Got a new 4k today. Unboxed, connected to mains, TV, and Ethernet. Updated to latest. So far everything is fine. BUT it can’t connect to my Wifi because the SSID is not listed. I got a 2,4 GHz with a good signal. A lot of other stuff can onnect to it.
The SSID is @homeorsimilar
Ok we had some debate on the topic and yes can set it up to support Channel 13.
Install crda sudo apt-get install crda.
Add your 2 digit country ISO code into /etc/default/crda REGDOMAIN sudo nano /etc/default/crda
Then reboot. After reboot check with iw reg get if it is set correctly
