Upload speed not reaching 104 & packet loss on BQM

[Sauce245]

Hey all,

I posted this on the end of another thread but have had no response from VM so wondering if any of the community have opinions on this. Copied from my post:

"I moved to a new flat with Gig1 and the flat has VM ports in 3 rooms. Looks like the other ports are fed by coax from the master port, I guess they were used for VM TV by the previous tenant. I have plugged in the cable feeding the bedroom port from the master port, and plugged the router in to the port in the bedroom, it works in terms of speed (the upload seems to struggle to get above 85Mb though), but I keep seeing random packet loss and noise on the BQM, especially when running speed tests.

Would you mind taking a look at my config to see if using this secondary port in the bedroom is OK? I haven't actually moved in fully to the flat yet so haven't been able to properly test it with online games or anything like that."

I am not even at the flat and seeing packet loss on the BQM:

Is this normal? To see this when the connection is not even being used? It seems to always coincide with a spike in latency. I will when I properly move be putting it in modem mode and hooking up a BE98 but I don't think that will have any effect on what I am seeing on the BQM. I also realise looking around on the forums that my BQM is probably about as good as it gets for VM minus the packet loss...

I am coming from a flawless FTTP connection from you who, where the BQM is flat 99% of the time. I am going to miss that 😔

Power levels and such:

Once the test begins click on: Run full test to include: Latency, Jitter, Packet loss & Upload speed

The speed at the Hub should reflect your subscription.  

Do share a screenshot of the Full test.

Your upstream power levels are out of spec, and it appears you are in an area that does not currently support DOCSIS 3.1 upstream, so 6 3.0 channels are being used instead, which should still be sufficient for 104Mbps.

You also have a SNR issue on a couple of downstream channels.

Engineer visit required.

Tried to run it just now but kept getting an error, will try again tomorrow.

Ah...OK. Thanks for looking at it. I guess I will need to hop on the phone to VM then...

Or wait a few days for a reply on here.

None of the coax connections can be left open. Either fit a termination connector on the far end, or remove it from the splitter.

Seeing 85 Mb/s on the upstream is what happens when there are only 4x 3.0 Upstream channels.

Could it be of the 6x 3.0 Upstream channels that are connected, only 4 are bonded ?

[Sauce245]

Seems plausible...

SamKnows test shows the issue with upload speed:
