From what I understand, the 1180 only supports WEP - but does that mean the Linksys or other new routers have to be configured for WEP and not WPA?

Everything on the network needs to be able to use the same security algorithm.  You cannot use WPA and WEP on the same network.  If you want to use WPA, then all network devices must be capable of using it.
