Recognise the connection stage
A hotel or campsite Wi-Fi network may allow the box to join its wireless network before granting internet access. Manhattan’s Aero help describes a browser-based captive portal at that second stage. A successful Wi-Fi connection therefore does not establish that the box can reach online applications.
Its help says Aero’s www browser itself needs an internet connection to open, so it cannot be used to complete that initial portal login. An error before the browser opens is different from a normal webpage failing after internet access has already been granted.
Do not assume another device’s sign-in transfers
Manhattan says signing in on a phone or laptop does not unlock Aero on these networks because portal access is tied to the individual device. Keep the box’s network state separate from the phone’s successful hotel browsing test on that device.
Use only connection methods permitted by the network operator and the account supplying them. The manufacturer describes a personal mobile hotspot as an alternative route without a browser login page. If considering an existing hotspot, check its allowance and expected viewing duration rather than treating the phone’s successful connection as unlimited free broadband for the box.
Check the programme’s location separately
The same help page warns that Freely and most UK catch-up applications are restricted outside the UK. A box successfully online while travelling therefore does not establish that a particular UK programme can be played at that location.
When asking for help, distinguish joining Wi-Fi, obtaining internet access, opening an app and receiving a programme-location message. Include which stage fails and the intended connection route without sharing a room number, password or portal code publicly. This makes the request useful to either the network operator or Manhattan, rather than resetting the whole device for a documented login-stage limitation.
