M200 slow upload of 1.5 mb and dropping out

My hub keeps dropping connection and the upload speed is 1.5mb download varies between 20 and 150mb, was getting a raft of t3 timeouts but after rebooting hub a number of times this has gone away , Hub refuses to go back to factory settings though.

here is my bqm

Upstream looks a little strange though

Re: M200 slow upload of 1.5 mb and dropping out

All four upstream channels should be at 64qam, 3/4 of yours are not and are almost certainly impacting your upload speeds..

post the full tables from downstream, upstream and network log, someone who understands it all will, I’m sure, comment on potential causes.

Re: M200 slow upload of 1.5 mb and dropping out

Im no expert on the docsis side off things but I believe your upstream power should be below 40 - it’s too high on all channels and suspect that you’ll need an engineer to put it right.

I wonder if your local cabinet is open to the elements?

Do you have any neighbours with VM you could check with?

Re: M200 slow upload of 1.5 mb and dropping out

Carl I don't know but wouldn't be surprised most of them around here are held together with tape ?, what I want is for virgin to accept that there is an issue whether that issue id the weather or contention.

either as I am not getting the upload performance I need to work , and trying to get the helpdesk to answer or raise a fault is bad enough as all I get is cant see anything our end, that's not what BQM is showing and not what the Hub is showing,

Having Mixed Modulation types is not going to work it should be 64qam across the board not 16 and 64 and like last week 8 16 and 64.
come on Virgin do something
