WPA2 issue

I read a lot of threads around wifi issues and all seems to round up on dhcp settings.
What I see is that dhcp settings are not involved in the problem but I see that if I try to connect to a WPA2 protected network I have problems.
If I change the network settings to WEP or free, the tablet get authenticated in a second!
Does anyone else encountered the same problem?

I've got four WPA2 networks defined and the Tab connects to all four w/o any issue. What sort of difficulty are you seeing?

Not with all WPA2 network I can't get the tab connected.
In my home dlink wireless I have problems. Sometimes tab gets connected in one second but for the major number of attempts I have tab trying to connects without success... all what I see is "connecting". I think it's not a dhcp issue because I don't see "obtaining IP address" in those cases so I think it's in loop on authentication stage.
Also, I tried to change encryption method to WEP on dlink network and the tablet gets connected every time in one second, not more...

[DROID3] Connec to wifi but no pages load etc (no connection) HELP!!!

I can connect to my home wifi fine, good signal and everything, but the thing is when I go to say, load a webpage, it just won't load. No matter how long you leave it.
But when I connect to a mobile hotspot Wifi from my other phone it works fine.
Could it be something to do with my router?
Thanks to anyone that try to help

What router is it?
Sent from my XT862 using XDA

If you have a terminal emulator on your phone, you can try to "ping" the router (most likely 192.168.something.1..)
"ping 192.168.1.1" or whatever address the router has...
This is the same address that you'd type in a browser on your PC to configure access the router's config..
And try to ping something on the Internet such as one of Google's DNS server (ping 8.8.8.8)
A few more details might help us help you:
Router brand and model?
Encryption type used (None, WEP, WPA, WPA2..)? ..WPA2 is sometimes downright broken on some router models..
Does your wireless Internet router work for another wireless device?
Does your Internet work from a wired computer on the same router?

Is the router configured for wireless g,n, or mixed? You might need to play with the router configs.

It's a NETGEAR Wireless N Router - WNR2000.
Security: WPA-PSK [TKIP] + WPA2-PSK [AES]
Channel: Auto
All my other devices that I have used the wifi with have worked fine.
This is really annoying, I just can't think of what the problem is..

How many devices are connected to the router at any given time? Try disconnecting another device from wifi and see if that works.

Yeah when I disconnected my laptop and then connected my DROID3 it worked fine.
What is the solution to allow it for the DROID3 to work?

Your router only allows for a certain amount of connections. You will either have to turn wifi off of one of the devices or get another router.... simple solution would be to turn off wifi one of the devices when you are not using it.

Try changing the security to WPA2 with AES only - I've seen problems with Android phones in the past when both TKIP with WPA and AES with WPA2 are enabled. If you have any old devices that don't use WPA2 (unlikely), then try WPA with TKIP only. See if that fixes it.
If not, and it's a device limit issue, check the DHCP settings on the router to see what the address range is. If it is set to something like 192.168.0.2 to 192.168.0.xx (whatever number xx is), try extending the range to something larger (though no larger than 254, obviously) and see if that helps.

I tried it a second time and a only got connections every minute or something and it wouldn't last for very long :\
It's not a device limit issue because I have had 2+ devices connected to the wireless before.

I second switching to AES. It is more secure anyway.

^ tried that aswell and it didn't work

Maybe try setting a static IP?

Turn off all security on the router and try again as a test.also you might need to reset your wifi connections on your phone. Try wifi fixer

Have you tried resetting the router? Power it down and then re apply the power. I know that it makes no sense that this should work, but it has fixed the problem twice on my D3.

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.

[Q] Wifi Issues

I'm not able to connect to wifi at all with my One, even when I have excellent wifi strength. I thought I had a defective unit but I got another one and it still doesn't connect. I have no trouble connecting at all with my iPhone 4s, Nexus 7, or Samsung Galaxy S1. (When I run speed test with these I get about 7-10 Mbps download and about 10-15 Mbps upload) Is there anything I can do to fix this? (like an update or something) This is my last resort before I bring it back and use my old phone.

Have you changed your WiFi password recently?

Ok I fixed it. To anyone having problems with wifi, on your wifi settings click "show advanced options," change ip settings to static, and change the DNS 2 to 8.8.4.4

If I am not mistaken that 8.8.4.4 is a google DNS. Meaning you bypassed your providers DNS and are now using this one. This would indicate that there is a DNS conflict between you and your provider....and you basically went around the problem. Hey if it works it is all good I guess and of course I may be way of course in the response. If so then please feel free to refer to me as a dum dum
Edit: Let me re-phrase this a bit because it does not actually indicate a conflict. Apparently your wifi router is set to this google 8.8.4.4 DNS and not the DNS that your provider is using. Thus any device going through the wifi router must match this DNS setting to connect.
Many people on lets say XBOX do this to maybe help with lag and stuff especially if the google DNS server is closer to them than there Providers DNS server.. It is really no big deal in the grand scheme of things but it is not a universal fix as so stated in your reply. Hope this makes sense.

I'm having issues connecting to the 5mhz WiFi network while the 2.4 works perfectly fine on same router. Same thing at work... Laptops connect fine. Tried both stock and viper Rom and still nothing... It just doesn't even connect to the network... The pass was entered correctly.

No issues on 5GHz with my Linksys E3000's with dd-wrt firmware. Are you on the latest firmware from the manufacturer of your device?

Using ddwrt myself.. it's really weird cause even at work with their fancy routers.. it doesn't work nor at home... Maybe just defective antenna or something ? The 2.4 works fine.

[Q] Wifi Signal Drops When Trying to Connect

Hey guys. So I attend a university that requires you to sign in with a username and password when connecting with the wifi. I have a Nexus 7 (unrooted), and a MacBook Air. My Moto X is rooted but with everything stock. Every time I try to connect to the network at my school, the signal suddenly drops to 1 bar, and it is unable to connect. My Nexus 7 doesn't exhibit this behavior, and my computer connects just fine. Do any of you have an idea of how I could fix this? Could it possibly be that the network is preventing me from connecting because my phone is rooted? Thanks.

BUMP

Check your Phase2 authentication. Long press on your connection and hit Modify Network. You may have to configure 2 security settings.

What the hell. I changed the Phase2 and then the network signal bumped up but it still wouldn't connect, so I put it back on the default of "none" and now the signal is full and connected. Thanks a lot man. This is awesome.
