This is a bit complicated. I have a dual 2gig G5 and the modem has packed so I bought an extreme base station with modem which works fine. Also bought an airport express to extend the range. I have to say the range of these products is pathetic. So I bought a Belkin Pre-N router. This is designed to take your broadband/DSL modem in the back plus has 4 ethernet ports. In 6 weeks or so I will have high speed wireless broadband but at the moment I only have dialup (rural Australia). So I set up as follows - Extreme base station into phone line - LAN ethernet on Extreme station to WAN connection on Belkin - ethernet port on belkin to G5 - result no internet on G5. Should I connect extreme to belkin via ethernet not WAN port? Or what? Haven't even tried to use express in house with this set up yet. Or should I justleave te Belkin on the shelf until I get the broadband?
