I have a Raspberry Pi 3 B that runs Debian 8.0. So far I didn't install anything and only run raspi-config.
I want to use the onboard Wifi card, and I can connect to my 2.4Ghz Wifi, but none of the 5Ghz ones.
iwlist wlan0 scanning just doesn't show them up. Also, the bitrates are only max 54Mb/s:
Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s 9 Mb/s; 12 Mb/s; 18 Mb/s Bit Rates:24 Mb/s; 36 Mb/s; 48 Mb/s; 54 Mb/s
Do I have to enable something?
