I have had my Tab for 2 weeks now.
At home I had no problem to connect to my WiFi network for 1 week: then suddenly the Tab would not connect and would remain stuck on “getting IP address…”.
I changed from WPA to WEP to WPA2 PSK with no luck
But if I go to a static IP, then I have no problem to connect.
On my office “public” WiFi network, exactly the same problem: it worked for a week and then bingo stuck on “getting IP address…”. Again going to static IP solved the connection problem.
My question is: how do you delete a network from the list? It seems to me that the Tab keeps an IP address in memory and if ever that address is taken by another device, it gets stuck!
Any advice would be appreciated.
I had this exact same issue on the same day I bought my Sprint Galaxy Tab (11/14). I did a hard reset that afternoon, and I haven't experienced the issue since. I'd already had all of my apps downloaded, and settings tweaked, so hard resetting was kind of annoying. I hope this doesn't come up again.
Yep sounds familiar, my Thomson Speedtouch 780i runs on a old firmware which gives me same issue with the Tab, had to run with no security. If you decide to run with no security turn off broadcasting..or update firmware/router..
My router is quite recent and has the latest firmware.
All my toys (iPad, Dell Streak, HD2 together with 3 PCs) connect without any problem.
The Tab had no problem either for a week.
Then for unknown reason no way to connect unless using a static IP.
And as I have not found a way to delete the network in memory (short of doing a hard reset)I am stuck.
And now same problem arises with office netxork:-(
Yeah just do a factory reset in privacy settings i think

My Tab is doing the same thing now. I can't do a hard reset....is there another solution?
Ugh, I have the same issue! Had it for 2 days and all of the sudden it's stuck on Getting IP address from... Resetting to factory defaults was depressing. I wish there was another way!
It also happened to me when I was on vacation at my relatives home. The tab would work for a day or two and then be stuck at that message. I had no issues with doing a factory reset as it was still new. But then I started using the static IP trick and that worked. Now I'm back at home and I don't have this issue at all. Been using it for a week with my wifi and all is well.
Nothing was actually working: restarting the router, forgetting the network, creating the network manually, changing the authentication method, etc.
I'm sure its was an issue with the router at my relatives home, but still why was my Nexus one and Laptop connecting with no problem???
For those who are having the problem, use a static IP for the time being, you don't have to reset.

I ended up switching to Channel 1 on the router at home, and haven't had any problems since. Chose Channel 1 after running WiFi Analyzer.
having this same problem. I've messed with WEP vis WPA and tried static IP. Using a verizon fios router. any help?
Bah, it happened again! Now I really dont want to reset
Same issue here ...
I can get WIFI at Starbucks but not at home ( Open-WRT on linksys )
I wonder if it depends on SIM card being inserted?
Mine is a Verizon FioS router as well, at work. Can get on fine at home or anywhere else. My iPad had a problem here forgetting the network but I could at least reconnect. This is doing exactly like you guys.
I wouldn't even care that much except when I'm inside the office I can only pull in Edge data. Ugh.
I had to change wireless settings on my Linksys - most changes were to disable some fanny things like "afterburner" - and setup wap2 for security to have a stable wifi.
I've had the same problem with my TMobile Galaxy Tab. All I do is to turn off Wifi in the Settings app, then turn it on again. I am usually able to snarf an IP address straight away after that.
It also helps to just turn the device on and then off again. it boots so fast that it isn't too annoying.
I had similar problem at home. My DHCP server had wrong time set. After setting the time on DHCP server correctly everything is back to normal.
i hav a tab on tmobile love it not sure if i had the same issuse as u guys tho the issuse i had was it would work without any problems im talkin about wifi then the next day the wifi doesnt want to lock onto the wifi it would search then drop to start serchin again , now wat i learned is sum apps require wifi to work because high data at the same time it changes sumthing in ur wifi settings after using the app the first time which would require u to master reset the device to resolve the issue the program that was doin it for me was frostwire
same here
my version of the same problem appeared when i changed the static IP of my home router (AVM Fritz!Box 7170). before that i always got a dynamic IP through DHCP on my galaxy tab.
After changing the router IP i only could connect with a static IP.
if i use a different WIFI network instead, DHCP is working as expected.
in my opinion the problem is with the firmware storing the network settings and with no possibility of deleting it completely. a hard reset cannot be the solution...
does anybody of you know if this problem occurs on other froyo-based devices also? is there a way of deleting network settings in a working way?
Had the same problem, EU TAB white Stock 2.2 rooted spot connecting to my main Wifi but connects to 3 or 4 other dhcp APs.
Have a htc Desire whit stock 2.2 + rooted and never had that problem.
In the end i hardreset Tab and no problems 1week and counting.
EDIT
FUuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
Happen again... im not going to hardreset again, im looking for a more permanent solution
Had the same problem. I have the Verizon FIOS router. The solution is actually easy. Just drain the battery of the Tab. Charge it to full and turn the Tab on. I think the Tab really "forgets" the old network after this kind of restart. No need to reset your Tab to the factory settings.
I just bought my Samsung galaxy S i9000 and the only problem i have is with the WI-fi,it works fine until i reset the router(just power on and off), then it starts doing obtaining "IP adress from..." and it wont connect ever again .The only option in this case is to reset the phone to factory setting and this is frustrating.
I noticed that if i turn off the wi-fi on the phone first and after that reset the router and then turn on again the wi-fi on the phone works.The problem is sometimes i forget turning it off from the phone or if a power cut happens it will do the same thing until reseted to the factory settings again and of course i lose all the applications.
Any suggestions are welcome.
Thanks in advance.
Try to change the wi-fi name to something smaller.Also if you use password for the wi-fi try to deactivate it to see if it is the same problem.I feel that it has something to do with the decreption used in the router...maybe i m wrong..
I will try the password removal to see if the problem persists.
Nop, it doesn't work either way, i called a neighbor to come by with his nokia N8 and it seems to work fine for him.
By the way my IP changes every time if i power on and off the router i think the problem might come from there since it says "obtaining Ip adress from...", but then again for nokia N8 works just fine, and i even renamed and reseted the router to different settings and still doesn't work so my guess is that the phone has a problem.
Your router changes IP every time you restart it? Can you explain a little...are you being re-issued a dynamic IP from your ISP thats refreshes when you reset your router? Otherwise I would think even after resetting your router it would default to 192.168.1.0 or .0.0.
Either way it sounds like a DHCP problem...where the router is not properly issuing an IP address to the phone, or your phone has cached old settings and isn't being able to pick up an IP after your router changes IP.
Yea Kops the Ip is dynamic and refreshes every time i reset the router

This is probably the case, any way i can clear the cache?
I've had similar-ish problems when running a custom rom so last resort would be re flashing

I would look into seeing if your router is capable of NAT (as most routers are). This would enable a private network in the 192.168.x.x range, and might solve the issue of it not picking up the new IP if the issue is with caching the old one. As far as clearing any cache related to wifi, I'm not exactly sure where that would be found. You could try going into your Settings > Wireless & Network > Wifi settings and forgetting the network. Doing this and letting it re-discover it may help.
May I ask why you are resetting your router? I see no need for it to happen very often. Also, just let me clarify....if you successfully join the wifi, and leave the wifi range...when you return, will it connect again? Does the non-connection only happen after resetting the router?
Have you tried to use static IP for your phone instead?

This might be worth a shot if you could get NAT working, to eliminate the "obtaining IP address" from the DHCP... but if the IP is constantly refreshing and changing, I'm not sure it would do any good.
Hi All,
I have a weird problem with my captivate of not connecting to my home network. Let me start by telling that I have searched the solutions and tried doing everything except full factory reset. I have rebooted the phone, done reset on my router (Wifi was working just fine earlier.. so I think settings was not an issue. But I still did it), I removed the file data/wifi/bcm_supp.conf and let it regenerate it. Captivate displays "Obtaining IP Address" and it just stays there. I also see that IP address is being assigned to captivate in my router
Captivate is rooted stock Froyo
Router security: WEP
form the Wifi list, I found one unsecured network and captivate connects to that router just fine (signals are very week though...). I tried removing the security on my router but it still stuck on "Obtaining IP address".
Can you please please help me?? As I mentioned earlier, It was working just fine and suddenly stopped working two days back.
These all app updates are eating away my limited data of 200M.
Thanks a millian.
What's your router model ?
What channel are you running on ?
Are others routers close to you running on the same channel ?
Have you tried another channel ?
Did you try WPA2 ?
Could be incompatibility with your router. That happened to me before with my old router. It didn't work with some cell phone wifi devices.

Try using the app "FXR." I had the same issue a couple times and this app seemed to fix it. It took a few tries though. I think it might be a router problem. I use the Linksys wrt54g.
You could also try assigning a static IP address to your device on the router side, and then telling your phone to use that address. I've used that in the past to some success.
As a test, have you tried (temporarily) disabling the security on your router to see if it connects?
I have a similar problem since upgrading to the past 3 nightlies. My phone sees and connects to my home network and says it has strong signal, but when I try to access Market or Internet it says there's a network error and I can't get thru. My two computers (one hard wired and one wi-fi) don't seem to have any problem hooking in to the internet, just my SGS1

Does the 'FXR' app set up IP addresses?
The App didn't work for me. I tried that yesterday. I was reading the similar problems on some other site yesterday and I found the following that solved my issue. In case someone like me still struggling with the WiFi problem.
Delete file data/wifi/bcm_supp.conf
Delete file /data/misc/dhcp/dhcp_list
reboot the device and it will create these files again and you will have to enter your WiFi password again in order to connect.
I am really glad that my WiFi is working back again.
FYI, I'd change the WEP to WPA.

Where do you go to change that setting? I've been all thru the wi-fi settings and advanced settings, but didn't see anything that referred to WEP or WPA.
Just realized we're talking now about the router, not the phone, duh!
Yes, I certainly need to bump up the security settings on my router.

I used root explorer, but could not locate the files you mentioned. Directories were there just not files. I'm still exploring the router side. Thanks for the info tho.
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

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.

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.
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?

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?
