Ping-Ke, Happy to help, answers below: 1. Yes, the kernel shows the following (that's why I started this email thread): [ 3.541494] rtw_8821ce 0000:03:00.0: Firmware version 24.8.0, H2C version 12 [ 3.558760] rtw_8821ce 0000:03:00.0: rfe 6 isn't supported [ 3.558890] rtw_8821ce 0000:03:00.0: failed to setup chip efuse info [ 3.558893] rtw_8821ce 0000:03:00.0: failed to setup chip information 2. Unfortunately, I don't have a Windows 10 setup readily available 3. The module is soldered onto the motherboard, so I can only show you one side. Picture is attached. It looks like it's produced by CDTech (China Dragon?): https://fcc.report/FCC-ID/ROW-61821CE/5189720.pdf There are two antennas, one for 2G, another for 5G shared with Bluetooth. Maybe the type 4 driver will work for it out of the box?
