Hi, came across this post and was able to get the settings changed in etc/config/wireless. It helps if you have already attempted to set up some kind of repeater connection so you can use the existing settings as a guideline, but that’s purely an individual thing, and not necessary to get things working.
One important thing, though, and a question - how do I get the configuration to stick between reboots of the router? It appears that after each reboot, the 5GZ radio is switched off, and there are no options to reconnect, as there are in the GUI - what settings file controls that, and where are the “saved stations” stored?
Thanks,
Joe
