Question 1

What are the advantages of open source DD-WRT? Is DD-WRT just user interface software or is it firmware as well?

Accepted Answer

ddwrt is a Linux distribution that is for use on WiFi routers. It includes a pretty fantastic web user interface, but the primary advantage is that your router is running Linux, whose network stack is rock solid and battle tested. For someone that's just looking for a normal router this product is awesome because it works. I haven't had to power cycle it even once. For someone looking to tinker, ddwrt is awesome because of what it can do (fancy routing, VPN, stats reporting, network partitioning, QoS) and how it can be extended with other community plugins you can download. And at the end of the day it is just Linux -- ssh and tinker to your hearts content.

In the early days, getting ddwrt on a router was a pain and involved buying one of a few supported routers and then manually installing the firmware. Now that buffalo is on board and shipping the firmware native its a pretty painless experience and I can really recommend it to users at all skill levels.

Hope this helps. :)

Question 3

Is it compatible with Motorola NVG589 (AT&T Uverse install)?

Accepted Answer

Technically any router is compatible.  You just have to set your Motorola gateway for IP passthrough.  Then set the internal router (ie the Buffalo router) to get its WAN IP automatically via DHCP.

There are guides out there; just do a search for "How to put the Motorola NVG589 in bridge mode"

Good luck

Question 4
