Asus T100HA Wi-Fi

Postby 5unbeam » 2020-06-04 06:32

Hello!
I've installed Debian 10.4 Gnome nonfree on my laptop.
Hardware supports 5MHz wifi, but I can connect only to 2.4MHz.
How do I turn on 5MHz?
I did everything mentioned in wiki https://wiki.debian.org/InstallingDebianOn/Asus/T100HA
It works fine in Mint. More stability is also an advantage for me. Is it possible to use the same solution as it is in Mint?

That's an old guide that recommends installing an outdated, unsupported, vulnerable kernel version and also provides a non-working command string to copy the wireless firmware description file from the motherboard NVRAM to your system. The OpenELEC download isn't needed any more either because Debian now have a package for that firmware.

Ensure that your running kernel is the latest Debian stable version and run
Code: Select all
# apt install firmware-brcm80211
# mount -t efivarfs efivarfs /sys/firmware/efi/efivars
# cp /sys/firmware/efi/efivars/nvram-74b00bd9-805a-4d61-b51f-43268123d113 /lib/firmware/brcm/brcmfmac43340-sdio.txt

If that doesn't get 5MHz working then check dmesg(8) in Mint to see what's happening there, compare that output with your Debian system.
