First time out with this ROM (r42039 on wndrmacv2) for me and it's looking fine with one exception, so I thought I'd ask here if there's a known issue before burning too much more time on figuring this out.
In short, no matter what I do, 5GHz (Atheros AR9220 802.11an (radio1)) never shows up outside of the router (i.e. no SSID). 2.4Ghz (Atheros AR9223 802.11bgn (radio0)) always does. They're each configured as similarly as possible, and I've deleted/recreated many times, as well as trying 5Ghz alone. Specific channels vs auto don't seem to matter (no other 5Ghz devices in range anyway). It's enabled in the UI, so this is puzzling.
The log even shows the wlan1 link "up" just as it does wlan0.
Edit: I should add that my phone, which is my wifi client, is 5Ghz capable. It uses the Broadcom BCM4330. A tablet that I have also uses that chip. However, a laptop I have uses a Ralink RT2870, which like the Broadcom supports 5Ghz and also can't see the SSID.
