setup wise.
don't use any CDs that come with the router. access the routers settings via the web IP. as long as its set to obtain IP via auto or dynamic all you need to do is stick the SH into modem mode then link a ethernet cable. in modem mode the ethernet port on the SH closest to the white cable input is the 1 to use.. then the other end goes into the routers WAN port.
new routers have a password already created for the you wireless network but you can check that out manually via tabs within settings or a quick install process.
