I'm running OpenWrt SNAPSHOT builds on a Belkin RT3200. I've tried using DAWN with some success to optimise client connectivity to best signal, but it's quite heavy weight it feels. I'm looking for a lighter option, and it seems usteer is going to be an official feature.
my usteer config looks like this

list ssid_list 'mesh'
but clients are not being kicked either to new AP's, or between 2.4 and 5g radio.
Any guidance to fixing this would be very welcome.
Did you ever figure out an working usteer config for this? I have a Linksys E8450 and I want to do the exact same thing. Steer clients to 5GHz when possible as preferred but no amount of tweaking of my usteer config seems to help.
