I have not tried it with the HooToo, but have with another MT device. I have 2 radios in mine, but still expect it to work. I will try, but it may be a day or 2.

Please post your wireless, firewall, network and logs.

You might try

Disable wifiMgr

restore a known good config

edit the wireless file (making sure the AP is the first iface)

enable wifiMgr

reboot
