No Wi-Fi Adapter Found : 3 Delta, Ubuntu18.04

userHead Tomohiro.Suzuki 2022-12-01 11:35:20 677 Views0 Replies



I installed Ubuntu18.04 on LattePanda 3 Delta, and found Wi-Fi is not working at all, even though wired connection works normally.

Wi-Fi icon on upper-right corner of the Desktop is not shown. Wi-Fi settings window says "No Wi-Fi Adapter Found".


Wi-Fi module on 3 Delta seems to be AX201D2W, so I tried installing the firmware for "Intel® Wi-Fi 6 AX201 160MHz" from this page:

but nothing changed. (Actually the same firmware files were already there.)


Any advice to fix the problem?
