I tried to go from normal ubuntu 12.04 to edubuntu 12.04 because I had some problems with my wireless connection. The problem still occurs in edubuntu, the wifi symbol says that I got signal but when I go on the internet, suddenly after a random period of time I cant download/browse anymore but the wifi symbol still says that I got a signal.

This problem also occured when I had Windows XP with SP3 installed, I thought It was a case of bad drivers but I never really found the solution.

I´m kind of fed up ATM because for the last few days I´ve been trying all I can to get my computer to work again under a different OS than Windows, so far unsuccesfull.

I hope someone can help me so I finally will be able to use my laptop ( dell latitude d620) again.

Thanks in Advance!

Please edit your question to add details about your wireless card. Open a terminal and run and post: lspci -nn | grep 0280 –  chili555 Aug 11 '13 at 15:21

1 Answer 1

Since the problem occurs with two different versions of Ubuntu and also with Windows XP, I suspect the router setup. How is the wireless configured? WPA2 and what encryption? TKIP or AES? AES is preferred. If possible, do not use mixed-mode WPA and WPA2. Is it capable of N speeds? Have you tried resetting the wireless to B and G only? Is it capable of both 2.4 Ghz and 5 Ghz bands? Have you tried disabling the 5 Ghz band?

I haven´t tried that but I´m also suspecting the router, my sister has the same problem. I will try it out and post my findings! –  Max Hogenkamp Aug 11 '13 at 16:26
