Computer was offline because it was on guest Wi‑Fi and an inactive Ethernet wall port
The machine had no working internet after the move. The Ethernet cable was moved to an active wall port, the computer was connected to the main Wi‑Fi, and internet access was restored; dock firmware and Type‑C USB firmware were also updated and monitor settings were checked.
Killed once by someone from XL.net, on 2026-03-17.
