I have a "router" and a wifi "repeater" (using relayd), both running latest LEDE.
The repeater has one SSID running as AP, and another SSID running as STA and connected to the router. The AP SSID on the repeater shares name and password with the AP SSID on the router, so clients can easily connect to either the router or the repeater. So far, pretty much standard configuration.
The STA SSID on the repeater normally connects to the AP SSID on the router, but I guess it could also connect to the AP SSID on the repeater itself, and obviously I do not want that. So the STA SSID in the repeater is configured to connect to the specific BSSID of the AP SSID on the router.
However, the router has several SSIDs configured on the same radio, so the BSSIDs change on each reboot; when this happens, the repeater can no longer connect to the router.
Has anybody faced this issue before? How did you solve it? Thanks!
