I have a 2-router setup currently, with the 2nd router acting as a remote WAP: Main router - RT-N66U - Tomato Shibby 112 AIO-64K 2nd Router - E1200v2 - DD-WRT v24-PreSP2 Build 21061 Main router is broadcasting my main SSID on LAN0, as well as ethernet ports 1-3 are on LAN0 Main router is also broadcasting a guest SSID on LAN1 and ethernet port 4 is also on LAN1 2nd router's WAN port has been bridged to the LAN and is attached to Main router's port 4, effectively putting the 2nd router (WAP) on my guest network. 2nd router is set up and running and working perfectly as a WAP, several hundred feet away from the main router. My problem is this: The main router's guest SSID stops working when the 2nd router (WAP) is plugged into port 4. It continues to broadcast the guest SSID, but nothing can connect to it. The moment I unplug the 2nd router from port 4 of the main router, I can connect and use my guest SSID. I'm at a loss as to what could be causing this issue. If I plug a regular wired client, such as my laptop, to port 4 of the main router, it correctly gets assigned an IP from LAN1 and functions, and my guest SSID also functions. It's ONLY when the secondary router (WAP) is plugged in that the guest SSID stops working. I'm thinking there is some kind of service running on the secondary router DD-WRT (WAP) that is causing this, or something I haven't enabled that needs to be, but I can't figure out what it is. I would just put Tomato on the 2nd router, but there is a specific script I'm running on the WAP that requires DD-WRT.
