Wifi problem just reared its ugly head after 48 hours with official Froyo

I may have bragged too soon on good ol' official Froyo. I had a smooth install and the only problem I've noticed is the messed up Quick Office deal like most others. Today I just had another problem start.
I've been using my secured home wifi network fine, but for some reason the Captivate will no longer connect to it. I've tried doing a battery pull, turning the phone off and back on, and even completely removing the home network from the list and then putting it back in. I'm sure the password is correct. It just sits there, saying "Obtaining IP address". It retries several attempts, and eventually gives up and lists my home network in the list as "Disabled"
This is significant suckage!

I had similar problem try unplugging router and plugging back in

Bless your heart! That did it! I just read on the AT&T forums that someone else had the exact same problem and he did a factory reset of his phone which fixed it. I was hoping I wouldn't have to go there

I found an easy solution to the problem. Open Allshare, then you should be good to go.

After opening Allshare, hit connect.

Yes sometimes power cycling the router is all that is needed. I notice this with laptop sometimes too.

Yeah that was me...
I tried everything else before the factory reset, but the reset fixed it, now I've got wi-fi with no problems

If you do a factory reset, I realize you have to reinstall all your apps, but what about the ones I paid for? Will I have to purchase those again? I'm thinking of doing one just because I think it will smooth things out and get rid of a couple of weird quirks like the Quick Office icon problem.

anything you purchase with your google account is tied to your google account. you dont have to re-buy those...for any phone that you log into your google account.

Has anyone tried my fix? Sure beats having tofactory reset...I'm just sayin.

It works, but you have to do it every time, so it's more of a workaround than a fix.

I had an issue with connecting to one of my work wifi routers (would just sit there saying 'obtaining IP address' but never would connect) and could not fix it until I tried using "FXR WiFi Fix and rescue" app from the market. Free app, will erase ALL of your saved WiFi data so make sure you have your passwords for encrypted networks, but this fixed it with one click and a reboot. Seems to connect faster to the networks now as well. I had a similar problem after the previous update that went out OTA and had to reset the phone for that one.

I thought about trying this app, as my wifi issue returned today. I thought I had gotten rid of it by doing the factory reset, but alas it's back. I'm really contemplating a custom ROM more and more every day. I just don't know which one to go with that will provide everything I need. This app sure asks for a lot of permissions, so I'm sort of leary about istalling it.

Welp, I bit the bullet and tried the FXR app. No dice for me. I'm waiting for the wife to get done surfing so I can try a router power cycle. If that doesn't work, I'm looking at my second factory reset in less than a week. Froyo, you suck! I never had wifi issues until I upgraded to 2.2. What I can't understand is, why some of my issues are better, yet some are worse. Is it that difficult for these idiots to figure it out?

Just going to throw something out there, that I noticed yesterday. I'm on a custom ROM, but I noticed some pretty flaky results to my wifi, but only when I was using the modified TouchWiz launcher. The wifi had trouble connecting, and wouldn't sleep. The notification dropdown widget wouldn't control it. Then I switched to Go Launcher EX, and the behavior stopped.
Check another launcher, and see if that makes a difference. Sure, it's a longshot, but I'll be interested to see if the stock TW has the same issue as the modded version.

I was having the same wifi problem after updating firmware to official 2.2 kb1. I used fxr and now wifi connection works great.

Wifi connection connected but won't load pages

It said connected in the wifi setting and it shows bars but it just won't load any website in the browser .. anyone got a fix for this?

I have the same issue. Tried different combinations of restarting wifi, turning on/off cell data, on/off wifi calling, etc... all with no result. I've also tried on different networks (both public and private)-- it'd start working for a while and then all of a sudden stop and never work again.
Seems similar to the problem here: forums. t-mobile.c om/t5/T-Mobile-G2x/G2x-WiFi-DNS-issue-not-the-4G-switching-one/m-p/831439 (sorry there's a new user no link restriction)
Does anyone have any suggestions?
Thanks

is it specific to the browser or can you not move any data?
Idk, whenever I have had problems connecting to the tmo network, which is a separate issue.. it was always that wifi calling was still on even tho wifi was turned off. Every time I had probs w/ data on tmo network, it's been wifi calling.. Your case seems to be diff tho.
Is it specific to just your network or all other networks? Try shutting off wifi, reboot... then turn it on again? Idk.. just tossing out ideas.

Some found the root cause and I am posting his finding as I do have the same issue and can reproduce the error:
I think I have discovered a new WiFi-related bug in the G2x's software. I have witnessed this occurring on my phone, and have also reproduced it on a store demo unit. I believe it is unrelated to the switching-to-4G problem people are having with the My Account app, since it occurs even if I have set up the Google account on first boot after a factory reset.
The details of the problem are:
- Every so often, the phone randomly gets stuck in a state where it is not able to initiate any new connections that are made using a DNS name. Attempting to navigate to a web site, h**p://w*w.google.c*m for example, will result in a generic failure message.
- However, attempting to connect directly to an IP address instead of a DNS name works perfectly. For example, navigating to 74.125.225.16 will work fine and will load the Google home page.
- When the phone is in this state, using a DNS lookup tool such as "DNS Lookup" from the Marketplace *will* work, even when using the default DNS server address that the DHCP server is giving the phone.
- The problem has occurred for me when data is off and WiFi is on. I do not know if data being off is a requirement, since this is the way I usually run the phone, so this may be coincidental.
- Switching WiFi off and back on again will *sometimes* work to solve the problem, but sometimes will not. When this doesn't work, switching WiFi off, then switching data on, then back off again, and then finally switching WiFi back on again will occasionally correct the problem. However, I have seen situations where none of these things worked, and the only way to get DNS working again was to factory reset the phone.
- I haven't figured out the exact pattern yet, but this issue seems to occur when the phone has been inactive for a certain period of time. I have often discovered that the phone is in this state upon waking up in the morning after leaving the phone on the charger overnight.
- I have, however, found a method to reproduce the problem that seems to work fairly consistently:
1. Turn WiFi on, and data off.
2. Power cycle the phone.
3. When the phone starts up, start the browser and attempt to browse to w*w.google.c*m. It should fail.
4. Try to browse to 74.125.225.16. It should work.
Just wanted to get this issue in the forums to see how many others have been noticing the same thing.

I know that once the device has less than 10% battery it automatically turns the WiFi off to save battery power. Were the devices this was happening on have a low battery?

Fully charged. It even happens when pluged in with the charger.

My Wifi wouldn't even work if I froze it with Bloat Freezer. It has to run in the background for wifi to work. I found that Wifi can get really inconsistent with it disabled.

Same problem here. After about 30 minutes of being idle, as soon as I pick up the phone it tries to connect 2g/4g. The log are saying theres no connection, so it appears that wifi its going to sleep and not waking up so android is trying to connect 2g/4g
Really starting to be a pain
I have frozen the bloat, and I think the problem is getting worse.
Toggle airplane mode is a quick workaround to get wifi to wake up

Same thing happened to me, I did 2 factory resets, and it seems it has been fixed, don't really know what causes it.

This may or may not be related, but...
It looks like I found a hacky fix for the dns/wifi/4g bug: install "Set DNS" from the market.
Now when I go into market, and display my downloaded apps, it jumps from wifi to 4g then back to wifi as it should, fast.
Whether or not it should even do go to 4g is debatable, all I can say is my 2 Galaxy Tabs had the same behavior.
If everyones connectivity issues are really due to the DNS settings getting wiped out, then this will work around the problem until I/we find the location of the actual bug.

Would you guys having this problem also post it here?
http://www.lgforum.com/forum/boards/general/lg/topics/g2x-wifi-problems
Thanks.
I figure the more people that post there, the more the chances are of LG fixing it quickly.

Work around:
enable airplane mode
reboot
enable wifi
wait a few seconds after the wifi connects, background crap stops
disable airplane mode.
The set dns app looks like a winner. Haven't tried it but that's what's
wrong.
The freezing and other suggestions are all useless crap.

Updates...
I did a factory reset and installed JuiceDefender (I don't know which one worked) but it seems to be all fine now... will update if things become problematic again

I've been having this problem as well. I've always been able to fix it by toggling WiFi off and back on again. I downloaded SetDNS and when it happened again last night I tried that and it worked great.
Glad to see it's a software problem and not a hardware problem.

same problem here. hopefully it won't happen in cyanogen mod

This fixed the problem, at least until the next time I reboot my phone

How do you use SetDNS? This software bug in G2X reboots my router (DGL-4500) sometimes.

Question bout SetDNS app
Does the phone have to be rooted to use the setdns app? I try to use it but it says "Cannot get root. App will not function."

[Q] Data connection stops when in sleep/idle.

Since I upgraded to Jellybean I have a problem with my data connection while my phone is idle.
This disconnecting of data only happens when I use my Data, and not with WI-FI.
When I don't touch my phone for about 15-30 minutes, I won't recieve any push-messages (Whatsapp).
I searched for this problem, and do believe the problem lies with the idleing.
When my phone is idle I think my Data will shut down and will only reconnect when I wake my screen.
Sometimes it will recieve the messages at random moments, maybe when the data gets refreshed.
This makes my phone pretty much unusable, because I want to recieve my messages when I need them.
Does anybody know a fix or a ROM where this "data sleep" is disabled?

Hi!
I was about to post kind of the same question about phone idle!
I am experiencing the same problem when my phone goes to idle!
I also loose the wifi when phone screen is off...
Everytime i wake the phone, i dont see the wifi signal... then, after maybe 2 sec, wifi (or mobile data) is connecting, and i recieve mails & things...
I think that's why i have a bigger battery life in JB instead of ICS ...
I experienced this bug with a few ROMs, il PA, TSM, CNA, etc... (stock or custom kernel...)
Any help will be welcome...

I've tried lots of roms and kernels, including GB, ICS, JB. I also tried different radio's (for i9023). I did a full wipe for every Rom install.
I don't have any problems using wifi, so I think your problem is different.
I use WhatsApp Messenger. When my phone is in sleep mode, I can't get any messages when using data connection. No problems on wifi so far. I followed this faq for WhatsApp problems. It's still not working properly.
I'm starting to think it's hardware related. Any help is appreciated.

I think I've got the same problem. Since I've flashed Androxide JB, my phone isn't syncing on data. I did revert to ICS, but it didn't help.
On wifi, background sync is working fine.
I tried different carriers, roms, radio, kernel. All of them didn't work.
Any solution available?

I also experienced this problem after flashing Androxide JB. Different SIM card doesn't work either.

I am also having this problem. Have install slim bean 3.0. connection seems to drop when the phone goes idle. anyone found a fix?

In settings, go WIFI, hit menu soft key, advanced and there should be a menu called "Keep Wi-Fi on during sleep", click it and set your choice.

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?

Are you also facing this Lillipop WiFi bug ?

After getting N5 updated to the 5.1 update whenever my phone goes into deep sleep the WIFI turns off (yes I have checked the option to keep WIFI on during sleep). But it's really frustrating as I cant get any update on my mails and on messengers. Tried 5.1.1 custom roms, they are also facing the same problems. Are you also facing this problem ?

Nope, never

I would check your router, I remember a year ago my router started kicking off people for no reason on WiFi.
Found out it wasn't the devices but the router itself so I replaced it after seeing it was faulty even after a reset and now those devices were working fine.
So check your router's firmware, try a power cycle and whatnot.
