I can't seem to get my wifi to connect to 5G. I'm in the US, my localization is set to US. iwlist channel shows 5G, I modified my wifi connection with band set to 5G. It never connects unless I set it to 2.4 or automatic.
OH I figured it out. I had to set my localization. "Set WiFi Country" I had done that before but it seems to have gotten forgotten. Maybe with an update. I'm connected to 5G now.
