All Wifi (on all antenna) are visible as "Mode:Client" in Lucy and unable to get Wifi working at all.
The build from commit https://git.lede-project.org/?p=source.git;a=commit;h=3a3564ead5e4cf2f6ff73302c1e680b5575079ec works.
A build from commit https://git.lede-project.org/?p=source.git;a=commit;h=8301e613655c2d95fa5430a1a57d92d966fdc70b does not work.

(I compiled and deployed more than 20 times to find the culprit)

Don't hesitate to request information.
I can build and deploy if needed.

I did some test.
And the "|| return" avoid running the command:
hostapd_ctrl="${hostapd_ctrl:-/var/run/hostapd/$ifname}"
And if not run, the wifi interface does not work.
For information mac80211_iw_interface_add "$phy" "$ifname" __ap return 233.

Hello,

I'm the author of that commit.

Both of the reported hardware are based on Broadcom platform. I'd guess Broadcom cards still do not support virtual wireless interfaces...

Please try applying the following patch to your tree.

--- a/package/kernel/mac80211/files/lib/netifd/wireless/mac80211.sh +++ b/package/kernel/mac80211/files/lib/netifd/wireless/mac80211.sh @@ -429,6 +429,12 @@ rc="$?" }
  • [ "$rc" = 233 ] && {
  •   # Device might not support virtual interfaces, so the interface never got deleted in the first place.
    
  •   # Check if the interface already exists, and avoid failing in this case.
