Ok, so I have 4 mac systems: iPhone, intel iMac, intel MacBook, and a iBook G4. All 4 of these connect wirelessly to my home network without any problems. When I go to my friend's house I get a connection timeout on my iMac and Macbook when attempting to connect to his wireless. My iBook (only one still running OS 10.4) and iPhone connect just fine. When I attempt to connect on my 2 systems using leopard, it asks me to enter his wireless password, but his wireless is not password protected, as my iBook and iPhone never needed a password to connect. Is this an issue with leopard that cannot be solved or is there a solution to this problem? I tried multiple things in the network settings, non of which worked. If anyone can please help, that would be great.
