Mine went from 3x 64qam to 4x 16qam, according to Virgin this is normal...

Re: 4 upstream channel bonding - post here
 

Mine went from 2x64 which i had only had a few weeks to 4x16 and i even had a repull for a separate power level issue and even that didn't bump them up to 4x64.

But the repull still fixed my power levels on the V6 and i still get max download speed 24/7.

i dont think he meant you in particular, but in general if it "works" there is no fault" vm attitude

Re: 4 upstream channel bonding - post here
 

Internet just went off for 20mins and i now have 4x 64qam upstreams in CB24 area, this is significant as i have never had this before and have mostly been on 16qam, hopefully they upgraded something and the change will stick.

Re: 4 upstream channel bonding - post here
 

For bonded channels here.

Re: 4 upstream channel bonding - post here
 

Still 4x 16 here, really struggling with the new 35 upload, suspect the 2 are related!

Re: 4 upstream channel bonding - post here
 

What's happening to my spelling? I got the 35Mb upgrade before I noticed the four bonded upstream channels.

Now on V.VIP and doing very nicely here in Coventry.

So the internet just went off for 30mins, this was preplanned as they sent me a letter.

The changes i can see are Downstream power level has gone from a high of 6.4 to 3.9 and the upstream from 38 to 40.

Upstream frequencies have changed, any idea what improvement this will give?

Old
1 25799803 3.75 5120 64 qam 4
2 46200018 3.825 5120 64 qam 1
3 39400045 3.825 5120 64 qam 2
4 32600085 3.8 5120 64 qam 3

New
1 25800000 3.975 5120 64 qam 4
2 39400000 4.025 5120 64 qam 2
3 46200000 4.025 5120 64 qam 1
4 32600000 4 5120 64 qam 3

Re: 4 upstream channel bonding - post here
 

Everything is the same - just the channel order is different.

Except that the last two digits are different. Whether or not the old signal being so slightly off centre would give you a bad experience - I can't be sure. Instinct tells me that any degree of centre can give trouble.

Re: 4 upstream channel bonding - post here
 

Out of curiosity i just checked mine and while i'm still on 4 upstreams, they're all 64QAM rather than the 16 they used to be.

Maybe a coincidence but i'm also able to consistently see 35meg up now as well :)

EDIT: Also looking at downstream channel IDs my area now has at least 30 available so some kind of work as occurred recently

Re: 4 upstream channel bonding - post here
 

By moving from 16QAM to 64QAM, the packing density on the upstream has increased by 50%. That means they've cured the noise problems.

Re: 4 upstream channel bonding - post here
 

Now the frequencies have changed again, is it normal for them to move about?

1 25800050 3.975 5120 64 qam 4
2 39399885 4.025 5120 64 qam 2
3 46199975 4.025 5120 64 qam 1
4 32600000 4.025 5120 64 qam 3

Re: 4 upstream channel bonding - post here
 

Not normal at all.

The frequencies are going off centre, but it seems that your Hub 3 is able to tune in OK. If there are no timeouts and upstream speed is fine, then you'll be leaving it to the network team to resolve once their monitoring tools alert them.

Re: 4 upstream channel bonding - post here
 

Hitting 'refresh data' isn't changing them and the readings from yesterday were taken straight after their maintenance work.

Whats the best speed test site that gives all the info like buffer bloat etc as i find the below has issues measuring the upstream and goes far fast than it should then it trips out?
