I upgraded to Windows 7 from Windows XP a few months ago. I did all the tests to make sure my computer was capable to handle Windows 7 and it was fine. At first my internet was really fast and worked great, and then all of a sudden it started to run slow. I can't stream video clips because it takes forever. I have to pause it and wait about 5minutes to watch something. I don't know if it's my computer or my wireless router. I bought a Linksys wireless router, when I used it with XP, it was great. Does anyone have any suggestions on what I could do to fix this problem?
