Best solution for single AP band steering

Installing and Using OpenWrt
1

If I have a single router with two bands using a same SSID. Will usteer or DAWN help for roaming or they only work in multi AP setup? Is enabling 802.11r alone enough?

11r has nothing to do with roaming as such. It is just faster roaming when client supports it and intends to roam.

you need wpad-mbedtls in place of wpad-basic-mbedtls and usteer to enable roaming hints for devices not willing to roam on their own. dawn is for more complex setups.

Could you provide an example config for this setup? usteer recommends:

roam_scan_snr '-65'
signal_diff_threshold '8'

But since there's only one AP, roam_scan_snr '-65' alone should be good?

just do not change any parameter at all.
