Superfast Hub Randomly Reboots During Movie Streaming, Any Fix?

[markpousee]

Hi BT Community, hope you're all doing well!

I’m Mark *****, and I'm having a frustrating issue with my BT Superfast Hub (Plus), every now and then, especially when I’m streaming movies in HD (like Netflix or Prime Video), the router randomly reboots on its own. The stream buffers, the lights flicker, and I'm suddenly offline for a minute before everything goes back to normal.

Here’s what I’ve already tried to fix it:

• Restarted the Hub manually and ensured firmware is up to date.
• Swapped power socket and adapter, still happening.
• Checked logs, just shows an abrupt restart, no errors.
• Reduced network load (no heavy downloads during streaming) but it still reboots.
• Tried streaming from different devices (TV and tablet), same issue occurs.

Has anyone else encountered this? Any suggestions, link like specific Hub settings to tweak, hidden logs to check, or known firmware issues to avoid? I’d really appreciate your insights or any workaround that’s worked for you.

Thanks so much in advance!

Mark ***

Are you on FTTP or FTTC ? , if FTTP, what happens to the lights on the ONT , does the LOS light come on however briefly, if FTTC , search REIN and SHINE , this is basically electrical interference that knocks the ADSL/VDSL sync out , causing a reboot , dodgy electrical devices , even if they appear to be working OK can cause this , things like central heating pumps switching on , if the suppression on the device is poor the electrical ‘noise’ as it switches on , knocks out your hub , so does your hot water pump switch  on around the same time as these events , ( or anything else electrical for that matter )

unfortunately it’s not just devices in your home , it could be someone near by , you may remember a case where an entire village was losing broadband at the same time every evening , AFAIR ,  it turned out some old chap with an ancient TV , switched it on at 7pm , the electrical ‘pulse’ it generated knocking out everyone’s broadband , as you can imagine that took a lot of ‘investigation’ as the old chap was unaffected himself .
