No wifi after 2.2 upgrade

So I have done the official 2.2 upgrade but now my wifi isn't working. I have gone into software updates and updated the profile, prl, and checked for new software and firmware.
Wifi keeps saying "obtaining ip address". It's my home wifi and before the update it was working flawlessly.
Appreciate the help.

Do I have this posted in the wrong section, or has this question been answered? I've searched high and low.

Try reflashing newest radio and wimax. Flash one at a time. This has happen to me before with wifi and 4g but on 1. 47. If that does not work flash calklins v1. 02 rom. I am using that on wifi typing thos response. Good luck

from the sound of it he flashed the official OTA so probably isnt rooted.
Have you tried it with any other routers to see if it connects?
try unplugging yor router and re plugging it back in to reset it and try connecting if that doesnt work sounds like your radio is messed up and you may have to take ti to a sprint store so they can reflash it if you arent rooted.

I am using the router for my laptop right now so I dont think the router is the problem.
I had the unofficial .3 update which is when my wifi stopped working, then I upgraded with the fix to .6 last night, still no wifi. I am not root, just bone stock .6 froyo...

Take it to sprint service center. Or delete the wifi settings in the phone and reconnect.

The reason i suggest resetting the router is because they often store information about a MAC address, When the information changes sometimes routers have connection issues. you dont see it a lot and since most of the time the information doesnt change (you dont update much on your pcs that would cause this). When it does change (ie a radio from a phone) it can sometimes cause issues. that's why i suggested you restart the router. I have had it happen several times when changing radios on my phones over the years.
Just because 1 thing connects to a router does not mean it cant contribute to another thing not connecting to it. I also wouldnt bet my life that it would fix it or anything.i was just giving a suggestion that HAS worked for me in the past when similar issues happened.IT was a good place to start. It would also help verify the problem is in deed with the phone from an actual tech point stand instead of an assumption.
anyway best of luck with getting this fixed

Gave it a shot, but still no luck. Keeps on trying to obtain IP address. Won't connect at my friends house anymore either.

it is definatly the phone then. It sounds like thw Wimax radio didnt flash right. With out Root i think your best bet is to drop by a sprint store they should be able to reflash it for you.

@chris17house
I have the same issue on my EVO that is still on 1.47.
The first time I connected my router gives my phone a lease for a ip address (lets say 192.168.0.010) and associates it with the mac address of my phone.
When I try to reconnect at a later time, the lease for my phone on the router has not expired, but the router gives my phone a new ip address (let say 192.168.0.020), which causes a conflict with the same mac address, but two different ip address. Once I reset my router and my phone the problem is fixed, because the router releases the lease and my phone does a dns flush.

Do you think flashing the wimax or radio instead of reflashing the entire rom would be worth a try? And if so, where is that file located please.

Ok, so wifi connects everywhere except my home. I have unplugged the router and modem for an hour and reconnected them. I still am unable to connect to my home wifi. Is there something more i need to be doing?

I was having the same problem with work and home, but all I did was forget both locatations and discover them again.

[Q] How do you spell headache? DI18 EB13 EC05

Odin a refurbished phone to ReRFS Format Stock ROM EC05.
The wifi will connect to my router but I get no data.
Sprint says to return the phone.
Could it be that I didn't consider if I was coming from DI18 or EB13 or if it was even EC05.
Maybe the modem just needs to be updated.
I really need advice, because I do NOT want to send the phone back unless the hardware is truly defective. What should I do?

Odin the DI18 stock, it will immediately start downloading the EC05 OTA. WHile it is downloading check your wifi in DI18. If it works there, then install the EC05 when it is done and check it again. If it don't work in DI18 it probably won't in EC05 and may be defective. Check it with a public wifi like McDonald's to make sure it is not an IP address conflict or something.

Okay...
Okay. Just did that.
Same problem.
3g is busy downloading what I presume is the ota update.
I did go to a sprint sales point (in the mall... not a full blown sprint store) where I was able to connect to wifi and get data.
I do connect to my isp with a static ip configuration.
Is this my problem? If so, how do I fix it?

Uncheck the static ip box and rescan. Reboot your modem and router and the phone should connect. If you need to use a static IP also put in the DNS server address. You should be able to get that info by running ipconfig on your computer in a command prompt box.

Sprint said to send it back to Asurion.
Asurion sent replacement.
Exact same issue.
Epic will hand shake with the router and establish a connection, but it wont give me any data.
Sprint says there's been a nationwide outage for the Airrave 2 which explains why that isn't connecting.
2 phones, exact same issue??? Something smells fishy.
All devices connected to the router work fine except the Epic.
How can I trouble shoot this?

Did you run IPconfig and get the necessary data to manually enter in your phone? Is there some security settings in your router preventing you from getting on the net such as guest settings? Do you have the correct security type set such as WEP or WPA? Is the password correct. Have you powered down your router and modem before trying to connect with the phone?
I was only able to connect by powering down the modem and router, then after it came back up my phone would connect but not after a few days so I manually entered the settings in my phone and never have a problem. DNS server settings are important. You should be able to use most IP settings from 192.168.100.1XX.
If all else fails try contacting the customer servce for your router.

I guess while we are on the wifi connection stuff.. i got a question..
Ok here is my dilema almost everyday when i get off work my router will not connect to my epic it registers it and just hangs on obtaining ip address and just hangs forever.
However if i reboot the modem and router it connects instantly and works fine..
ive tried starting from scratch on setting up my router and still is an issue.
this issue also occurs using my wifi on my xbox as well as my ipod touch?
but for some reason it connects to my computers just fine??
Any thoughts, one thing i saw for a suggestion was update the router firmware which i havent had a chance to do yet..
anything i can do to fix this so i dont have to unplug and plug back in my modem and router almost everyday?
thanks

Did I run IPconfig? No, I'm a mac guy. But I did see the ip addresss inside my router, under the mac address filtering and a quick look at connected devices. I put that in as its static ip. I also consulted my router for all the other information except netmask. I've tried it with the subnet mask listed in the router and the phone scans, connects and super quickly I see something about an ip address, then it disconnects. So I just leave out the netmask and I'm able to connect, but still no data.
As I said, I'm able to handshake with the router. I connect by manually going to the ssid which is not being broadcast. I enter the correct password and establish a connection. But the browser on the phone says unable to display page.
The DNS are directly from Comcast and work in my router.
I spent about two hours yesterday talking with Linksys and they trouble shot everything and told me the problem was with the phone. They said I have multiple devices connected to the router and everything works fine. The problem is in the phone.

I just updated my firmware on my router, it was like 4 or 5 firmwares old lol

[SOLVED] No Data on Wifi

Hey guys,
I am having the weirdest issue with my wife's phone. A few weeks ago she started complaining about her data speeds at home. Through some troubleshooting, I noticed that while she was connected to Wifi, she wouldn't get data for a couple minutes, and then she would get it for about 30 seconds before it dropped again, rinse, repeat. Now, it doesn't drop the signal, it still says its connected to my network, but will not load any data whatsoever. Turn off wifi and surf on 3G and its perfect, weird.
She was running stock rooted TW on 4.1.1 with LI3 modem when she started complaining about it out of the blue. I figured she had maybe messed something up so I wiped and flashed CM10.1 along with LJ3 modem. Still the same issue. Now I just tried flashing MA6 and its still doing it.
I'm having her just stick to 3G until I can figure out the issue but I'm stumped and am not finding any fixes online. Anybody else had this issue or know anything I could try before taking it in to the Sprint store?

Re: No Data on Wifi
Reset the router in your house. Complete reset then set the phone up again to the wifi it should do the trick.

I will give that a shot tonight, but I think I have done that within the last week because I was having an unrelated internet issue. I was under the false impression that the modem affects wifi, but that is the kernel, correct? But that changed when I flashed CM10.1 anyway and still no beans. Hopefully a good router reset fixes it.

Unfortunately the router reset didn't work. I'm at a loss but I *really* don't want to take it in to our local Sprint store because they are a bunch of idiots.

Did you update profile and prl lately? Sometimes mine misses the update and then everything is fine when I do it manually.

Just tried, still no beans. Weirdest thing ever. Wifi works for 30 seconds then I get nothing but network connection error everywhere for about 2 minutes, then data comes back. I wonder if its a hardware issue. I just flashed back to stock rooted MA6 + kernel and its still acting up.

Search on google, the programming codes are usually not specific to a phone so its safe to try and use one that you see somewhere
And even if it is specific to a certain phone, then it just wont work when you dial it, no problems come about as a result of trying them

Wifi not working properly

This is strange, my wifi works but then suddenly it only uploads (only green arrow lights up) and it will not download (orange arrow will not light up). I can disconnect and reconnect and I get some service, but then nothing happens.
I've tried the following:
Rebooting the phone several times
Restarting the router
Changing from DHCP to Static IP
Turning off the new open network notification
Clearing data from Google Play store
Disabled wifi power save with *#0011#
Nothing seems to fix it. What is going on?

READ BEFORE YOU FOLLOW ANY OF MY INSTRUCTIONS!! U HAVE BEEN WARNED I AM NOT RESPONSIBLE IF YOU SOMEHOW DAMAGE YOUR PHONE!!!
OK so let's go straight to Ur answer.... Let it sit for a while after it boots up (a minute) with Ur wifi on. so restart the phone while wifi is on and let it sit for a while... If Ur using a wired connection with a wireless router disconnect the wired modem then the wireless and wait 10 secs and reconnect the wired first and let's all the lights go green or whatever color they show u its ready and then connect the wireless router and try to connect to it.
If that didn't work and you don't have your phone rooted then flash the only time that we have for now. That should fix the wifi issue.
If it doesn't work try to go back to stock and let it sit for a while without touching it and if it doesn't work then the phones defective but keep in mind that if you went through the root process that if you send it back without erasing the flash counter your warranty will be voided so be aware of it. I don't know if there's an app compatible with the s4 so if it's not rooted then replace it just to be safe.... It's your choice
Sent from a phone better than yours!

My phone is not rooted.
What did you mean by flashing the time?
How do I erase the flash count if I decide to root later?
Thank you for your help. =)
------edit------
The method -- sans the flashing the time -- seemed to work, but then the internet stalled again. This is happening on two S4 phones. My other phones have no trouble with the wifi, my pcs have no trouble with the wifi. What are the odds that two phones aren't working? Nobody else is having this problem?

I have already made a thread with the sane issue. You're not the only one facing it. A lot more people are too. It might be a software thing and might be fixed in the next update. If not, exchange it

What router are you using? D-Link DIR-655 seems to be most popular one people are having trouble with. What mode are you using (a/b/g/n/mixed/etc)? Mine only works with Mixed n and g mode. When you turn off the wifi, does it actually turn off (the green indicator will dim but should actually go away when it's off)? The stock rom seems to want to keep the wifi on at all costs... not sure why! Mine is very stubborn and takes several tries before it actually turns off and says "turn wifi on the see available networks." In order for the *#0011# Power Save Mode Off setting to work, the WiFi needs to actually turn off then back on. I have to toggle airplane mode sometimes just to get the wifi to turn off.

DGL-4500 is a D-Link, correct? If it is a D-Link, I'd make sure you are on the latest firmware for it and try various mode settings (disable mixed modes, 2.4GHz or 5GHz only, WPA2/TKIP only, etc). This post details a solution to my scenario; maybe it'll give you some ideas.

Yes, it's definitely a problem with the phone. I've spent the last several days researching and trying to find a permanent solution. It appears to be a software issue but I've yet to explain how wifi works just fine for some and not for others.

Any solution to this yet without messing with the router setting. I have this week left to get a full refund. I doubt exchanging it would make a difference. Plus tmobile is out of stock and stores won't allow exchanges since I bought mine online.

[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
