Massive Signal Drop BN Help!

Hello,

Woke up this morning, and we have seemed to have had a massive signal drop overnight. Two of our virgin TV's are not displaying some channels, and our router has had a -15dBmV drop giving us barely any speed and very dodgy connections.

Gonna give Virgin a call this morning, but thought I'd post here as I've had more help from here in the past.

Hopefully this will get sorted quick, the kids need the internet for school.

Thanks

Re: Massive Signal Drop BN Help!

Hello

That is the lowest I have seen for sometime.

I would go around  and make sure that all coaxial connections to all VM equipment are finger tight, then power of hub for 30 secs and back on, if those signal levels are still below -6 then an engineer will be needed.

Hello,

Thanks for the reply.

No devices have been moved, all connections seem OK, and rebooting the router did not work. Could be one of the splitters has failed? Internal break in a cable? Problem at the cab?

Will wait to hear what Virgin say on the phone.

Re: Massive Signal Drop BN Help!

Is there an attenuator fitted to the back of the hub?

Re: Massive Signal Drop BN Help!

No attenuator.

The Hub is at the rear of the house, from the front of the house it goes through 3 splitters to get there (one powered). We have also got four Virgin TV's (three of which are not displaying channels correctly). The only telly that is working is the one that comes directly off the first splitter, although the diagnostics info page for that Tivo box says signal is only 80%.

Just got through to Virgin and we've got an engineer booked.

Just to update.....

Just had a text from Virgin saying that they are putting our engineer visit on hold whilst they investigate a network issue.

So I'm guessing that this problem could be further upstream somewhere?

Yes could be.

They suspend engineer visits if there’s a local/network issue as there’s nothing a home visit can do to cure it.
