Ubuntu keeps getting kicked off of my home wifi. I am very confused about this because it is on a triple boot system, and on Windows 7 I have no problems with wifi (I don't use Backtrack online). But on Ubuntu I get a good connection when I boot into Ubuntu, then after a few minutes I try to go to a web page and it stalls. If I let it keep going it says the server at www.<website I was trying to visit>.com could not be found. Then I lose my wifi connection, and no matter how many times I enter the correct password, Ubuntu takes it, tries to get back on the wifi, and comes back asking for the password. It does this even if I just disconnect from the wifi (asking for wifi password). It is very annoying to have to go to Windows for internet, so is there a fix for this?
