[Q] WiFi problem: stuck on "getting IP address"

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:-(

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.

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.

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. 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.

    Fix that worked for two of my devices

    I had the same issue on my Tab and my Bell Vibrant (after upgrading to Froyo). The devices would get stuck in "Obtaining IP Address".

    This is what worked for me:

    To Fix Android going into “Obtaining IP Address” loop:
    rm /data/misc/dhcp/dhcp_list

    It seems to come from the fact that the phone requests its previous IP address to the access point, without any discover message, whereas the lease has expired from the AP point of view...

    The previous leases are stored in /data/misc/dhcp/dhcpcd-eth0.lease and /data/misc/dhcp/dhcp_list. You just have to remove the second file (dhcp_list) to force the phone to start a new dhcp negotiation.

    I found rebooting my router (WNR2000) helped. I have the same issue with my galaxy S. Looking round the web, other people with linksys products have similar issues with ipads/itouch. You don't have a linksys router like me do you?

    Instructions for deleting dhcp_list file: Manual reset dhcp in Galaxy Tab

    Got same problem but I like to believe this is the solution for it. However it is not clear to me how you did it.

    Do you root the tab first before using a root explorer? Seems kinda logical to me :) .

    Ah nevermind. I found out how to delete or rename the file. Here are the instructions for similar noobs like me:

    1. Download from the Market 'root explorer' or a similar program. I used the free 'Super Manager' with included root file explorer. You must enable the root function in Super Manager, otherwise you don't see the folders.
    2. root your Galaxy Tab --> see SuperoneClick and theunlockr.com
    3. Within the file explorer you should go up to root map folder (in short: "rm").
    4. Then follow the instructions of Gadgeteer81. You can either delete the file or rename it:
    To Fix Android going into “Obtaining IP Address” loop:
    rm /data/misc/dhcp/dhcp_list

    It seems to come from the fact that the phone requests its previous IP address to the access point, without any discover message, whereas the lease has expired from the AP point of view...

    The previous leases are stored in /data/misc/dhcp/dhcpcd-eth0.lease and /data/misc/dhcp/dhcp_list. You just have to remove the second file (dhcp_list) to force the phone to start a new dhcp negotiation.

    5. Soft reset your device by turning it off&on.
    6. Turn on you wifi at your device. Hopefully it will connect to your wifi. Well ... at least mine did :rolleyes:

    Before I started the above I also created a static IP address in my wlan router. Hopefully that will prevent future problems.

    But serious, this problem is really lame. It also exists on the galaxy S phone. We should really complain at Samsung for not coming with a friendly solution for us!

    With a rooted SGS, I successfully removed the dhcp_list file thus fixing the problem.
    But as this is a regular occurance, I downloaded the free android app, Scripter (by fazik logic). Since I can't post links yet, just search for Scripter in the market.

    Allowed it root access with SU and saved the single command line script:
    rm /data/misc/dhcp/dhcp_list

    So now all I need to do is run the script whenever it's stuck "Obtaining ip address.."

    HI All,
    Solution is unplug the power of your modem and leave it for a minute and also unplug the router. Now plug the power of the modem back and wait till all the lights turns on and now plug the power of the router and wait for a minute until all the lights are on the router. Restart your GT and now configure your wifi seetings in GT. It happened to me and doing above steps resolve the issue. My router can only hook upto five wireless devices that was the problem no issue with GT. If i helped you please hit the Thanks button.
