Hi all, I have been using my mbp on my wireless network without problems for almost two weeks now. But during the last days I have experienced an extremely unreliable signal from the network. In the past it was always near the maximum quality, but now it just revolves between maximum and minimum, and whats worse, it drops the signal regulary, this is extremely annoying for applications like irc and msn. I can't think of anything that I changed to either my macbook, router or the environment recently so I have no idea what is jamming my signal. I did install a torrent client, but I also have the problem when the program isnt running. ( is there an easy way to monitor network activity in os x? ) On a related base: I wasnt able to connect to my friends wep-secured network even after literally copying the wep key. We tried several times but always got a connection error. Removing the wep security was the only thing that worked. Both my psp and sony laptop were able to connect using that same wep key.
