Measured on this block in Jul-Sep 2026 — the ceiling the hotel's WiFi sits under. Shared WiFi, captive portals and per-device caps only make it slower, never faster.

Fixed line vs mobile

NetworkDownUpPing
Fixed broadband — what the WiFi runs on 336.5200.58
Mobile — your own SIM 84.614.7 —

Do not plan on tethering here. Mobile upload (14.7 Mbps) is far below the fixed line (200.5 Mbps) — if the room WiFi fails, your phone is not a working backup for calls.
