recently got a Samsung Galaxy tab 10.1 and everything was working well for a month and then I got these sporadic WiFi connection problems. Typically I have good WiFi signal for a while and then it dropped out for no reason. Resetting my router will fix the problem for a while and it came back again. After researching the Internet for causes and solutions, I found the following:
Root cause: apparently the Samsung Tab has a bug in which it got stuck with an IP address and if your router has dynamic DHCP, the IP address will change from time to time but the Samsung keeps remembering the old IP address and refuses to take the new one.
Solutions:
- one of the solutions that was suggested is to root the Tab so that you can delete some file which contains the IP address. Although this sounds like a logical thing to do, I think it's too complicated.
- another solution is to set both your router and Samsung Tab to static IP address but the drawback is that you have to reset to dynamic IP if you go to another WiFi zone such as Starbucks.
- another idea is that the Samsung tab has problem with the N router so it is suggested to go into the router menu to downgrade it to G. This sounds plausible but I didn't try it to know if it works or not.
- Another suggested solution is to run the Kies Air app and it will fix the problem. This is an app that allows you to transfer files between a PC and your Samsung Tab via WiFi and it also does the file backup onto your PC. Since this app has to connect to WiFi in order to work, running this app somehow fix the problem and I have not had any connection problems in the last couple of days. Hopefully it will stay this way for good.
Just want to share what I have found so far.
