First, you need the Express connected to Ethernet. Make sure that the main non-Apple router is set to share a public IP address. Next, when setting up the Express, just set up its Network name and Password exactly the same as the network used by your non-Apple router.

Hard wire it if possible. Running it as a repeater means it has to send and receive each packet twice, which will slow your network down. Set it to a different name but same SSID as your main router, assign it a designated IP address (I use 192.168.123.254 for main router and .253 for secondary wireless), turn off DHCP to put it into access point mode. I've used a dedicated hardware repeater before and ultimately replaced it with a hardwire run. The speeds I was getting on the WLAN were pretty crappy when I was running through the repeater, and with broadband speeds now creeping up to the levels where it can saturate a 802.11g network that's a significant thing now. So, if you’re not up to buying the expensive mesh-network systems that are sold today, you can start a new DIY project and turn a router into a repeater. Even if your router isn’t from the same manufacturer as the router you’re currently using, don’t despair. You can use different routers as long as they allow this. To test your luck You don't need a repeater if you have an ethernet port, just a separate AP using the same wireless SSID. Plus, repeater's speed is usually halfed from the original source, this avoids that. Actually any wireless router that has the firewall and DHCP server disabled will work for you. By installing the free DD-WRT firmware on a router, you can turn it into a wireless repeater or bridge. This means that even devices that can't reach your main router wirelessly connect through
