I have a new Zero 4k with latest vix on it. I bought a new wifi dongle with a realtek 8812au chipset which does both 2.4 and 5ghz (CSL - USB 3.0 SuperSpeed Wireless AC1200 Dual Band network adapter). I can connect to my 2.4 network just fine, but it just refuses to even SEE the 5ghz network when I try to scan. I did install the 8812au driver but this seems to have made no difference (it worked before installing it and does nothing different after installing it or after removing it again). It shows up as an "8812au wireless network interface" so it is definitely the right chipset.
Is the issue that vix just doesn't support 5ghz wifi or is there something else going on? I bought it specifically to use AC 5ghz because nobody else around here uses that except me, and loads of people use 2.4.
