@Steve40th396,

The BSSID will be assigned automatically by the network router. If you are unable to connect to the network, make sure that you have WDS enabled as this is the feature that affects the BSSID. I would try to configure the SSID(to be bridged) field manually, and also ensure that you are configuring only the 2.4 Ghz if they are not using the 5Ghz band at all.

In RE mode, when you hit scan, you can see the BSSID of the networks visible to the travel router. I would try to copy one of these if the automatic configuration is failing. I believe that the BSSID is simply the name of the network that you are trying to connect to, however, the travel router scan function delivers this in ipv6 form rather than using the friendly name of the network. This shouldn't matter but may help if there is an incompatibility between the networks.
