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

NetworkDownUpPing
Fixed broadband — what the WiFi runs on 235.6164.213
Mobile — your own SIM 126.729.0 —

Do not plan on tethering here. Mobile upload (29.0 Mbps) is far below the fixed line (164.2 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.

Where this listing came from
