Here's what I have tried

# add wlan1
sudo iw phy phy0 interface add wlan1 type managed
# change MAC to be different from wlan0
sudo ip link set wlan1 address <different_MAC_from_wlan0>
# try to setup AP on wlan0 and STA on wlan1
sudo hostapd -i wlan0 /etc/hostapd/hostapd-5g.conf
sudo wpa_supplicant -i wlan1 -c /etc/wpa_supplicant/wpa_supplicant-wlan1.conf

The observations are

To connect to AP on wlan0, the password has to be provided again at the first or second time although it is correct all the time.
STA cannot connect
AP failed to accept client connection
wifi device access get no response

The short answer is yes.

It has been some time since I tried this so my memory is not fresh and I am currently in the process of moving with most equipment packed so my ability to check things out is limited.

With that said, here is the relevant statement from $ iw list

{ IBSS } <= 1, #{ managed, AP, mesh point, P2P-client, P2P-GO } <= 2,

total <= 2, #channels <= 1, STA/AP BI must match

Make sure both are on the same channel as I think that is the problem I have seen people run into.

Cheers

Is this issue solved?

Question: Is STA+AP concurrent mode supported in mt7612u ? #2

{ IBSS } <= 1, #{ managed, AP, mesh point, P2P-client, P2P-GO } <= 2,
