Measured on this block in Apr-Jun 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
| Network | Down | Up | Ping |
|---|---|---|---|
| Fixed broadband — what the WiFi runs on | 380.4 | 361.4 | 21 |
| Mobile — your own SIM | 63.8 | 20.1 | — |
Do not plan on tethering here. Mobile upload (20.1 Mbps) is far below the fixed line (361.4 Mbps) — if the room WiFi fails, your phone is not a working backup for calls.

Country- and ISP-level outages, not hotel-level. A national outage takes the hotel with it; the hotel's own router failing will never show here.
