Ok, so it might be my fault on this. I grew up with a dad that was a VP of IBM so I wasn't even allowed to say "Apple", but now that I've married an "Apple using wife" I now have to figure stuff like this out.... I've been trying to extend our airport network to no avail. This is the current set up: We have a Cable modem (by Cox Communications) that is plugged into a saucer airport. I was then trying to extend the network to my garage by using a brand new Airport express. It currently isn't letting me "extend the current network". When I "join a network" (my only option)I get errors on my IBM outside usually dealing with IP issues..... why would extending this with the express matter with the IP address?? We have had up to 5 computers just using the old saucer airport (including this same IBM) with no issues, but now that I'm using the express to access it and it won't work......a little help PLEASE!!!!!!!!!!!
