X1C7 WiFi issue

WiFi can disconnect from time to time (in Linux). This is the most annoying problem with the X1C7. It vanishes for some days, before returning.

See reddit discussion; Looks to be this bug, though in 2021 Iā€™m seeing more of the 0x707 bug.

As a workaround, I decided to use an external wifi card (AC600M USB WiFi Adapter) - but that also had its own connectivity problems from time to time.

Update (Sep 8,2021): This issue appears only on NixOS (as well as Ubuntu, and possibly several other distros), but not on Clear Linux.
