Are support talking rubbish?

Had a lot of packetloss so rebooted the Shub3 and it wouldn't lock signal, spoke with the live chat and they claim it's due to a reverse path block put on due to noise coming from my property.

That would make sense if the hub didn't manage to reconnect whilst I was in the middle of the coversation and seems to be seeing all 4 upstreams

Edit: TV signal is all over the place and rebooting the Shub it spent a long time looking for signal, I do wonder if there's an engineer around here somewhere having a fiddle.

My original question is however if I'd been RP blocked then surely the Shub wouldn't be able to connect at all?

24 139000000 5.8 38 256 qam 1


Power levels are a bit high esp on 22 23 and 24 . almost reaching the maximum of +6 but apart from that the rest looks kinda normal

Re: are support talking rubbish?

Might be worth reposting them now the area fault has cleared, certainly the packetloss is gone.

It was losing lock on a lot of the channels earlier.

Re: Are support talking rubbish?

It doesn't look healthy to me. The Post-RS errors (packet loss on the downstream) are a worry unless they are historic and not rising.

Also, the DS power levels are askew. Although the values are nowhere near out od correct range, the lower frequencies should require less power than the higher frequencies - and that's not what happens in your case. Either the cabinet amplifier is faulty or incorrectly sloped (you can Google that!).

Re: Are support talking rubbish?

can you reboot the shub to clear to the rs errors and then monitor it over the next 24-48 hours.

Just rebooted the Shub to clear the error counters, power levels are still a bit out but i'm not seeing the terrible packetloss I was when the fault was present (I'd started a CQM graph it was horrific)
Think most of those post RS errors from before were when the fault was occurring.

Re: Are support talking rubbish?

Good. Apart from the incorrect sloping the stats are good. Being well in range, the slope doesn’t matter for you, but it would for customers further away from the cabinet.
