I have been using OpenWRT for a while on my single-port HooToo TM06. My use case is as a portable wireless AND wired router, using the wireless CLIENT as WWAN (internet connection) and wired ethernet as "WAN" (no internet), both routed through the second wireless MASTER SSID that I connect my laptop to. This works great, until I forget to disable the wireless CLIENT before leaving a site, and then am unable to reconnect to OpenWRT because the MASTER SSID isn't broadcast unless the CLIENT SSID is connected.
This always necessitates a reload of the firmware, as the reset button on my TM06 doesn't enter OpenWRT recovery mode (at least I haven't been able to get it to work).
For a while I settled on a separate USB wireless radio that broadcasts another MASTER SSID at all times, since it doesn't have a CLIENT to connect to, but if I forget to remove the USB radio, it drains the battery on the router, (USB port is powered as a power-bank even if router is off). This is very frustrating.
Is there a way to ensure the MASTER SSID is always broadcast, even if the CLIENT SSID is not associated? Or maybe just a way to disable the CLIENT SSID if it doesn't connect after some time, so that the MASTER SSID can then begin to broadcast?
