I recently got a broadband connection, complete with wireless modem. Since then, I have not been able to connect my Macbook to the wireless network at all - even after seeing the network and inputting the correct password. I get different errors - sometimes it's 'connection timeout', or otherwise a simple 'connection failed'. Once I even managed to get connected... for about five seconds. It's not a problem with my modem, as my other wireless devices connect fine. It's a known problem apparently, and I've looked all over for solutions (some say it's a keychain problem with the password) and tried everything I can think of, and I still haven't managed to sort it out. Ethernet cable works fine, but it's quite inconvenient for me to use on a regular basis. Can anyone help at all? I'm considering buying another router and connecting it to my existing modem, would that help? It's the only problem I have with my Macbook, so any help/ solutions will be greatly appreciated. Edit: I should point out that I had these problems on Tiger, and recently upgrading to Leopard (and installing all the latest updates) doesn't seem to have fixed the issue.
