[Q] Obtaining IP Address? Unable to connect to WiFi..

Getting very pissed off at this.. been able to connect to my home wifi and others before.. but for some dumb reason i can't get any good connection from my router that sits three feet away from my device.. everytime it just gets to the "obtaining ip address from " then disconects and tries again.. never getting past to connect.. i currently have reset my router to basic settings and left the network open... i'm running in "g" mode.. channel 6... even with the network running open it still does not connect.. i need help bad..
Droid Incredible 2.2 froyo - Skyraider 3 sense rc2
BaseBand v: 2.15.00.07.28
Kernal v: 2.6.32.15-king#2
Router: Linksys - wrt54g v5 - Firmware: Up to date.
ISP: Comcast xFinity
Thanks for any help..

ok so i changed out the kernal.. went back to using the stock skyraider kernal that i had before i changed to king.. now my wifi is completly broke.. phone does not have mac address anymore.. also want to downgrade my radio back one version.. i noticed my whole wifi connecting issue after going to radio 2.15 or the version before it.. i have been googling around and cannot fin the radio i want, 2.07, or 2.05.. but the fact i lost my mac address form reflashing the kernal blows... anyone know a good way to reinput the mac? or a new flash should fix?

MAC addresses are burned into the hardware so I do not think you lost yours. Try running the code below with the phone booted or in recovery and then flashing another kernel. King's kernels come with a lot of extra modules and they may be causing issues when you flash other kernels and they are left behind. This code will clean them up. This is just a thought. It may help you.
NOTICE: this will render your wifi/hotspot completely useless until you flash another kernel. Also be careful you type in the commands verbatim
While Booted:
Code:
adb remount
adb shell
rm -R /system/lib/modules
In Recovery:
Code:
adb shell
mount /system
rm -R /system/lib/modules

had the same problem and i am running the exact same set up. I fixed the problem by reading the xda forum for that rom and he clearly states that you have to uninstall the wireless tether from market and get the lastest versions. the market is not the lastest version. Go to the thread and he has the link posted to the updated wireless tether.

thanks for the feedback guys.. @ihtfp69: i tried reflashing back to the second stock kernal in the kernal list of rom manager.. can't remember the name.. its weird when i goto the advanced options of wifi settings.. it say's "Unknown"..
i'd screen cap it but i am in the process of just restoring the original rom from factory..
@jager420: its really nothing to do with wifi tether is it? i'm trying to access my router to my phone, not wifi tether to the router via repeater...
Thanks again for the help and especially ihtfp for the adb coding..

drocaps.. this is after wiping then doing a nandroid restore of the phone after deboxing and applying root.. the radio never went back.. going to try downgrading the radio.. then try the adb codes as a last shot.. haven't got adb to work correctly in the past.. i keep forgeting to mention that, at first before i lost my MAC, i would get that issue i metion first.. then after i lost the mac, everytime i tried to turn wifi on it would just say "error".. haha..
--
ok so i went back to stock radio and got my MAC address back.. does bluetooth have a MAC address? can't remember.. under blue tooth it says unavailable..
haha nevermind, had to activate it before it showed up.. so my MAC issues are resoved.. now i just need to get it to connect to the damn router so i can get faster speed on my phone when home..
--
ok so from what i could figure.. i went to set the router to broadcast on the 11th channel.. using 2.462GHz.. has no problem connecting.. its running in g-mode also.. i found that when i set the router to defualt channel settings it couldn't pickup an ip.. channels 1-6 proved to be no luck.. thanks again for the help guys..
--
welp. i was connected good for awhile.. using wifi to install apps and stuff after my fresh install of skyraider 3 rc2.. i have wifi sleep at 15 minutes.. i seen wifi went off and back to 3g.. so i tried to reconnect wifi to see if it would work and nope. back to the same issue as before.. stuck at connecting then trying to obtain an ip from router. never gets past the obtain part, just disconects and trys again... looks like i'm back to square one.. could use some help before i go nuts... fixed the system info in op to show whats going on now..

I'm also having the same issue where i cannot connect to my wireless router. Are there any other possible solutions? It's strange because the phone will connect to a neighbors open wireless network but will not connect to mine. It just keeps cycling through and cannot obtain an ip address. Thanks in advance.

what router do you have? make? model?

This thread has been dead for a while, but it's the only one that describes my problem.
I am using the latest Skyraider Athena right now and whichever kernel it comes packaged with.
Until yesterday, I was able to connect to my home wifi network without any problems.
Last night I noticed that it would try to obtain an IP, but fail and try again... over and over again.
I took my phone to work and it connects to my work network fine. It also works on my fiancee's network.
WHAT HAPPENED?
I reset my router and it didn't help. I really need wifi access in my house since I'm in the basement most of the time and I don't get cell signal.
Any ideas? I've thought of renaming my network and changing the password. That's a huge PITA considering the number of devices I would then have to change the settings in.
Please, someone have an answer.

I'm actually having the same exact problem. I'm able to connect to other routers in my building that are open, but for some reason I can not connect to my home router. I'm using a D-Link DL 624 router.
I'm at a loss as to what to do.

also have the same problem here...
device = motorola atrix
when i turn on wifi, it detects my home network and keeps trying to obtain ip address
then it scans agains because it can't connect and tries to obtain the ip again
after trying for a minute or 2, the home ssid becomes:
"disabled, secured with..."
please help

Bump...
This problem is really getting annoying because I can't connect to wifi at home...
Any ideas?

This may seem a little too simple.. but I remember my dad having a similar problem with his EVO. All I had to do is "Forget" the network, reconnect to it, and re-enter the WiFi password. Is it possible you changed the security on your router? Your phone is probably trying to connect with the old password you had before if that's the case.
Good Luck,

Thanks for the reply. Unfortunately, that dindt solve it. It is now connecting to wifi 50% of the time and the other 50% keeps trying to obtain ip

Sounds like an issue with a mismatched Kernal for the ROM your using or just a bug on the ROMs build. Had the same issue with MIUI roms when I first tried flashing kernels. Mine would scan, obtain & connect, and then drop and scan for other connections. What setup are you running?

I am on stock atrix but rooted. Haven't flash anything yet cause I am still learning this rom buisness... could I be having a kernel problem?

Any idea?
Thx for ur help,

Same problem here with all my android devices....
HTC EVO stock (2.2) did the same thing with rooted 2.1 (unrevoked)
HTC EVO 3D stock (2.3.3)
Samsung Galaxy Tab 10.1 stock (3.1)
Happens on my home wireless router as well as work. Sometimes, just sometimes I'll be lucky and it'll connect after multiple tries or reboots of my home router (cant touch the work one).
This has got to be an android issue...right?

guys i wish i could remember what exactly i did to fix it... i haven't had the issue since..
try checking the wifi type? as far as i know, type n is not going to work. i could be wrong.. try b or whatever else floats your boat.. also, it could be the kernal.. i have been using my incredible with cynogen mod 7 and with no problems on the standard kernal.

WiFi connect loop on WPA/WPA2 PSK

FIXED:
Apparently the router had a reset button which I just dicovered hidden between the vent gaps, which has a different function than just pulling out the power cord for a minute or so. Now WiFi is working on my phone.
My phone won't connect to a WPA/WPA2 PSK WiFi network. It previously was able to connect (for 2 weeks), but since 6 weeks, it loops: scanning, connecting, disconnected. I have flashed many ROM versions and wiped all phone memory since (mainly for other purposes than this problem), but it still won't connect.
I have tried resetting the router several times without result. I can't access any more settings, because I live with other students in a house where the house-keeper also lives.
The WiFi at my university (802.1x EAP) and the WiFi at my parents house (also WPA/WPA2 PSK) always works properly.
I have searched through the internet and through XDA-forums, but none of the proposed solutions works, can be done on my phone or I am not able to try them because I can't access the router settings.

How about different kernels?

I have the same problem. After unlocking bootloader/rooting my Arc it doesnt connect with my router anymore. My other "still locked/unrooted" Arc has no problem connecting to the router...
edit: seems my BT is having problems aswell.. couldnt connect/find any other devices

I'm running stock 2.3.4 with stock kernel. DoomKernel still has problems isn't it? I'll have to live with it till that's fixed. Already tried reverse tethering, maybe that will work.
It's not such a big problem, as I have my laptop near me there, but installing apps is quite a hassle this way (search for .apk, install apk with flashtool or move apk to sd and install).
I don't have a data plan, it's €10/month for 200mb, pointless for me, because there's WiFi at home, at my university and in the train.

When you restoring your phone and after that making setup, then dont log into your google account. Install freshly new rom and directly try connect wifi. If i remember right i had to thiskind problem. And after i realized that problem was "google settings and thatkind stuff backup restore". I just uncheck this option and after that i was abel connect my home wifi. Before that i cant. give a try

I am using recently acquired Xperia Pro. I get very weak wifi signals in my room so i bought a Thomson Wifi Repeater/Access point to extend the wifi signal to my room. My phone is now unable to connect to the wifi and keeps scanning, connecting and disconnecting. It eventually ends up with a Limited Connectivity noticfication meaning i am unable to connect to internet although get full wifi signal strength. I tried changing some IP configurations but it hasn't helped. Interestingly my Notebook PC is able to connect and maintain somewhat stable connectivity, although at times it too gets disconnected from the internet. I tried connecting to the Wifi using an iPhone and it too had the same issues i.e able to detect the wifi signal but unable to connect to internet.
I am still trying to find the solution to the problem and will update if i find a way out.

I suggest that you update both your phone software and the router firmware to latest possible version.
Let me know how it goes.

same problem
I have the same problem on my arc s after i downgraded the official ICS to gengerbread using flashtool i even tried to upgrade back the ICS but the problem hasn't been fixed

Fixed
Try to find setting on your router like "max number of peers" or something like that and change the value to maximum it can, maybe it will tell the maximum number. After that reconnect your phone wifi, and bless me:angel:

Had same wifi diconnect loop problem - solved
I had the same WiFi loop - connect/disconnect issue. Extremely disturbing.
It appeared out of nowhere.
Rebooted the phone and the router several times - no help.
Used WiFi analizer to check for interferring chanels - nothing special.
Changed the WiFi chanel anyhow - no help.
Reinstalled/uninstalled AT&T smart WiFi - no help
Removed my WIFi network ('forget' button) and found it again, including the password - no help.
I have the WiFi manager installed, but I sort of forgot to check it doing everything through settings.
Only then I found that my WiFi Manager is stuck on the update announcement screen.
Okayed it - problem solved.
Funny thing, I don't remember updating the WiFi manager lately.
Feel so stupid wasting 2 hours.

[Q] Defy not connecting to wifi network :(

Hi,
After upgrading to CM7 i was not able to connect to my Wi-Fi Network.after going through some threads i found that some people do face the problem so i again upgraded to WajkIUI 1.7.15 But sadly i am still not able to connect to my home network even after removing all security from the network it just shows network remembered and on pressing on connect is just shows scanning ... can any 1 help please.
Thanks In advance

This may sound like a no brainer but if you haven't already, reboot your router and see if it helps. Or perhaps switch to either B, G, or N rather than running your router in mixed mode. Seems like most peoples WiFi problems with cm7 are router related

Just did that but no help i guess i need to downgrade to Stock 2.2

Do you have a Titanium Backup of your system?
If so, reload your wifi configuration. I had problems with wifi too not finding any networks, and restoring it fixed things.
Compass.

even i had same problem but this method fix my problem .... here is the solution ...
The problem is that the defy is getting an IP address from your router and holding on to it. If a new device comes onto the network it will try to reassign you an IP but the defy will not allow, still wanting the old IP address.
The Fix is to create a static IP address. Go into settings .....wireles nd network ...wifi settings.....click menu and then advanced and click use static IP address....now look up your dns server, gateway and netmask and set the corresponding fields in your defy settings.
I hope this helps becuase I was banigng my head over the table for 3 days trying to fix this.
Oh and u have to turn static off when you use your wifi at another location....

"Obtaining IP Adress" no WIFI connect

Ok,now im stumbling around some really strange sort of bug or whatever that is..my Xplay won`t connect to my home WIFI anymore,it happened suddenly,no new apps installed,no messing around with anything,its in a "loop".when i turn wifi on,it scans for network,finds my home wifi as usual and then its stucking at "obtaining ip adress".after a few seconds it turns off WIFI and does this again.every other device here has no problems connecting to my wifi network..tried different settings,turning off mac filtering and so on,nothing seems to help
i was on doomkernel v8 with the wifi modules flashed for 10days or so now,today this happened and i have absolutely no clue how i can get the wifi to work again..i reflashed the wifi modules,same..then i flashed v6 doomkernel with the stock wifi modules..same,won`t connect anymore..does anyone have a tip or solution,i seriously dont want to reflash the whole phone..anything else works..seriously pissed now as i`m sitting here in the third hour trying to get the wifi working again

I had a similar problem but on my tablet s. I tried reinputting password, redoing the connection but could not fix it. But after rebooting the router it worked. Hope it helps

having some wifi issues..

Hey all,
recently i've been having some issues with the wifi on my kindle fire. when i put it to sleep and put it back on, the wifi will show as connected but nothing will load until i switch wifi off and back on again. i have wifi sleep policy set as "never switch off"
also sometimes the wifi will randomly disconnect from the router, although i'm well within range. when this happens, i can't reconnect unless i switch the wifi off and back on again. i'm using cm7 hellfire, any suggestions?

Which rom?
When I am at home (netgear WNR3500v2 with DD-WRT) I have no issues.
When I goto work (AeroHive Enterprise access points) I run into the exact issues you describe.
I ran into this with the stock rom and all roms I install. ICS with Kernel 3.0 has this issue, but it is less common. With everything but a 3.0 kernel, I can use the wireless for seconds before it dies.
Googling the issue I found that it is pretty common for any android system when connecting to a corporate wireless access point.

I'm experiencing same problems with stock and CM7 Barebones 9-2-2012.
Searched a lot, and beside nonsense advices for routers resetting (how can I reset the router at public hot-spot?) given to the users of PORTABLE device that Amazon customer service is pushing trying to hide their own problems, I found only two explanations that are reasonable and reported to improve things:
1. One reported that deleting/forgeting all remembered networks in Kindle's WiFi settings and creating new connection that is used later on makes problem-free connection. Please do not blame me during entering SSID and passwords all the time. Blame Amazon. As far as I remember, when I unpacked my Kindle I had WiFi connection without problem at my home. Problems started when I connected it first time in my office. Intermittent disconnects continued at my home also. Searches show that a lot of people had problem-free period of using Kindle's WiFi. Makes sense, but I will do deleting/forgeting only under gun pinpoint. Or when I decide not to move my Kindle around.
2. Other reported that making Access point to use g-only bandwidth instead of mixed mode improves things. You can do it at your home, maybe in your office and sure not at public hot-spots. I did it at one place, I will do it in another, looks promising on first try. Do not blame me if you have now trouble free Kindle WiFi only at your home, maybe at your office and frustrating internet access in public areas. Blame Amazon.
3. My way. Installed WiFi Fixer and saved frustration to slide up, WiFi off, WiFi on procedure, back. Doing that automatically. Magic. Anyhow, there are moments when it is doing his job, so You get no connection reports from browsers or other apps that need internet connection. You already know about blaming....
Waiting for daily use kernel 3.0 and ICS, I believe that developers here will not let us down. Long live XDA-developers community!
