Hello everybody! Sorry for my bad english, this is google translate I have Lenovo x240:   Many thanks to Klem. He removed the WWAN and WLAN whitelist in my x240 bios. I replaced WLAN: old ac7260 with new ac8265 - super !!! I wanted to put ax210, but unfortunately it haven't a drivers for Windows 7, for Windows 10 only. Replaced WWAN: old em7345 with new em7455 - problem: when turning on or restarting the x240, a sound signal and an error appear: 2101
