Power level check please

Hi,

Can someone please check my power levels.
I have attached the screenshots of Downstream and Upsteam pages

They look pretty bang on from those screenshots. SNR isn't the highest but not below requirements. Are you encountering troubles with your connection?

More like that's what (s)he said if they looked perfect and similar.

On the upstream 1 channel is 64qam and the other is 16qam does it matter as both mine are 16 and was just wondering?

It means that one channel is sufficiently noise free for 64QAM and the other is only operable at 16QAM. If they upgraded upload speeds, in this configuration you'd be limited to the speed attainable on the 16QAM channel. I suspect they won't increase upload speeds till the network as a whole can sustain 64QAM.

The CMTS allocates minislots across both upstreams to a single CPE so it just means that there are fewer minislots available on one channel than the other and that the total upstream bandwidth available to that load balancing group drops from c.54Mb to c.45Mb.

Doesn't restrict to the smallest channel.

A modem requests upstream bandwidth the CMTS will tell it to use a frequency for b minislots at c time and d frequency for e minislots at f time depending on availability of slots on however many channels are in the bonded group.

EDIT: Have a look at https://www.comhem.se/bredband/abonnemang - they sell 50Mb upstream speeds which would be impossible if there were a restriction to the highest bandwidth available on a single channel. The 30Mb-50Mb part covers their backsides in case of congestion.

Connection seems fine, was just making sure it was ok.
