My brother was able to help me connect to our home wifi through a static IP. However, despite my GT's being connected to a WiFi (strong connection at that), I cannot browse/surf the internet! It always says, "No connection"! Has this happened to any of you? How did you solve it? Help please!
I had this problem and the whole dueling IP address makes sense... not sure why this would happen... the Galaxy Tab can "see" my home WiFi and shows a full signal - it just won't connect. I thought I'd do the static address change but instead I just "rebooted the router"
1) turn off router
2) turn it back on
3) Connected!
I'm not sure if this will help anyone with their current problem, but here goes anyway. I've found that for some reason, not sure why, these android devices (this is not a put down .. just fact) have trouble connecting/reconnecting IF and only IF, your SSID is not being broadcasted. I've seen this almost from day one of my purchasing my EVO and it also happens with my SG Tab. If you have your Router set up to NOT broadcast SSID, then you might want to reverse that and broadcast it and see if that helps in your situation. ALL of my other wifi connective devices do not have a problem with this broadcasting issue, and believe me I have a ton of them connected. Only the Android devices have this problem (it seems like).

Guys i have the same problem on my galaxy tab, i cant connect on wifi at home because i have obtain ip address from wifi and i have the same router tplink, please guys if someone has resolve the poblem send me email on this: ghady_n@hotmail.com thanks all
Hi, when you say "find the location in your particular router that allows you to reserve IP addresses by device" do you mean MAC address filtering? Would I then need to do manually add the MAC address for all of the devices that use this router? Or is there some other way of reserving IP addresses by device? BTW, I have a Belkin router.
Thanks
I don't know if anyone still have this problem. I got my tab 2 weeks ago and ran into the same problem that it suddenly refused to connect to my home router. It could find the ssid but could not obtain an ip address.
I searched on the net and found a work around and would like to share it with who ever is having the same problem. It seems that the tab log the ip address it last connected in the dhcp_list file and refused to accept a new address. So if you are using a router at home with a non-fix ip, it will change the ip every time its reconnect to the modem after a reset or power off or what ever other reasons. Just simply remove that file and it resolve the problem
You would require root access and terminal emulator for this to work however.
1. Install terminal emulator from market.
2. Install Superuser from appbrain to gain root access.
3. start emulator and type the following text in red:
su (to be root)
rm /data/misc/dhcp/dhcp_list (to delete the ip address log in the tab)
I also install Scripter and made a script to save me typing it over and over again since it happen very often to me.
The Allshare App worked for me. I had it happen two times today... (left and came back)... And both times got connected by opening the Allshare after it would not connect... I am using Fios...

PERFECT! Exactly the solution I was looking for, many thanks
i deleted all connections to my linksys wrt54G2 router
then switched off all devices (BB, laptops, etc) connected to the router
then switched off the wrt54G2
told GT to forget this network
next switched on router
et voila the GT was the first to connect and now it is working again !
so yes it must be something with the GT accepting only his first IP adress despite DHCP on the router

good luck all
What do you mean you deleted all connections to the router?
Did you just pull out the cables attached to it?
Sounds easier than doing the Static IP stuff all the time.

Dude you are awesome !!! i got my new Galaxy s i9000 yesterday and it worked fine last night ( my laptop was offline) at home. This morning i started my laptop then tried to connect the Galaxy without luck for 8 hours ... till i read your solution and its now working perfectly fine !!!! many thanks.
The problem is that the galaxy tab 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 galaxy tab will not allow, still wanting the old IP address.
The Fix is to create a static IP address. Go into wifi settings click menu and then advanced. Look up your dns server, gateway and netmask and set the corresponding fields in your galaxy tab settings. Make sure to also see what the IP range that your router can give (mine was 192.168.1.2 to 192.168.1.240)
Also dont forget to click use static IP address. I used 192.168.1.20 because I will never have 18 wifi devices on my network at once.
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
you are awesome !!! worked very well for me. many thanks !
but i have solutions worked for my galaxy tab
my step should be;
1. disable connection to all machines/computers from your routers
2. go to setting-wireless and network-wifi setting and forget your existing wifi (if you have connected your galaxy tab before)
3. using Allshare, connect your wifi again
All share=nope
Static IP=nope
Delete all connections and reboot=nope
Galaxy Tab is a POS
Never even a glitch with my Viewsonic Android Tablet so it is NOT an Android Issue! The Tab has never left my home, this is my second Galaxy Tab as the first one was returned to Sprint. I am so disgusted...
Hi all, after my GT did this today, I googled and found numerous replies, all saying similar things as on here, but i did not accept that i need to set up a static ip for when home then dhcp when out.
after a few moments thinking about this, I decided that if its the GT trying to use the same dhcp IP its got in "memory", and conflicting with another device on the WLAN.. then I'll just change the range for dhcp in the router
Most routers start dhcp at x.x.x.100 ...
So I changed that to start at x.x.x.120
and amazing .. my GT connected to the WLAN 1st try
If you dont know how to change this then i suggest get a Geek (LOL) to come by .. or ring your IT/ISP support
I know this is prob a "bug" in the GT until they upgrade to gingerbread (oh i hope they fix this in GB...LOL) and if it does it again i'll be changing the dhcp begin addy again (and again .. and again) .. lol
I have exactely the same problem with my galaxy tab 10v1.
It connected once to my belkin router, but since then it doesn't connect anymore.
I tried the static IP address, but without success.
Desperately seeking for a solution, I wanted to follow the advice in one of the hints mentioned here to "re-root" my device and then deleting the IP list configuration file. But since I got no internet connection, I tried to do it from a PC connection, with "Kies". But here again I did not succeed in installing the reroute software on my device, maybe the software versions of "kies" and the re-roote software is not compatible with the samsung 10v1.
Any suggestions would be well appreciated.

I think I solved the problem by switching the "Wireless Mode" of my router to
Wireless Mode: 54G LRS (instead of 54G auto).
(for most Belkin routers, in your browser type http://192.168.2.1/, go to Wireless Menu, submenu Channel and SID)
For the moment it seems to work fine, keeping fingers crossed.
I had wireless connection issues after the Gingerbread update last Friday. I did a factory restore and all is well. This thing flies when it's connection is good.
i am new on this and doesn't know how to execute the things u said. can u give me a step-by-step instruction on how to do this? i believe this is the best solution on the said problem. thanks for your quick response.
i appreciate ur post ,i cant figure out if i need to find "rm" in super manager or if i need to type it in terminal ?
Our cable provider (Cox) tells me (as does our software engineer son) that this is usually caused by a security feature: the cable modem is constantly changing its IP address, and not all low end wireless routers are equipped to deal with this. They recommend simply (HAH!) resetting the router by either powering it down or by going to its address and resetting it. I talked to a Belkin tech rep who said the same thing. Pain in the a_ _, but it's far better than factory reset of SGT. Don't know if this will work for all, but we have to do it at least once a week, & it does work . . . I keep the solution & address as a link in Evernote so its easier to do, & accessible from all 3 phones.
After reading through all these messages and having the same problem myself, I contacted my cable provider (Charter) and found out the password I was using was from an old router which was replaced a month ago by Charter. The rep told me what the new password should be and sure enough IT WORKS!
Suggest you all check with your internet provider to insure you are using the correct password.
I think i solved the mystery. At least for my set up (using a linksys WAG320N).
I tried all the proposals listed here (static ip, application etc etc), and in some cases it worked fine, but was disconnecting some times; was not steady.
In parallel, i was a bit annoyed from the fact that had to have a static ip configuration, and change it when going elsewhere etc etc; was a pain in general. So I tried several different configurations, and finally got it.
The problem is the N standard of WiFi. Our litte toy Galaxy Tab is not cooperating correctly with it. So I did the following:
Step 1: downgraded my set up in my router to G standard. (In my router you can choose if you want it to work on all standards b/g/n etc, but you can also choose a specific one. So i chose something in random, making sure that it should nevel play on the N standard which is the objective. I chose G.
...
I just got a new Galaxy Tab 10.1 and the above (switching my router to 802.11g from 802.11b/g/n) made it work. I got a Thompson router (standard Telecom router in NZ)

Reason: only quoted relevant section
i have a TP-Link router.... i've tried it several times but nothing happens... hope this problem could and soon... thanks for the inputs sir...
Take care. TP-Link router has some kind of problems with MAC address changer and filter. It can not handle MAC address changes. I bought one and it could not handle these issues. These are true specially in cases where an internet connection is MAC bounded. AH
A was surprise that last night my Galaxy Tab doesn't connect to wifi... while my Galaxy S is connected... I didn't remove anything from my Tab but all it appears is "Obtaining IP address but it doesn't connect...
need your help... thanks...
Rebooting your router should fix the problem. If not, reboot the tab as well. I sometimes have this problem as well. I believe the tab or the router has trouble with the ip addresses.
I am having the opposite problem as you all... I connect to all of my home routers just fine, but cannot connect to open wifi networks away from home. Strangely, I am having the same problem with my Droid Incredible too, as well as my VZW Galaxy Tab 7.
I challenge anyone to top this! I have two Galaxy tabs which both ceased to operate WIFI at APPROXIMATELY the SAME TIME after two months with no problems until increasingly recently finally to enter the now famous ip loop. So it must be the Galaxy! I have reset, rebooted, rooted static ip'd, deleted dchp_list and reinstated it not all at the same time and not on both - so it must be the modem /router!, nope I just got a new router! nope so not that so I now have a new router, two galaxies in different states left overnight in frustration got up this morning turned them on and they both logged in so its not the galaxies, its not the router so it must be Android....... but I now have a Motorolla xoom no problemo so it must be the Galaxy or is it .
For crying out loud someone somewhere must know what is going on aaaaaaargh
[QUOTE=rodfreitas;2205404]Hi everyone! I know the fix for this! I’m Brazilian, so i can't write right!
I had the same problem. My Samsung Galaxy Tab - (GT) P1000L - connected to WI-FI first and after that never connect.
What happen is that the GT first take an ip number (example: 192.168.1.102)
Than we turn off the router and turn on again and GT try to take the same ip address.
And you have a notebook and other things that connect to the router too. And they sometimes take the same ip that the GT is trying to take.
I have a TP-Link router WR642G. This can work with another TP-Link or other routers.
Enter in your browser (in a notebook that is connected to the router) 192.168.1.1 (sometimes is another number. the number is usually under the router, and the Username and Password too) if the password does not work, reset the router (push a clip on the hole) try again.
Turn off other things that are connected to the router.
Now we have to know which ip your GT took first.
Go to you GT and write down the MAC: example: 40:1F:E0:4R:Q3:7A (go to Wi-Fi configurations than click on Menu – Advanced)
(Menu is the first button below in the black border)
Now return to the router (browser in your PC)
Go to the DHCP Settings. Look the Start IP Address (mine is 192.168.1.100)
Go to DHCP – Address Reservation. – Add New.. In MAC Address input the number you see in GT, but input with this (-) example: 40-1F-E0-4R-Q3-7A
Now in “Reserves IP Address” input the IP you saw in DHCP Settings.
Try to connect your GT.
If don’t work, input the next IP, example (192.168.1.101) until it CONNECT!
I hope you enjoy!

I used the basis of Rodrigo's solution but skipped elimination process he used and went straight to the router setup (I have a Netgear WNR 3510 gateway router) as he described for the solution. I went to wireless setup, went to DHCP and Address Reservation, and added a New address. I have the Wifi Analyzer App which gave me the MAC address necessary to input along with the IP address that the GT setup gave me. The key piece was to be sure to refresh the router, which had the added bonus of fixing my wireless printer which I couldn't get to work before either! Thanks Rodrigo for the inspiration.
Now I am getting a consistent wifi signal from my comcast wifi. FYI, I have not had any problems getting a signal with my Verizon mifi card

Hello guys..... for few days i also facing same problem & i just found the solution for that.......go to application/setting/wifi net/wifi.....your tab will scan back the available wifi net.....instead of it connect automatically...you just tab for few second on your wifi net that you chosen.....then it will appear the box....you just re enter your wifi password & tab connect....
