Hello,
I have read through every info i could find. But after almost three days of frustration i have to ask for help.
The aim is to add a Wifi dongle (TL-WN722N v1) to a GL-MT300N-V2-ab1 which should connect to a existing AP via a high gain antenna and extend the internet through the internal wifi device.
It seems the drivers (kmod-ath9k-htc) are installed correctly when i look at dmesg right?
[ 24.037798] usb 1-1: ath9k_htc: Firmware ath9k_htc/htc_9271-1.4.0.fw requested
[ 24.045381] usbcore: registered new interface driver ath9k_htc
[ 24.550536] usb 1-1: ath9k_htc: Transferred FW: ath9k_htc/htc_9271-1.4.0.fw, size: 51008
Then
rm -f /etc/config/wireless
wifi config
After it the new radio0 appears in my wireless config file as it should.
And now i have no clue what to do next. I wasn’t able to do anything with radio0. Whatever i do in /etc/config/wireless the new Wifi dongle doesn’t do anything. The light doesn’t even turn on or blinks.
When i install travelmate. I can use radio0 to scan networks. But other than that radio0 stays silent 
The Wireless tab in LUCI is not there. So how do i set things up?
This is how my wireless config looks like:

Wireless Overview:
I have read that people did this successfully. But how? How do i use/activate the new USB dongle? I couldn’t even manage to see the MAC address of the WIFI dongle in Network → Interfaces. Even when i change mt7628 to radio0 in the wireless config. Why??
For any help i would be happy to donate some money.
Thank you
ED
P.S.: In the config files i deleted the guest interfaces to make this post smaller and easier to read.
