Wifi not connecting

I have upgraded the phone to gingerbread and have problems connecting to wifi in school. I can see that it is secured with WPA/WPA2, others have no problems connecting.
I had the same problem with a Hero, it just worked with one ROM (not gingerbread), but those other who can connect have gingerbread.
Wasda problem?!
And it's not rooted. Kinda new phone you know and has warranty.

I have the same issue, my phone will only connect to some routers and other people have no problem getting i wifi connection. I'm using MIUI 1.12.16. Anyone have any idea on how to sort this problem out? Thanks.
I can connect to any routers but if i go to WiFi Settings and see if i am connected, it had a little icon next to the router name. When i am connected and i can get internet on my phone the color of the icon is blue (because of my theme) and if i am connected but i can not get internet the the color of that icon is like grey even if the connection is 100%.

Maybe that's a Kernerl problem? I had the same issue WRXRB320 with my router! I changed wi-fi settings from Wpa2 to Wpa and still not worked.. than changed kernel to vadonka's and installed "set DNS" from market! I don't know if the app can solve your problem but give it a try!
EDIT: The app works only if your device is ROOTED

Hi, i'm on vadonka's ETaNa kernel and my wifi is working now with 1 of the routers in my house, but with the other router when i try to connect to it, it says "obtaining ip address". I will download set DNS from the market and see it that will help me, thank you
I tried the app and my phone was still stuck on "obtaining ip"

Crazy wi-fi issues ("Obtaining IP Address...")

OK, I know some people are gonna think I'm absolutely nuts (and who knows, maybe I am ), but my wi-fi was working just fine last night. No issues, connection problems, no nothing. Then I went to bed.
When I woke up this morning, I turned on my Note but began having major wi-fi issues. Whenever I try to connect via wi-fi, I keep getting the message "Obtaining IP address...", yet my Note never obtains one. I've been fiddling around all day so I can get on the Net, but to no avail.
Does anyone have any idea what's going on here? I'm running stock ROM and made zero changes to my Note & router. Everything is exactly the same prior to when I went to bed last night.
Has anything similar happened to anyone else??
Thanks in advance, guys.

even i faced the same issue whole of yesterday...i thought it was some problem with the rom and changed back to the stock rom..but of no use...but today morning its working fine...seems wierd
its again stuck up in loop....connected..obtaing ip address..connecting

Ive seen this happen with a few different samsung phones and usally resetting the router will fix the problem dont know y

i have the same problem
wifi suxks

I had this issue, it would reboot TWlauncher, then work again.

Happens all the time. Use static IP as a temporary fix, it won't lose IP addresss again.

I have the same issue's, it seems to be an Android issue my previous Gnex had the same and i thought the wifi chip was broken or something.
After using the Note for 2 weeks on a random day i didnt have wifi and it had the same symptoms it could not find an ip adress. Now i simply use 3g at home.
I think it has something to do with either the wifi password encryption (wep, wpa, wpa2 etc) i have wep. Or the ip adress that is dynamic and not static.
Whats your wifi encryption?

Tried this already. I can connect, but now the wi-fi connection gets dropped for some unexplained reason every 5-10 mins or so, and I continually have to reconnect, which is extremely annoying. And that's not the only thing. Whenever I'm connected and using data, my laptop somehow loses its connection. And I know that my Note is the culprit because as soon as I disconnect it, my laptop immediately reconnects. Weird.
What makes this so frustrating is that I can't pinpoint the source of the problem. Literally everything on my phone and my laptop are exactly the same as before. I could understand if I was running a new ROM or installed a bunch of new apps/software on my devices, but that just isn't the case here.
I also tried resetting my router, but that's just a temporary fix (at least in my case). I've already had to reset it 3 times in the past 24 hours, and I don't look forward to the prospect of having to do this on a regular basis. Heck, I shouldn't have to!
Anyone know why Android (or the Note) does this? I still love my Note, but this wi-fi issue is fast becoming a nuisance.

Maybe your laptop and the Gnote are trying to obtain the same static IP from the router? (Check to see you ain't asking for the same IP!).
What does the router think is connected when you have both Gnote and laptop on?
Also, if that fails try the following.
1. Change Wifi channel
2. Remove the wpa+wpa2 option and just stick with wpa or wpa2 only.
3. Use a different subnet e.g 192.168.0.x to 192.168.1.x
4. Check the DHCP lease time is short enough (say 10 hrs).
5. Check you are allowing enough connections to be given DHCP IP's
Let me know how it works out.

I tried resetting my router but did not help, since my first post in this thread i flashed imilka's aosp v07 rom and now i'm back on wifi very weird.
My previous rom whas the chinese ics repack (no wifi at home) and the one before whas stock LA6 after a week use the wifi dropped out on that rom.
I still have a less secure wep encryption, but happy for now with the imilka rom.

a simple solution is to add your phones mac address to router whitelist. ..

I have same issue here. Whenever i turn-on my wifi, it scans public wifi even-though i have my own wifi with me. When im in public places and there's this public wifi, i cant connect. rather searching for another public wifi or and error message occur obtaining IP address.
my temporary solution is to disconnect from the connected address and reconnect the device again. Basically it helps

I swear, this wi-fi business is driving me nuts. Presently I can connect using a static IP, but even though I do connect and the icon shows a strong signal, I now have a new problem...I can't use the freakin internet!! I keep getting the message that I have 'No connection'.

Any solution to this? I have similar issue on my Note2 and Wifi works only on Stock Rom.

try changing the wifi setting in router to transmit only b/g and check

Not a router issue...
This is not a router issue, it is due to the wifi modem in you phone being messed up, have you tried flashing a mmodem fix for your phone? alternatively it could be due to file permissions.

First, you resurected a year old thread.
Second, you claim flashing a modem.img or baseband will fix wifi. Baseband AS NOTHING to do with wifi, the wifi firmware is (unless i'm mistaken) in /system/etc/wifi.
The problems op describes are hardware fault...

True.. Its drivers are in the kernel. Thus modem has nothing to do with it.

Wifi - Obtaining IP address

I have been having this strange wifi problem lately.. I am not able to connect to my home wifi network.
It says obtaining IP address but never connects.. This problem only occurred recently.. I was able use my home wifi before.
After googling around, i tried the following.
1. I went to advanced setting and used static IP. This time it got connected. But i was not able to connect to internet.
2. Did a factory reset.. Then flashed stock using ODIN. Still no luck.
3. I changed the encryption to WPA-PSK... Didnt work.
Can somebody help with this issue please?

Hmm..did u flash any kernel?

I had this problem when I tried to update busybox. But since you have re-flashed stock.
Are you sure its a problem on your phone and not with the router? Try connecting to a different router.

Remove the WiFi connection from your phone, click on forget.
On your router,from the configuration page, change the WiFi security to open then try connecting using phone.
If it works then remove connection from phone again (click forget), and configure your router to WPA or any other such algorithm. Then connect again.

My brother has this problem, have you tried other wifi networks? It may be able to connect to other routers. What does it say after "obtaining ip address", does it connect or do you get disconnected?

HTC one mini 2 wifi problem

Hi i am having a strange problem with my phone connecting to my WiFi at home on my phone. I find it will not stay connected to my router. I put the WPA2 code in and my phone says connected then it forgets the network and asks me for the code again. My phone connects to WiFi at work so i thought it was my router but my computer and Xbox work fine still on-line. It just seem to be a problem between my phone and router. I have tried lots of things from hard resetting my phone to changing the security on my router and resetting it I am now at the point where i am at a loss and have no idea how to resolve my problem. I have updated the software on my phone but still no joy Does anyone out there have the same problem or able to advise
Thanks

Hi,
I can't find anything relevant for you, so I will have your thread moved to your device section. ?

I'm not sure but I read somewhere this is a bug in the htc software. You can fix it by having a wpa code shorter the 6 characters I believe. Or maybe try changing to other wifi security protocol

If your phone connects at work with no problems, than its not the phone. The problem will be between the connection to your router. If changing protocol dint work, you can try open network (No pass, just for testing) if connects then its the security.
You can also check in wi-fi advance settings "wi-fi frequency band" its set to auto.

after updating to android 6 wifi connects and disconnects intermittenly

As the title says, after update i am not able to use wifi. Connects and disconnects periodically. I thought that data connection may on so switched off mobile data off, but still same. I had factory reset also, no use. Can anybody give me any insight as to how to solve this problem?

No one know the solution to fix this issue?

I got the solution. change the wifi security settings in your router. change it from wep to wpa personal. Now my wifi is not disconnecting. O course you will need to change the password.and restart both your router and phone after changing I got the solution from lenovo forum
