How to get Multiple SSID to work on DD-WRT

Sep 16 2009

This is a great tutorial:

I have seen several HowTos, tutorials, and forum posts about how to setup multiple (B)SSIDs using DD-WRT and although most of these write-ups indeed helped creating multiple SSIDs, none gave me an actual working virtual SSID. Most of the time I wasn’t even able to connect to the new virtual interface and in those rare occassions that it did connect, I never got an IP address. The reason none of these write-ups work, is because they are all based on the same base tutorial which, for one reason or the other, no longer works reliably.

I took all these write-ups and figured out what is needed to get it to work again. The following HowTo is what worked for me on my Linksys WRT54GL v1.1 and Linksys WRT310N. It created two BSSIDs, each with their own MAC address so any device is able to connect to either BSSID without getting utterly confused. The main BSSID has access to the internet and to your local network. The second (virtual) BSSID only has access to the internet.
