Establish the change record
Note the router model, previous version if actually known, current version and update time. Keep the original symptom and last known working observation. Do not invent a previous version from memory or a support page for a different hardware revision.
Record whether the router restarted, changed wireless settings or required a provider reconnection. Other household events may have occurred in the same interval. A media source can also recover or fail independently while local equipment is updating.
Check the configuration that serves the television
Verify the active wired or wireless path, address allocation and ordinary external access. If the network uses a mesh or second router, record its role and whether its upstream connection changed. A familiar Wi-Fi name does not establish identical band, policy or topology.
Use the exact vendor's release notes and support guidance for the installed version. A reported issue affecting another model is context, not evidence that your router has the same defect. Keep any claimed fix tied to the documented hardware and firmware.
Make one supported comparison
If the vendor identifies a relevant setting, preserve its original value and test a documented correction. Keep the player, programme and location unchanged. Do not combine a factory reset, DNS change, new player and firmware experiment into one untraceable action.
An illustrative report is “ordinary wired browsing works after the update; only the wireless television path disconnects; current settings show a different band arrangement.” That narrows the question. It does not prove the whole firmware is broken or that every customer should roll back.
Leave rollback decisions with documented support
A downgrade can have compatibility, recovery and security consequences. Use only an explicitly supported vendor or provider process if it is actually recommended for the issue. Do not install an old binary from an unfamiliar file-sharing site.
After a correction, retest the original viewing task and ordinary household functions. Retain the version and outcome in a non-sensitive maintenance note. If a specific media resource still returns the same server refusal on every path, preserve that separate account/source question rather than attributing it to the update automatically.

Should I disable updates because one session failed afterwards?
No such conclusion follows from timing alone. Investigate the actual change and use supported maintenance controls.
