[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?

Hi!
I modded CM7.1 on U8500 (based on slax's sp3 rom)...
I imported 2.6.29 icarus chaos kernel into it, everythings fine, except on wifi connect had the "obtaining ip address" issue...(it works with static ip) What can i do now? I try everything...modules, permission...
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 issue

Hey everyone,
I am having an issue where when I try to connect to my wifi, it will connect for a second then disconnect right after. My router says phone is connected.
I have not changed anything recently. I an running cm7 rc1
Any help is appreciated

Maybe try a new kernel. I know when I use some kernels I wont get 4g or GPS or wifi. You can get kernel manager from the market for free. It makes testing new ones really easy.

If its been working before, have you tried to power cycle the wifi router.. I know mine sometimes gets a hiccup and refuses to issue new leases..... just a thought.

True. If the router says its connected but not sending data it sounds like the router not the phone. My crappy router does that a lot. I apologize for jumping to conclusions before thinking lol.

I didn't really think about that. I will try that as soon as I get home and see what happens.

Im on synergy - nightly rom by virus 08/12 and I just recently upgraded my router to be able to handle N wireless, I have been able to connect the other devices in my house successfully expect my phone, my phone sees my router and it prompts me to type in the wpa 2 psk key, I put the key in, it says connecting and then it never connects, would just powe cycling the router fix this or is there something else I should do?

If you have the stock kernel, wifi is disabled by default, though I thought most if the custom roms were hex edited to work.. Perhaps refer to http://forum.xda-developers.com/showthread.php?t=1158629
If that doesn't work try just wpa.and not else, also check if you are using aes or tkip encryption, I remember reading somewhere that it might make a difference which one you pick, but can't remember now... Hope this helps

I just flashed lithid cm's FREEDOM for the synergy-kingdom nightlies v 0.7.6?
Hopefully this works if not i'll try your suggestion of flashing the wireless N fix, the kernel says it supports wireless N so you might be right it might have something to do with the type of encryption the router has for the actual connection, thing is my POS verizon router will not let me switch to regular WPA or WEP for the wireless N connection

[Q] Weird wifi issue

Hi everyone,
I'm enjoying my One X since last Thursday. I did have one problem, though : my wifi wasn't working at home. What happened is that the phone correctly connected at the network, but then it would "kill" the wifi.
I mean, neither of my laptop computer nor my old Desire (which were both connected before the One X) worked on wifi after I connected the One X, which by the way didn't work either.
Considering this issue I wen't to the carphone warehouse to have another phone.
I didn't go home straight, I got to try other wifi network, which worked perfectly.
But, at home, I'm still having the same issue !
Can anyone help me please ?

so none of your hardware is now connecting to your Wifi?
If so, I would suggest a hard reset of your Hub/router. If there is a reset button hold it in for 20-30 seconds, if not, unplug for 30 seconds.
If it's just your One X not connecting try going through settings to ensure its setup correctly.

Had the same issue with my sgs and avm fritzbox 7390. The only thing that helped was a complete factory reset of the fritzbox.

Try using a static ip, make sure it is unique.

There is a setting under wifi advanced to stop the wifi from sleeping when phone is off or kill it if the signal drops or if your phone is idle. I modified those and it works perfectly. Default setting is to kill it.
Nothing is wrong with your wifi. It's just the way you've got it setup.

Actually, my laptop and Desire are connected to the Wifi ; they can't connect only after i set my One X on the Wifi. It's like the phone is destroying the wifi network.

I didn't find those settings. In wifi advanced I only found an setting that disconnect the phone when signal is low.
I should mention that whenever the One X is set on wifi, it works for like a minute. Then all of my devices can't access the internet. Desire and One X are showing that they are connected, but no access to play store, browser... Computer is showing an error message "limited access". And my TV (which I get with my internet box) is freezing.
What I don't understand is that I tried on two friends' network, everything worked perfectly. Only at home As Cxpher said, I guess it must be my wifi that isn't set up correctly. But what can I do next, except hard reset and static ip ?
EDIT : I tried to connect the One X without having any other device connected. It worked, but as soon as I launched the Play Store, I lost the connection and had to reboot my box. Apparently the Play Store is messing everything up. Weither I have hardware connected or not, it never works (again, only at home).

Up.
Anyway, not being able to use my own wifi is a bit annoying

Same exact issue. Phone going back tomorrow.
WiFi fine for 2 years.
New one x WiFi dropping and having to reset router after 2 mins connected as all WiFi dies.
Seriously fcukd off!

Which router do you have? Is there any logging-function available in the router software/firmware?

Standard netgear.
It's been fine with s2 and hasn't needed to be reset for a over a year....until yesterday!.
Not overly tech, would a log facility help?

A log would help to see what is going on with the router when the phone connects. The fritzbox showed an authentication error when my sgs connected and killed the wifi for all devices in the network. Just googled your problem. Netgear and htc devices seem to have problems very often when connecting. You should try to get the newest fw for the netgear. Maybe that solves the problem.

Thanks for your help. Latest firmware is installed tho.
Bizzar issue!
Shame as its a nice phone too

I have a classic french box (called Bbox). For the record that actually is my second phone. I had the same issue with the first one, so I went directly to ask another one.

So has exchange phone resolved the issue?

Sorry I explained it wrong. I meant I already had the problem when I first bought the phone, so I went to get another one. I had the issue on both One X.

Well i have got a netgear router and have no problems at all must be something to do with you router or it setting i would do full reset and see if that helps

hi guys!
i had the same problem with my router ( netgear DGN 1000), i solved by updating the router firmware to latest manually! no more wifi drops now!
i hope this information can help all users with this issue!

In an other thread somebody had advised to deactivate the wifi password in the router. That helped fix the problem at his phone. I will try this too to confirm that. But wifi without password is an absolute NoGo in my opinion.
here the link: http://forum.xda-developers.com/showpost.php?p=24811292&postcount=6

I'm bringing this up again because issue is still here ; removing encryption on the wifi network changes nothing. Other thing now, it didn't only happened at home but also at work.
Warranty is now void, this is my second HOX and I had the same problem on both. Anyone has a magic solution ?

same issue
Im having the same wifi issue using a D-Link DIR-615. Wifi is working perfectly with other device but when my One X connect to wifi, it freeze the wifi network for all devices. I Always need to unplug/plug the AC cord to reboot and refresh the wifi network and after it may works for a couple of mins or maybe 1 hour and after I must reboot the router again.
My router firmware is up to date but there is no more support/firmware update for the DIR-615 REV. B since 2008!
I switched to static ip and snag persist so im back in dhcp.
I cleared the router log and will post it next time it will freeze.

[FIXED] Your phone sees your router, but won't connect? See this!

Gsm Gnex running AOKP M5 + Franco M3. Now, I last connected to Wifi this morning at 8 am. I come home, try to connect, and nothing. Forget network, reconnect, enter password, and nothing. Just says "Saved, Secured with WPA/WPA2".
Tried reflashing the kernel, still nothing, suggestions please?

EDIT: Figured out the fix! This "bug" in mobile devices (not just Android, but read about iOS and BB products as well) come from not being able to connect to a SECURED network. As in, one with WEP, WPA2, etc for security. Now, this doesn't mean you have to unsecure your network forever so you can connect, but rather temporary.
1) Turn off network security, and make the router entry open.
2) Connect to it via your mobile device, make sure data works, then delete connection. Turn off device as well.
3) Resecure your connection with WPA2 (this is what I used and tested, don't know about other security methods), and type in the same password if you want too.
4) Turn on phone, connect to the network MANUALLY (found that if you did it automatically, it didn't work, ATLEAST for me).
5) Enter credentials, and viola! Should be working fine by now.

Thers 2 kind of kernels in francos app.. Try flashing the other one?
Galaxy Nexus AOKP m5 Franco kernel m3

Worked fine running M3 this morning though, now nothing. What could've changed? I didn't even UV. Should I just reflash everything?

problem with wifi

I have problem with my nexus, wifi is connected but I cannot access any internet. Sometimes interet works normal, then suddenly disappears, wifi is connected normal but there isnt internet
I tired wih other android phone, samsung galaxy ace, but same thing
But nokia n8 works normal, this dosnt happening
I do not know of which can be either the router or the phone
I tried to change settings on the phone and the router but nothing
If someone has an idea, I would be grateful to him

I had the same problem on my nexus, while the wifi worked fine on other devices. I flashed several different ROMS, to no avail, and resolved myself to believe that it was a hardware problem. Before flashing back to stock, I reset the Router, just for laughs. Problem solved. Make sure your wifi settings on android are correct, and try resetting your router. It's worth a shot. Which ROM are you on?

i tired several times with reseting router, even change settings, sometimes internet start to work but after 30-40 minuts stops again
i dosnt now what exactly ROM is on phone, becouse i just buy him

Without knowing the ROM, and at the risk of sounding like a tech support douche, maybe you should try a wipe/factory reset.

Hi,
I am new to dealing with the Android OS with my Galaxy Nexus, but I am thinking the same thing. My main concern is backing up and reinstalling all of my information, apps etc. I use Titanium backup pro for my backups but would like to know if my phone will be recognized when I try to reload all of my apps.
Thank you for your reply.

I have WiFi problems at my house. It shows that I am connected but no internet. I know is the router in my case.
I would test your WiFi somewhere else, such as Starbucks or Barnes and Noble.

Hi,
I have connection everywhere - Starbucks, home, Staples, Chapters/Indigo (Barnes and Nobles equivalent in Canada), even borrowing Wifi from unsecured home networks etc. but the disconnect is between the Wifi and getting my Internet to connect. Connection bars are all gray and at home very strong signal showing. This reminds me of connection problems I had with my laptops (running the MS OS of course), but in the Android OS I am a "newbie" and reading forums trying to figure what other people's connection problems are, and how they were solved.
There are no Wifi connection problems using my laptop (now) or my daughter's iPods, my wife's Blackberry Bold at home. My data works find, and I wish there was a roll back feature to the time just prior to the problem occurring last Thursday. My understanding is I have to completely restore my system, and this leads me to more questions about if I can reload all of my apps or if I will have to pay for them again. In the end, it may be faster.
I downloaded - per member recommendation - a Wifi analyzer and it shows that my home Wifi speed is excellent.
Thanks, I am always open to ideas to solve.
Do you know how to find the version of ROM on my Galaxy Nexus? I must look.
Scott
