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
