is my setup:
Darky's v8.0
Setirons 1.5.6
And Ive tried different modems, jk4, jl2, jl3
All of the sudden the other day, my phone stopped connecting to wifi. It will detect the network, then try to connect to it, then just stop and say "disconnected" and my wireless network will say either "remembered" or sometimes "disabled". Ive tried installing all 3 of the modems above, and each has the same problem, making me think it's something else. I also tried forgetting the network, rebooting, deleting the cahce, turning wifi on/off, data network on/off, and airplane mode on/off, and nothing helps. It was a really sporadic event and I've searched far and wide for a solution. Anyone have ideas?
this is what it does: I click "connect", it says connecting-disconnected. Split second change. Then it scans for a second, connecting-disconnected, it only takes a split second to change to disconnected.

I get this problem occasionally. Only thing that can fix it is a reboot.

Interesting, I have tried that. Is there any special trick the the reboot? As in... should wifi be on/off? do you have to "forget" the network before the reboot?

See if your phone can connect to another wifi point. That way you can rule out router issues. I have had issues with my router and wireless phones in the past.

I had that happen once.
I rebooted a few times, flashed two different modems, flashed Odin back to 2.1, then on to Cognition 3.03, and nothing...
...then I rebooted/reset my router.
*facepalm*

Well, I just tried to connect to a random secured network, threw in a random password, and it would sit on "obtaining IP address" then just switched to disconnected, scanning, and started the whole process over. I just moved, but the problem started before I moved, although I'm still using the same router now.

I'll try it again, but like I said, I did just move so my router was definitely reset. But, doing it once more couldnt hurt =]

I had that problem with cognition 2.3b8, then I flashed to perception and the problem went away. May want to try reflashing the original rom and see if the problem goes away.

I planned on flashing a new rom later today, so I will check it out then. It just seems weird, this has happened to me before and it just fixed itself after a couple days... There must be something specific causing it.
Also, I can use MobileAP just fine. I think its weird that I can create a wifi network but can't connect to one.

[Q] [AT&T] Wifi from hell, help?

So, before rooting, my One X had great Wifi connection. No issues. Now that I'm rooted, I can't connect to wifi to save my life. I tried the wifi fix (not the ROM, but the 3 files instead) and still nothing.
I've tried turning off Mobile Network while wifi was on, turning mobile network on while wifi was on, tried restarting the wifi....
I cannot get a connection to the Store, browsers won't open webpages, it's essentially done for. Yet every other device in my house can access the router just fine (and it's not just here, it's elsewhere.)
Anyone have any ideas how to fix this short of flashing the new ROM (which I can't do from my house since the HTC drivers always fail to install.)

Have you tried running fix permissions to see if there's some sort of error holding things up? The only other thing I could think to do is to do a factory restore of the phone, unfortunately...

Nexus 5 Wifi Issue

So I've had my Nexus 5 for roughly around a month and I hadn't experienced any issues others have had with wifi not connecting until now. My N5 will show im connected to my home wifi with full bars, but going into quick settings shows it to be orange. Suggesting there's no data transfer, I cannot use any internet based apps with wifi. I've tried some suggestions, switching my router off then on, rebooting the phone, turning some settings off in the advanced panel in wifi settings. All have failed.
I was just wondering if anyone else has this problem and if anyone has a fix to it.

There was a thread around here somewhere that suggested turning off your mobile data helped fix this problem, I think it was in the N5 General forums.....here it is:
http://forum.xda-developers.com/showthread.php?t=2550690
Don't know if it'll help or not, just saw your thread and had just looked at the other one, figured I'd toss it out there.

Thanks for the reply, just tried that solution but still no luck.

I have a similar problem except that there are phases of wifi not working.
Sometimes I would have around 20-30 seconds of WiFi not working and there would be no data transfer.
Speeds are still fast when it is working however.
I played a little with only using mobile data and no wifi, and everything worked. (Small sample size however).
Seems like this is a WiFi only issue.

So somehow overnight the wifi has managed to fix itself, will report back if the problem returns.

The issue with the wifi returned unfortunately.

Don't know if you've tried this but change your WiFi frequency band in advanced setting to either "5 GHz only" or "2.4 GHz only," whatever your router uses. Might be worth a try.

Thanks for the help, but I've tried changing some settings in advanced wifi settings but it hasn't worked. Even what you recommended I've tried that before and it didn't work.

wifi issue
Also I have the same issue - Im connected to router by wi-fi, home and work and time by time (5x a day) wifi stops working. Wifi is enabled in settings, but there is no connection. Restart the cellphone helps, but after that, maybe an hour, it appears again.
Issue was in 4.4 and still appers in 4.4.1.
Yet did not found how to solve it.

I have the same issue on my gnex running shiny 4.4, but I also had the same issue on 4.3. Tried the wifi options, nothing worked. Unfortunately, no solution for this device that has to last one more week. The double swipe down and tapping wifi gets the connection back, but it is only a work around.
The N5 connects seamlessly to my home and work wifi. A few days ago, I flashed the hammerhead factory image, TWRP and the 4.4.1 update.

Hey,
I have the same problem with 4.4.2.(factory rom, no root or not unlocked). Sometimes the wifi not works and get orange. I must put airplane mode to fix it. Its annoying.
But as well happens to me:
When I go out from office or home (where I have wifi connections saved in phone) the phone automatically switch to data plan from carrier. But when I come back the phone stays with data and there is not automatic switch to wifi. Sometimes it help to put wifi off or always airplane mode on/off for a while.
I do not know if it is normal behave of android but I would like have automatic switch to wifi.
I tried to change wifi details (changing bands, etc.) but not helped.
Please help. Thank you.

Is custom ROM or kernel will fix it??

For some unknown reason, as soon as I updated my router's firmware, the problem disappeared.

Updated Android 6.0 solved the issue

So I had the unfortunate experience of having my wifi go down while on vacation and for 3 weeks I spent a good chunk of time wiping and reinstalling multiple versions from Cyanogen, Paranoid android and 4.4 - 5.1 to no avail. I just did another factory wipe today and installed the new Android 6.0
The Finger Pointing Game is OVER
Read through 30+ pages of other android users with similar experience and some people send their units back to LG and some even managed getting a new handset. There was never any hardware issues with my unit I just couldn't turn on the WiFi but after the install WiFi works? Guess next time you push a software update to our Phones CHECK YOUR SH*T google and Maybe DON'T Take 3 months to FIX your F*CK Up.

I have a similar issue. Since Lollipop my phone almost never automatically connects to my WiFi anymore. What's wrong?

WiFi Connection Failure

Hi.
I only have one wifi network around atm. My N5 was working fine with it, and yesterday it started disconnecting from it.
Right now, when I try to connect, it connects for 3 or 4 seconds (it gets an IP address and actually connects to the Internet) before jumping back to data connection. When entering the Wireless menu on my phone it says "WiFi Connection Failure".
I thought I might have tweaked something I shouldn't (since also yesterday I installed Franco kernel and App Ops), so I went back to stock (using the Nexus Toolkit) and in the process I updated to the newest 5.1 release (I had LMY47D version and upgraded to LMY47I).
It didn't help. I also tried changing the router channel and security type to no avail.
Of course, I also tried to turn airplane mode on/off and forgetting network. And I just downgraded to LMY47D to see if that was the problem. But it didn't fix it.
I'm attaching the logcat. I hope I did it properly.
Any suggestions? Thanks!
UPDATE: I noticed it works in Safe Mode. I'll try to find which app is causing it.

I'm having exactly the same problem.
Updated to 5.1, after a run with Nike+ and Runkeeper, with GPS and Cellular Data on, battery drained and phone switched off. After a recharge, this problem emerged, different ROMs, different stock versions, different kernels. Nothing seems to make wi-fi work again.

OPO connects to WiFi, but no internet?

Hi all, thanks in advance for your help and comments.
I am running the latest cyanogen mod 13.0 snapshot. I just flashed it maybe 5 days ago and things seemed to be working just great. Today, I came home and when my phone connected to my WiFi network it said "Connected, No Internet." I tried connecting to another WiFi network that I have used, and got the same message. I know that the internet does work on the network because this laptop works, and other android devices I have are working too. I've tried disconnecting, reconnecting, rebooting, changing some settings. So far nothing has worked. Additionally, when I switch to LTE, it works sometimes, but stalls out quite a bit. Earlier today I was using LTE throughout the day with no problems. I'm pretty perplexed by this problem. Does anyone have any ideas what might be wrong? Thanks.

Did you clean flashed cm13 snapshot?

It could be an issue with the Wi-Fi channel frequencies; Try this fix, from Advanced WiFi settings make sure you have "Auto" selected under "Wi-Fi frequency band". Also, try creating a hotspot from your Laptop using your connection and see if the issue still persists. (For creating a hotspot you may use applications such as mhotspot etc.
Hope this helps.

Yeah it was a clean flash.

Thanks for the suggestions. I did switch between the 2 GHz, 5 GHz, and Auto options under the band settings. Never made a difference. I ended up clean flashing PA last night because I was getting so frustrated. WiFi works again, but the PA rom doesn't really have a lot of customization options. I'll have to try something else tonight I guess.
The weird thing about the WiFi issue was that it worked just fine for probably 4 days on the CM snapshot. I honestly don't know what could have changed. I didn't make any big changes to the ROM or anything.

Hmmm...i have the same problem about a week ago but i found out it got nothing to do with the rom but got a thing to do with the theme i used...it seems like the theme i use before doesn't work properly which prevent my wifi to work....i switched my theme and suddenly the wifi is working again....i'm not sure if this can help you but if you do use 3rd parties themes then i suggest you switched to default theme and try your wifi connection...
