Makes sense, taken them long enough i've been on 16qam upstreams since I moved here 2.5 years ago

Reigate (RH2) has been upgraded to four channels at 64QAM - was only 2 for quite a while

Re: 4 upstream channel bonding - post here
After a 4 hour outage yesterday, some work has been done and my area (Gateshead) now appears to have at least 12 channels available and none are 25MHz.
I also now hit 36Meg up at all times of the day (woohoo)
Nothing else appears to have changed downstream wise.

Re: 4 upstream channel bonding - post here
Ignition said somewhere that they'd be doing away with 25MHz upstream.

Baguley / M32
I'm supposedly on M500 and it's worse than M350 I had last week before they swapped it over :-(

Re: 4 upstream channel bonding - post here
why have you posted your upstream power levels? You are getting full speed on the upstream.

I've now dropped to 4x 32qam not sure what this means but i know 4x64 is better.

Re: 4 upstream channel bonding - post here
It means that there is sufficient noise on the network that it cannot sustain qam64 and has had to drop to qam32. Without looking up the exacts stats you are probably looking at something like a 12.5% drop in throughput so if for example the 4 bonded channels had a maximum throughput of 200mbits, that has now been reduced to 175mbits. Not the end if the world.

I missed in in your earlier posts.
Your frequencies are off-centre apart from channel 4.
They should not micro-change. This wobble will distort your signal.
You should check with your neighbours that they have the same problem. The resolution can lie in the filters of your nearest cabinet or other cabinets in the cascade - or at the CMTS end (less likely).
Hope that helps.

Re: 4 upstream channel bonding - post here
You should be concerned imo. I would report that as a fault and it doesn't self-correct.

So anyone that doesnt have 00000 at the end of their frequencies have a fault? As there are alot of people in this thread like that so it must be common?
