Hello,
Noticed that the snapshot r15460-211fed5f49 results in LuCi displaying Generic 802.11bg for both radio 0 and radio1, under Wireless Overview.
It also displays (? GHz) and Bitrate: ? Mbit/s rather than actual figure for both.
Continually displays Wireless is not associated for both as well.
Channel width selection is also not displayed.
Apologies if this was posted in the wrong section.
Did you also update the feeds before building? The fix isn't in the main openwrt repo, but rather in the luci repo.
It certainly fixed the issue for me.
