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 | 150.3 | 133.5 | 8 |
| Mobile — your own SIM | 319.8 | 51.8 | — |
Do not plan on tethering here. Mobile upload (51.8 Mbps) is far below the fixed line (133.5 Mbps) — if the room WiFi fails, your phone is not a working backup for calls.
