Lincoln area issues?

Hi,

My 200M has dropped three times so far, which seems to be caused by an upstream issue. I am in Lincoln North Hykeham near The Forum.

My power levels are below but look to be fine

Re: Lincoln area issues?

Just phoned up on phone and there a message saying they aware of the issue, but it is a complex problem and no eta.

Re: Lincoln area issues?

Your power levels are text book. Hopefully they'll get your area to QAM64 uploads soon.

Re: Lincoln area issues?

2 of the upstreams are normally QAM64, while the other 2 are QAM16.

Re: Lincoln area issues?

i had a lot of drops over the last week or limited service and i don't even get 4 channels ,been like it for a week but speed is still ok,going up to the top tier tomorrow when yodal deliver the router hopefully it will get sorted soon.

Mine become stable around 6pm

Re: Lincoln area issues?

i just checked mine and it does look like they have fixed it :)

looks like i have the 64QAM as well now :)

Re: Lincoln area issues?

looks like you have noise on the upstream the lower frequencies are more prone to noise .
