I had minor wireless problems in 10.5.1 (sometimes after a wake-up, wireless didint connect and i had to sleep/re-wakeup). Anyways, now i get disconnected once every 20-60 seconds. Its sooo bad. The wireless icon doesn't show it, but I can't access the net every x minutes. I'm pretty sure its the update, because I've never had this problem before. What can I do?
