Help Cannot connect on wifi... Galaxy Tab

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.
 
I have the same problem with my galaxy ace phone. Have you solved your issue? I tried all the suggestions in the forum to no avail...
 
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 :)
 
Can I ask please, is this information the same for a Galaxy Apollo phone....received it yesterday and it will not connect to home WiFI. :mad:

Many thanks.
 
Roberttxn pointed me in the right direction !

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.

ok guys I got a fix for this.

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 !
 
ok guys
this prob is really pain in my a**

thanks for the info before me

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

and woootttt.... it works for me
good luck
 
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...
 
I just got one of these last week. I can connect fine and home, but intermittently at work. Should I try "All Share" first?
