I currently have a home network with a DLink DI-655 wireless router. The coverage is very good through most of the house, but there are some weak spots. I'd like to connect my old DLink DI-624 wireless router (hard wired to the DI-655) and use it as a wireless access point. I'm pretty sure this is possible, but I don't know how to configure the routers so they play nicely together.
Some of you guys are way smarter than me when it comes to this stuff, so I'm throwing myself at the mercy of your wisdom.

P.S. I got the DI-655 based on suggestions from the group, and I couldn't be happier with it. Set up was a breeze, and I haven't had any crashes or connection issues in the several months that I've had it. I would highly recommend it. My only complaint is that I can't find a mini-PCI wireless 'n' card for my netbook to take advantage of the higher wireless speed.

P.P.S. I absolutely love me Asus EeePC netbook! It's my new favorite toy.

It is pretty easy. The main issue will be the initial setup as your old box will have retained your last config. The instructions below might not be 100% accurate for your setup, but they should give you the gist of what you have to do.
1. Disconnect your computer from your new box
2. COnnect it to your old box on one of its LAN connections (the box should still be configured to provide DHCP addresses)
3. Go into its configuration screen (probably 192.168.0.1 or something like that)
4. Find the appropriate menu and DISABLE DHCP (probably 'Network Settings' on the left side of the configuration page and 'Setup' on the top side; then UNCHECK the 'Enable DHCP Server'
5. Reboot the old box.
6. Reconnect your computer to the new box.
7. Connect one of the LAN ports of your old box to one of the LAN ports of the new one.

Wi-Fi clients should see a straight Ethernet network accross both boxes. The LAN ports and the Wi-Fi ports are as if connected to the same physical switch. The fact that only your new box allocates IP addresses will ensure that your applications will understand to which box to send packets going to the Internet.

Hope this was enough details. Do not hesitate to ask if they did not work.

Yeah, he's right. The only thing you really have to do is turn off the DHCP server on one of the routers.

Thanks, I'll give it a shot. Sounds pretty simple. I was expecting something more involved.
