WiFi connect loop on WPA/WPA2 PSK

FIXED:
Apparently the router had a reset button which I just dicovered hidden between the vent gaps, which has a different function than just pulling out the power cord for a minute or so. Now WiFi is working on my phone.
My phone won't connect to a WPA/WPA2 PSK WiFi network. It previously was able to connect (for 2 weeks), but since 6 weeks, it loops: scanning, connecting, disconnected. I have flashed many ROM versions and wiped all phone memory since (mainly for other purposes than this problem), but it still won't connect.
I have tried resetting the router several times without result. I can't access any more settings, because I live with other students in a house where the house-keeper also lives.
The WiFi at my university (802.1x EAP) and the WiFi at my parents house (also WPA/WPA2 PSK) always works properly.
I have searched through the internet and through XDA-forums, but none of the proposed solutions works, can be done on my phone or I am not able to try them because I can't access the router settings.

How about different kernels?

I have the same problem. After unlocking bootloader/rooting my Arc it doesnt connect with my router anymore. My other "still locked/unrooted" Arc has no problem connecting to the router...
edit: seems my BT is having problems aswell.. couldnt connect/find any other devices

I'm running stock 2.3.4 with stock kernel. DoomKernel still has problems isn't it? I'll have to live with it till that's fixed. Already tried reverse tethering, maybe that will work.
It's not such a big problem, as I have my laptop near me there, but installing apps is quite a hassle this way (search for .apk, install apk with flashtool or move apk to sd and install).
I don't have a data plan, it's €10/month for 200mb, pointless for me, because there's WiFi at home, at my university and in the train.

So why did it work before? Does resetting the route solve the problem, I could just try it again...?

When you restoring your phone and after that making setup, then dont log into your google account. Install freshly new rom and directly try connect wifi. If i remember right i had to thiskind problem. And after i realized that problem was "google settings and thatkind stuff backup restore". I just uncheck this option and after that i was abel connect my home wifi. Before that i cant. give a try

Also didn't work, tried that the last time I reflashed.
Anyway, fixed it just a few minutes ago: apparently the router had a reset button, which has a different function than just pulling out the power cord for a minute or so. Now WiFi is working on my phone.

it was to easy. Case closed!

I am using recently acquired Xperia Pro. I get very weak wifi signals in my room so i bought a Thomson Wifi Repeater/Access point to extend the wifi signal to my room. My phone is now unable to connect to the wifi and keeps scanning, connecting and disconnecting. It eventually ends up with a Limited Connectivity noticfication meaning i am unable to connect to internet although get full wifi signal strength. I tried changing some IP configurations but it hasn't helped. Interestingly my Notebook PC is able to connect and maintain somewhat stable connectivity, although at times it too gets disconnected from the internet. I tried connecting to the Wifi using an iPhone and it too had the same issues i.e able to detect the wifi signal but unable to connect to internet.
I am still trying to find the solution to the problem and will update if i find a way out.

I suggest that you update both your phone software and the router firmware to latest possible version.
Let me know how it goes.

same problem
I have the same problem on my arc s after i downgraded the official ICS to gengerbread using flashtool i even tried to upgrade back the ICS but the problem hasn't been fixed

Fixed
Try to find setting on your router like "max number of peers" or something like that and change the value to maximum it can, maybe it will tell the maximum number. After that reconnect your phone wifi, and bless me:angel:

Had same wifi diconnect loop problem - solved
I had the same WiFi loop - connect/disconnect issue. Extremely disturbing.
It appeared out of nowhere.
Rebooted the phone and the router several times - no help.
Used WiFi analizer to check for interferring chanels - nothing special.
Changed the WiFi chanel anyhow - no help.
Reinstalled/uninstalled AT&T smart WiFi - no help
Removed my WIFi network ('forget' button) and found it again, including the password - no help.
I have the WiFi manager installed, but I sort of forgot to check it doing everything through settings.
Only then I found that my WiFi Manager is stuck on the update announcement screen.
Okayed it - problem solved.
Funny thing, I don't remember updating the WiFi manager lately.
Feel so stupid wasting 2 hours.

[SOLVED] WiFi Can't Obtain IP Address on AOKP

Hello, I've been having a problem with wifi on all new 4.2 roms over the last week or so. For an unknown reason, I can connect with phone data but attempts to get on wifi have been mostly unsuccessful. WiFi just says "obtaining IP address" but eventually times out and starts authenticating again. I have tried wiping everything with 3 different roms and now I'm on Tasks AOKP rom (12/23 with stock kernel) and having the same problem. I've tried all available Canadian modems with the same results (data is best for me on LLH1 though). If I switch back to CM10 (12/16) my wifi works perfectly.
I can get wifi if I mash the on off a few times as it usually causes a force reboot and when it boots I get wifi about 50% of the time. Attempts to modify router settings and reboot my hardware have been futile.
Anyway, I'm hoping one of you is interested enough to peruse the log I saved using "wlan" as a filter. I don't know if that's the best filter but it seemed to show the gist of it. Thank you in advance!

I'm having the same issue task aokp 12/23. Also, if I try to toggle the wifi in the settings screen, it reboots the phone.
However you might try to do this. This morning, I flashed the 12/23 kernal found in task's op. I can toggle wifi on/off now without issue. But i'm not anywhere near wifi to check if it connects.

I found WiFi at target and I'm posting from it. It connected right away.
So, flashing the kernel alone after flashing the ROM, fixed my problem

If you were having the same problem as me, I have to wonder if disconnecting and attempting to reconnect will work.
I downloaded tasks 12/23 underwear kernel, booted to recovery, wiped cache/davlik, flashed only kernel, wiped cache/davlik and rebooted. Tried toggling wifi a dozen times, phone crashed, rebooted, still can't get IP. I imagine that if I play with it long enough I'll get wifi back temporarily, but I use wifi more than data so I'd like it to work better if it can.

Back at home, I can't connect to wifi.
Edit. randomly tried it again, and it connected instantly.

Yeah. I've spent a lot of time troubleshooting router settings (channels, signal type etc) and have thought on several occasions that I had fixed it, but shortly after found that it was a one time connect. I have a spare router in storage that I'm going to try, soon, and that should help me decide if it's a router problem or a JB issue.

Well, no need to play with the router I have managed to obtain flawless wifi, but not on Tasks rom. The 12/27 illusion rom works great, but I can't get mobile data working on it. I switched back to tasks with hope that a future update sets the wifi straight.
Sent from my SGH-I747M on Bell using Tapatalk 2

I tried the official CM10.1 12/28 nightly this morning and quickly discovered that wifi was working great. I was able to turn it on/off multiple times and reboot without issue. I flashed a different Canadian modem and reflashed tasks AOKP rom (no kernel, no gapps) and wifi was broken again. That logcat makes me think it's something to do with how the rom is handling DHCP requests, but I'm a noob and hardly know anything about any of this stuff.
A nan restore to my AOKP rom got all my stuff back, but it's takes me a solid 30 minutes to get wifi connected.
Sent from my SGH-I747M on Bell using Tapatalk 2

I updated to tasks AOKP 1/1/13 and my wifi is working perfectly! I considered switching back to 12/12/23 to see if it was the build, but who cares?!
This issue is resolved.

Note II Sleep Mode Wifi Drop Problem

Hi everyboby,
I'm an old android, but also newbie Galaxy Note II user. At the end of my two days experience I observed that wifi drops out when after ~ 10-25 minutes the phone entered the sleep mode. I tried factory reset, changing wifi channel on router, changing wifi encryption mode but its didn't work. After that, i'm trying disable mobile data and wifi issue has gone. What could have caused this? A hardware problem or sofware oriented? Or an incompatibility issue between phone and router?
I'm also tried another wifi in the another location and i never faced that problem. But all the devices in my house can connect smoothly to the router.
I'm installing wifi fixer app from play. I tried with that app.

I didn't work unfortunately. When i exit sleep mode, app repaired wifi connection resetting wifi connection. But it means when the phone in sleep mode wifi has not been transfered data.

Open wifi in settings.
Then click menu and select advanced.
Then tick keep on during sleep.

Kit Kat (Stock) Data issues

My phone seems to do this all too often on a daily basis. I check that I have no received emails, tweets, facebook notifications, etc. The problem is my data uplink arrow keeps flashing and it hangs there. This is usually remedied by putting my phone in Airplane mode and switching back it usually works but there have been times when I have empty bars with no data nothing, but it can be fixed by switching mobile network types from WCDA/GSM back to LTE. Anyway this can be fixed, or this actually a Kit Kat issue with the Note 3?
I'm on Stock Kit Kat Unrooted (unfortunately) because I updated before wanting to root and now I don't want to trip KNOX. I have also run a factory reset on my phone (through the bootloader) but it didn't fix the problem.
Is anybody else having this trouble with their Note 3?

I have this issue too. I'm rooted on Darthstalker v6. It happens daily. I just toggle airplane mode on and off and wait ten seconds. I've reinstalled this rom twice and the issue is still there. Hopefully someone can help.

Same issue here! Stock, unrooted. Must be a kit kat issue, I don't remember having it on jelly bean.
Anyone else with the same issue? Chime in
Sent from my SM-N900T using xda app-developers app

Yup.....been noticing this happen too.....was hoping it was a tower issue soon to be resolved....starting to not sound that way....blah
P.S just started happening (or me noticing it) in the last 2 or so weeks

It's a known bug in android 4.4.2. The new update 4.4.3 has a frequent data connection dropout fix in the change log. Hopefully we get some leak or something for it soon. Now that the s5 is out.
Sent from my SM-N900T using Tapatalk

I didn't notice the data drop out until I tried a KitKat rom. When I restored back to the jellybean rom I was using the data drop out continued. So I ended up wiping and flashing the same jellybean rom and still notice the data drop outs.
Sent from my SM-N900T using xda app-developers app

I have the same issue from the last 4.4.2 update, when the phone is in standby for long time the data connection drop out, or time in time the phone scan the network and some time back to normal after some second or keep scanning and need reboot. when I check the network mode I found all option unselected, I select lte mode and the phone do not respond and have to reboot. I reinstalled 4.4.2 with kie and Odin but same issue . Samsung representative told me that the issue is from T-Mobile , that the phone is ok, and T-Mobile told me that the issue coming with the update from Samsung and affected to note 3 and s4. Who has the fault? my temporal free solution until the next update was replace the sim card in the T-Mobile store. I did yesterday and until now the phone have been ok with the data connection up all time. when it scan the network back to normal with not data drop out.
Last thing, go to wifi - advance option and I put disable (keep wifi on during sleep) and (always allow scanning) maybe these can avoid the scan the network time to time.

[Q] Major WiFi issue out of nowhere?

Hey all. I need some advice. This morning my G3 (D850) dropped WiFi connection for no reason. It says the signal is good but the network info says saved, secured. It will attempt to connect over and over again and if it does connect the signal is weak as can be and it drops the connection within 2 seconds. My coworker has a G3 also and is connected to the same work network I am. His connection says excellent where as mine said good. His device connects just fine with full bars. I'm baffled. I've already tried manually selecting 2.4 Ghz and 5 Ghz instead of auto select and that didn't help at all. I've tried manually turning off WiFi and turning it back on. I've tried turning airplane mode on and then off to refresh the connection and that didn't help. I've done a battery pull as someone in one of the android authority forums suggested that (apparently I am not the only one having this issue.), didn't work. I've unchecked WiFi optimization - no dice. There was another post on a different forum here on XDA that said turning off WiFi and then deleting the WiFi config folder located in data/etc/wifi and then rebooting fixed the issue for them so I tried that. After reboot when I tried to turn on WiFi my G3 rebooted itself. Does it everytime. SO, I had to restore to a nandroid backup (btw I'm on rooted stock 10f) to get the phone to stop hating my WiFi toggle attempts. Last ditch effort I did a factory reset hoping for an easy fix... Nope. I don't know what else to try. It was fine yesterday all day. This morning it was perfectly fine and then randomly started having this issue. I haven't altered any system files whatsoever. I really don't want to send my device to LG for warranty replacement so I'm hoping someone can help me out that may have had this issue and resolved it. The only difference between my device and my coworkers device is he is still on 10d and I am on 10f. That could be the issue I guess but that doesn't really explain why my device has been perfectly fine until this morning and I've been on rooted 10f for weeks. I am planning on flashing back to straight bone factory stock 10d when I get home here in a few hours from work but Idk if that will help or not. Judging from the amount of google search results of "LG G3 WiFi connection problems" this seems to be an issue for several people. I won't know if it's on the software side or hardware side until I get home but in the meantime has anyone had these issues at all? People have had success in changing to Static IP but I would have to do that for every connection I attempt to connect to and that's a pain in the a$$. Also, that does nothing to identify the root cause of the issue. Any help would be greatly appreciated. =)

Thanks for the reply. So it turned out my phone just randomly decided it doesn't like my work network anymore. Idk why lol. I got home and it hooked right into WiFi. Gf's WiFi and open networks as well. I call shenanigans. I went ahead and flashed back to 10d anyway though.

I am having the same issue! But it is happening in other networks too...sometimes I get the phone to connect but it only works for a while and when I check the networks it only says Saved, even if I try to connect again

Having the same issue, whether at work or home, my wifi has become near useless. I've even gone as far as trying a different ROM. Didn't work.

Same thing here

I also have tried factory reset, installed a new ROM, changed settings in my router... but the problem remains I don't know what to do anymore, I use wifi a lot!! I searched through other topics but no one seem to know how to solve it. Unfortunately my warranty already expired, I took my phone to some technicians but honestly it didn't help at all...they all said it was a software bug and I should wait for an update but if it was just that a new ROM would fix it,right?
I am not very familiar with phone hardware but I assume that if it was a hardware problem I wouldn't be able to turn it on or connect to any network, right?? (any experts here???)
Any solution is welcomed.

anyone please?? :crying:
P.S : I tried a new baseband, new kernel and new ROMs. So far, nothing changed.
I can connect sometimes but get kicked out within minutes. At other times I only get the saved,secured message.
This is happening in every network
