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 | 307.5 | 214.1 | 10 |
| Mobile — your own SIM | 436.7 | 37.0 | — |
Do not plan on tethering here. Mobile upload (37.0 Mbps) is far below the fixed line (214.1 Mbps) — if the room WiFi fails, your phone is not a working backup for calls.
