Broadband help

mikeyb200 · ‎24-10-2025

I'm getting periods where my router (Sagemcom Fast 2) frequently disconnects the broadband. It'll run fine for a few weeks, then we get another episode of instability. We're in one now, hence this post.

Running the TT line test shows no problem with the line - instead it suggests there are Wifi connectivity issues in the house. There aren't!

Looking in the Router Admin, it always shows the Downstream Noise Margin as 0dB. Surely this is the problem - I've always understood the minimum stable noise margin to be about 6dB.

So is it the line or the router? The router has already been replaced by TT twice before - so we're on our third one since moving here 3 years ago.

All very frustrating!

Hi @ferguson , sadly no fibre here yet. Hopefully arriving at some point during 2026, so I'm just trying to soldier on with this set-up until then.

Wise move. I'm stopping indoors with a can and the darts on the telly! 🙂

Sure.

Thanks. I'm off down the pub now!

Do you not have Full Fibre available in your area yet?

OK, but maybe the router reset has helped, let's see. Just post again if you have any further issues.

Yes. And it might behave for an hour, or a day, or a week.

But a TT line test never shows any problem.

So is it connected now?

Been there, done that. It's driving me nuts!

ferguson · ‎24-10-2025

Just keep an eye on it. If it disconnects again, then try connecting at the test socket with a plugin microfilter.

.... proceed?

mikeyb200 · ‎24-10-2025

@ferguson Yes, working currently. But the underlying issue is, I suspect, unresolved.

Do you have any suggestions how I

ferguson · ‎24-10-2025

Yep, if you @ mention me as you have done here I will pick it up, within reason! So all working OK just now?

OK I'm back to 'normal'. Are you there, @ferguson ?

mikeyb200 · ‎24-10-2025

Thank you. I could not make the person I was dealing with understand that!

I'm resetting stuff right now...

ferguson · ‎24-10-2025

It's not for me to mind, I am just a punter the same as you! I guess the support team have knocked off for the weekend now. Changing the WiFi settings to those of your choice will have no effect on the underlying external connection.

mikeyb200 · ‎24-10-2025

Ah, so you don't mind if I put the Router back as it was?

ferguson · ‎24-10-2025

Is the router still connected? You will need to reset SSID and password from scratch sadly.

So what happens now?

ferguson · ‎24-10-2025

@siphosethu-TT

Forgive me, but it would have been nice to at least ask if a remote reset was agreeable, rather than just going ahead with it.

Everything in the house has lost Wifi connection except my Mac, which 'knows' the original SSID and PW of the router.
