If it's not detecting your DVB-T device it means the driver for the device isn't available in your current kernel.
As for failing to scan for muxes make sure that you're entering the correct number of zeros, on 3.4 it accepted 6 digit frequencies on 4.1 it expects the freq in Hz so, something like 123000000 should work.
Remember to assign the network to the adapter and it's enabled, it will take a few minutes to start scanning, if you're still having trouble, post the system log and/or screenshots of your config here.
