Look at the mode setting, its says router NOT bridge as I noted to look for in post #6 above LOL.
Ha, indeed. So that's the default setting, and I admittedly did not update this earlier; just went right into WebFig and did the steps as I outlined in the first post:
1) Set up security profile
2) Turn off wlan1 bridge port
3) Add wlan1 DHCP client
4) Remove eth as DHCP client (which was based on your analysis of my original config)
5) Remove DHCP server (also a good catch by you that I originally missed)
6) Set up wlan1 as a station bridge with the given security profile and same SSID as my main router
Now, I set it up as a bridge on QuickSet, and then followed the above steps. After going back to QuickSet, the settings are *back on router*; so I obviously screwed something up in WebFig.
FWIW, yet another config:
Also, I noted in an earlier post you assumed I was wired between the two routers, but I am not.
