I have been using ubuntu 10.04 for a while now, and everything has been working perfectly until three weeks ago. I've been having problems with my wireless, while other computers (with Windows and Mac operative systems) are still able to connect without flaw.
What happens is that Ubuntu never shows any notification of disconnection, but I start getting problems finding pages in my web browser. If I reconnect to the network my internet is restored.
I will be happy to provide any information needed for the solution of this problem. Please be as kind to explain how to obtain such information, specially if its Ubuntu specific.
Thanks in advance.
