A fault that follows one device across several independent networks makes the endpoint and its application configuration worth investigating. It does not automatically prove the hardware is defective, because the same account, source and settings may follow it too.
Record what remained constant and what changed. That is more useful than replacing routers on every network the device visits.

Define the repeated failure precisely
Note whether the device cannot join a network, cannot obtain configuration, cannot reach independent destinations or fails only in one player. Those stages lead to different support routes. A generic loading screen is not enough to identify a radio failure.
Keep the exact device model, software version and application version in the record. Do not infer compatibility from the manufacturer's logo alone. A browser or operating system can have different capabilities from the installed player.
Check that the networks are genuinely different
A phone hotspot and a home connection provide a useful comparison when the hotspot actually uses cellular data. Two access points behind the same router may still share the same internet path and resolver. Describe the topology rather than simply counting network names.
Use only networks and accounts you are authorized to access. A hotel or campus can impose registration requirements that make its failure different from the home symptom. Do not treat policy refusal as another clean endpoint test.
Separate endpoint and source constants
Try an independent supported internet function on the device. If that works across networks while one source fails, the source or application path remains a lead. If all independent tasks fail, inspect the device's addressing, time and supported diagnostics without inventing a cause.
Avoid clearing application data before preserving its configuration and error. A reset may remove account access and make the original comparison impossible. Use the developer's supported recovery steps when the evidence points to that application.
- Record the exact failed stage and versions.
- Describe each network’s actual upstream path.
- Compare an independent supported task on the endpoint.
- List account, source and settings that remained constant.
- Escalate with a recoverable configuration and concise evidence.
Choose the right support owner
A device-wide network failure belongs first with the platform or hardware support route. A player-only failure with other tasks working belongs with its developer or source operator. Account access may require the service operator separately.
The useful conclusion is that the symptom followed a defined set of constants across documented paths. It does not certify the device as broken or every network as healthy. That distinction prevents an expensive replacement from becoming the first untested experiment.
Useful answers
Does failure on a hotspot prove the hardware is bad?
No. The application, source and account may remain the same, and the hotspot has its own limits. Separate those constants.
Should I factory-reset before contacting support?
Preserve errors and recoverable settings first. Use a reset only when the supported procedure and recovery plan justify it.
