[Q] Wifi Scanning Connecting Disconnected?

Seems like as soon as i rooted the phone it killed the wifi.....It detects networks but when i look at Wifi its jumping back n forth between scanning and connecting before it just rests at Disconnected...I wiped and switched roms even have the updated PRl and changed modems.....Same result....Any Ideas?

I have the same problem. Hopefully someone will see us floating way out here!

guys this has been discussed quite a few times in here... try this thread http://forum.xda-developers.com/showthread.php?t=1272226

That thread does not solve my issue....My Sleep Policy is already set to never........

And my wifi doesn't constantly scan.... it Scans for a couple of seconds...Saying its connecting but then just Says Disconnected....& keeps doing that same loop

It happened to me also I fixed it though, I downloaded the wrong kernel version did you root using this method? http://forum.xda-developers.com/showthread.php?t=1342728 if so then you probably just downloaded the wrong kernel version, so just download the one you should of and it should fix it. hope this helped!

[Q] GPS help

I downloaded fake gps on my a100 and set myself to monaco for a laugh....
big oops that was, now i can't get back home...
When I connect to mobile 3g or anyother wifi, the gps is fine, but at home on my hub, it allways sets me to monaco.... (wish i did live there!!!!)
I've deleted fake gps, and reset my hub.. nothing works. It must be linked to my wifi at home but how can I get it working again......
Thanks in advance....

Try this: go to settings > developer options > uncheck allow mock locations.
Sent from my A100 using Tapatalk 2

Done that. Even done a reset agps state.... nothing.... only reports wrong GPS state when at home..... annoying more than anything

On the market it says to disable the use wireless networks option in loction settings to avoid the issue you are having. Have you tried that?
Sent from my A100 using Tapatalk 2

Tried that, no joy. (or very very slow). Fake GPS obviously set something somewhere that needs to be reset. Grrrrrrr. Wifi GPS all ways worked fine before.... not a major problem this, just a tad annoying ....

Are you rooted? You could try deleting the files in data/GPS/...make a backup first of course

I am rooted. Cleared out /data/GPS and made no difference... still in Monaco.. ermmmm weird..

Try an app called faster fix, and reset your GPS pool it may trigger a re center on your location.
Tapatalked from my Galaxy S II.

Downloaded and run. Selected UK and hit go. Message at bottom says failure, please try again'

Try deleting your home wifi, rebooting, and re- adding your home wifi. It has to be something associated with your home wifi, since it works OK everywhere else. If that don't work, email the app dev.
Sent from my A100 using Tapatalk 2

I looked at the app in play store to get email address and noticed they have now put a warning on the description to make sure you disable use wifi for GPS before running to avoid problems.
Grrrrrr if only they had put that before I'd run it... others beware.
I have emailed them and will post reply.
Cheers anyway all.

Got it sorted. Original dev of app didn't help at all, just said look in forums....idiot.
I reset router, turned off wifi GPS and left tablet for 2 hours getting a GPS signal. I then turned on wifi and it worked..... oh well... cheers for help

Could somebody give me a link to or send me the GPS directory files. I will try deleting mine and copy the working once.
My GPS is still dead...not even a single sat after hours. I have tried the patch No2 now I am going to try the No1 Patch.

Hey filking - I had the same trouble as you with fake GPS and I've tried all the recommended steps you mentioned but to no avail.
Do you mind listing them out step by step what you did so I can make sure I'm doing the right fix?
Many thanks

Wifi connectivity issues

Hey all, I was hoping someone else has had this issue and has fixed it. I'm running a stock unrooted phone and when I connect to wifi, it connects to the AP and obtains an IP, but I cannot go out to any website or use any app that needs a connection (facebook app, etc). Things I've done:
Restarted phone
Factory reset phone
rebooted router
Tried other roms
Sent to samsung (they did a SW update) x2
Forgot the network, then reconnected
This is getting extremely frustrating as it's been this way since I've had it, but it got worse with the ICS update. Anything that anyone has tried and actually worked? The funny thing is, when you reflash the phone or do a factory reset, it works for about an hour then stops. Thanks in advance!

Have you ever connected that phone to a different wifi?
I encountered an issue a few months back where something went wonky and i had to completely reset my router and set it back up. Have you tried that too?
sent from my T989 full of CM awesomeness and a touch of Venom from the Darkside!!

Yes, I've tried different wifi AP's and none of them have worked, while others are on them including mine at home. I have not reset the router and reconfigured it because it's a cisco and as such is a pita. I have looked through my config and cannot find anything obvious. But still, others are able to connect just fine.

Same issue here. Never noticed it until recently. Reflashed LE1 and it worked for a couple of days. Going to flash the galaxy note modem tomorrow.

I know it's a shot in the dark, but some said it worked....
Try to disable the "UPnP" in your router.
Let us know....

premiatul: I can't find anything in my router for upnp. If anyone knows how to disable it in cisco ios 12.4(11)T1, I'll gladly try it.
Autx: please let me know how that goes and if it works. Thanks!

Is darkside wipe a temp or permanent fix, from what you've read?

Noone else has any info that may help? I would really like to get to the bottom of this. Devs: could this be a driver/kernel issue over a hw issue?

Honestly, whenever I'm running a TW based ROM I find that wifi takes awhile to connect. Any AOSP (CM/AOKP) for me is nearly instant.

Thanks for the heads up that the note radio didn't work. Also, the new official update didn't fix this issue either. Maybe I'll just have t-mo replace the device since it's not happening to everyone. Thanks all for your input!

Quick question.
Did you De-bloat your phone? Ie did you remove any apps from the system directory?

Not since the last time it returned from Samsung. And it's completely stock and unrooted right now.

I did a factory reset and the wifi came back steady for the past day I was slot more selective with my apps as I think this may have been the issue.

I'm glad this worked for you. I can't tell you how many factory resets I've done and it fails every time within a day. I bit the bullet and did a t-mo warranty exchange. Seeing as so few people actually have this problem, I'm chalking it up to my having bad luck and got a lemon. I hope the new one works fine.

I'd rather have a new one then the same one fixed lol

Home WiFi not working on E4GT

I obviously have the Sprint S2, and I continue to have issues staying connected to my home wifi. I have no problems connecting to other wifi networks. It will connect, then after a few minutes, it disconnects, even though it shows I'm still connected in my notification bar. I've searched high and low. It seems many other people are having the same issue, but no one seems to have a fix. Anyone here know of a solution? Thanks in advance.

So I finally figured out what the issue was. A lot of mobile devices have a hard time connecting to highly secured networks such as wpa2. If you have a wpa, or wpa2 protected router, you can only use numbered passwords. Up to 10 characters. I tried this, and it's the only solution I found. If that still doesn't work, change your wpa2 security to wpa, with a numbered password only.

Try changing the channel on the router, force it to a different frequency B or G only also.

if you have to use numbers and only 10 chars, it sounds like a router config issue. sounds like you have WEP on rather than WPAx

Wifi busted
I actually have the same issue. Wifi worked flawlessly on gb. On ics every time phone goes to sleep it drops, notification says connected. Toggle wifi off and back on works, phone sleep back off. Tried wifi never, only when plugged in. Switched to 2.4 ghz only tried 5 ghz , too. Linksys ea4500 wpa2/aes(setting) brand new. None of the numerous other devices in the house have any issues. Speeds seem awesome.
Tried factory reset nothing works. Even got sprint to get me a new phone, still no solution other than going back to el29. Currently, running fi03 stock rooted. Scared to try latest fi25. Any other suggestions would be great.

still sounds like a router compatibility issue. See if it happens on a different wifi.

The only way i can successfully stay connected is if there is no security or wep is used. Same router nothing had changed. Again worked flawlessly with EL29 update comes to FF18 and it no longer works. Sprint has said it is a known issue with ics on samsung and htc but no fix. Don't want to give up my security just to use wifi. If i roll back to gb everything works again without changing anything in the router. So i don't believe that is it. Plus, i know all about router settings not a noob. I beleive it to be something in the phone update.

My wife runs fully stock newest release and its fine. Try a different router. routers can have compatibility issues with devices. Also you say "its a known issue" but can you give a source?
I'm not saying its router settings. I'm saying it can be a compatibility issue between router and phone chipset.

I was having this issue on fi03 and fi25. Tried different modems, kernels, routers with no improvement. Downloaded WiFi keep alive from the market and use workaround #1 and it hasn't been an issue. Doesn't answer the question but it does solve the problem. Hope it helps. Good luck

I guess i should've mentioned there are 2 of the same phone in the house. Wifi works fine on the other device. Source? As in sprint tech support told me over the phone it was a known issue with samsung and htc devices, not all are affected. This is why sprint decided to replace my old non working phone for the new one.
Not sure why of it were truly a setting inside the router why would one work but not the other? Seems highly improbable to me, just saying. I do appreciate the feedback though.

So two of the same phones. One connects and one doesn't. Interesting. About the tech, seems a pretty wide declaration of an issue. samsung and htc phones. lol. There are a ton of those and its a 'known issue'. If it were a known issue, they would have it tied to a specific phone and wouldn't say 'well err um some phones work and some dont'. lol. Anyway, I don't usually trust those techs.
Back to the issue. If one works and one doesn't... Then it sounds software or still compatibility type issue.
Have you tried these things? If it were me, this what i'd try....
1) I'd reflash your phone's ROM fresh and try again. Full wipe. It's possible the update boinked your wpa_supplicant settings.
2) DHCP: stick a static IP on your android and see what happens. (dont confuse this with a static dhcp lease) DHCP does some interesting things on android phones as far as wakelocks and such.
3) In the router, turn off all the bell and whistle crap... Some of these routers have things like 'afterburner' and things like that. It can cause issues at times. Keep track of what you turn off and obviously if it don't work, turn it back on again.
EDIT:
This is interesting as well. Your not the only one.
http://forum.xda-developers.com/showthread.php?t=1847889&page=4
Try the things I posted but ultimately, you may need to just flash a different ROM version... Doesn't mean you need to go all the way back to EL26. At least you know its not only you...

So I initially called Centurylink, and they told me to change security settings. I did this, and it worked for a short period, but then dropped again. I couldn't figure out why this kept happening, and it had become quite frustrating. Then I realized that I had created a new network with a personalized name and password. My laptops connect fine to that network, but my phone won't, so I connected to the initial network created by Centurylink, and have had no issues. So I can suggest trying that as well. Hope that helps

Same issue for me too, since moving from gb. Running S710.10 S.FI27
I see this on both of the WIFI networks I connect with regularly. Home is worse. Every other device at home, including phones, PCs, TVs, tablets: mine and guests, can connect and stay connected just fine. My Epic 4g with ICS can't stay connected to save it's life.
I'm about ready to try the less complex key route, but not my 1st choice. Any other ideas?

different rom? mine never ever disconnects running cm10.

Set up both home networks using WPA/WPA2-PSK and no issues. Did have issues at work with WEP so perhaps that's the offending solution? If so try TKIP instead.

Need Some Major Help Please

I have had my Galaxy Nexus for just over a year and have been running MMuzzy's version of Android 4.3 since July 30th. Just today, my phone stopped connecting to my home router, and I have literally tried everything to fix the Wi-Fi connection. First I did the simple stuff like restarting the phone and putting it into airplane mode. Then, I tried forgetting the network and re-entering the password, and wiped the cache and the delvik cache. Finally, I reverted back to Android 4.2.2 with a clean install, but I still don't have a working Wi-fi connection.
When I click on the profile, it barely flashes "connecting" and just reverts to "Saved, secured..." I know that this is not a router issue since my laptop, roommate's phones and laptops, and my girlfriend's phone all work fine.
Does anyone have any suggestions at all? I'm worried that my phone is done-zo.

Have you tried connecting to another wifi network with your phone? You could also try to create a wifi hotspot on another mobile device and connect to it. If both works then you know at least that your GNex' wifi hardware isn't broken.

Total shot in the dark, bur have you updated the ROM to a new version? Maybe the dev implemented a kernel or some change to the kernel that caused wifi problems for you.

Upon waking up, my phone once again reconnected to my Wi-Fi. Totally bizarre, but 4.3 has been a complete crap shoot so far. Thanks for the replies, much appreciated!

probably you only had to reboot your router..something was wrong assigning the ip address to your nexus

Or DHCP pool was full.. Meh. Boring thread.
