Part's of Uddingston been on 4 for a few months.

Re: 4 upstream channel bonding - post here
 

What part are you in. We are in ML3

Re: 4 upstream channel bonding - post here
 

ML6

Re: 4 upstream channel bonding - post here
 

Only 2 in ML5.

Wondered why I had a ton of pre and post errors on my downstream channels and checked my upstream and I'm now on 4 channels.

I had noticed my modem rebooting and such late at night so I guess they were doing some work.

More of Uddingston on 4 channels.

Staverton now on 4 upstreams (64QAM)

Re: 4 upstream channel bonding - post here
 

One of the things I've noticed on my 4 channels (for the past couple of years) there is always 1 channel at 16QAM (the others being 64QAM). Usually it's 25.8MHz that's at 16QAM. But today, that channel is at 64QAM and another channel is at 16QAm. In due course it'll revert. The VM forum bods can't give me an explanation for this.

Seph i used to have this issue but now touch wood all seem rock solid on QAM64.

Could it be noise?

Re: 4 upstream channel bonding - post here
 

Not in my opinion, Alan. It moves; yesterday it was 32.6 MHz at 16QAM, today it's back to 25.8 MHz - the others being 64QAM. Two years of noise would have got fixed by VM, imo.

Re: 4 upstream channel bonding - post here
 

Mine are all 64QAM now.

Seph if they can leave people over subscribed for that amount of time then surely they can leave some noise on the network lol.

Re: 4 upstream channel bonding - post here
 

The modulation on my device seems to be all over the place since it moved to 4 channels.

Currently it's

1 46200000 42.5 5120 32 qam 9
2 32600000 43 5120 64 qam 11
3 39400000 42.8 5120 64 qam 10
4 25800000 41.8 5120 32 qam 12

Yesterday it was a combination of 16, 32 & 64.
