To JeremyB
excuse my return after 10 months of absence……only
i had installed with your help, the (AC 1300 Wireless Dual Band USB Adapter) with the sequent commands

Code: Select all

Code: Select all
sudo apt-get install git dkms
git clone https://github.com/abperiasamy/rtl8812A ... _linux.git
cd rtl8812AU_8821AU_linux
sudo make -f Makefile.dkms install

Code: Select all

The adapter works only at 2.4 GHz and not with 5ghz with the new rooter (Vodafone) (works with w10). In the list of wireless networks not appears the 5Ghz. Can i hope in a new help from you???

Thank you
