if you arnt being issued an ip adress (i take it this is the case wit yourfriends machnes) then double check the mac address you gave the wireless router is the one for your wirless device, and your not on deny rather than permit or soemthing daft. if your freinds are getting ip address okay, then maybe your linux box isnt asking for one, do what handdog says!! just to see if things will work though, try specifying your own address. look at your freinds network config, and mick thiers, except the ip address. if they are between 192.168.1.100 and 192.168.1.105 or sopmething then go for 192.168.1.152. see if you can connect then.
