Possible problems with the downstream???

Im not sure if this is something to be worried about but from the research i have done i think it is,

this is my downstream table,

i am asking for help because i have been receiving a bunch of lost MDD timeout, with the error number 84020200 and a level 5 priority.

Re: Possible problems with the downstream???

Yep, your downstream power levels are too low and the downstream SNR is too low as well, probably why you are seeing the lost MDDs as technical infp is being lost from VM's servers to your hub.

It might be worth giving the coax cable from the hub to the cable entry point for obvious signs of damage and all connectors are hand tight. If you have an attenuator screwed into the back of the hub it would be worth removing it.

You will need to contact VM for resolution, either by waiting here about a week until a VM Forum Team Member picks up the thread, or give them a call on 150 from a VM line or 0345 454 1111 for a quicker response.

Re: Possible problems with the downstream???

Morning NadeRut,

 

Welcome to the community and thanks for posting.

 

Sorry to read you are having issues with your broadband connection.

 

As griffin mentioned, the downstream power levels and Modem SNR (signal to noise ratio) are too low and also the upstream power levels are too high at + 55 dBmV. For this I can arrange an engineer appointment for you and have sent you a PM (purple envelope icon, right corner) with some details for you to confirm please.

 

Hope to hear from you soon

Sam
