Is it possible to split the radios between client and access point (master)?
I thought it would be possible from the LuCI Wireless page - but, after setting up the 2.4GHz radio as a client (wwan) the 5GHz radio always reports that it's 'disabled' even after hitting the 'enable' button and that button has switched to showing 'disable.'
This seems such an obvious configuration that if it were possible, then I would have thought I'd have found a how-to - but I've found none. If there's something under my nose, apologies; otherwise, confirmation it isn't possible would help me stop flogging this particular dead horse?
If you're using a DFS channel on 5 GHz you have to wait out the radar check (usually 60 seconds) before the AP will start up after restarting wireless. It isn't possible to restart only the 2.4 radio by itself.
Make sure to set the country code on both radios to your country for best wifi performance. By default with no code set, they will only do the limited set of what is legal in all countries.
