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 | 925.2 | 715.8 | 4 |
| Mobile — your own SIM | 185.9 | 19.8 | — |
Do not plan on tethering here. Mobile upload (19.8 Mbps) is far below the fixed line (715.8 Mbps) — if the room WiFi fails, your phone is not a working backup for calls.
