Re: Not getting full downstream speed over ethernet (Leeds, Area 22)

Wait until the area work is complete and check your speeds again.

Re: Not getting full downstream speed over ethernet (Leeds, Area 22)

And if they aren't good check your downstream again - when posted channel 28 wasn't locked, and channel 29 appeared to be completely unintelligible between hub and CMTS, and (if you posted everything) you're missing the all important DOCSIS 3.1 channel.  

I'm a Very Insightful Person, I'm here to share knowledge, I don't work for Virgin Media. Learn more

Hi Dazyellow3,

 

Thanks for posting and sorry for the late reply,

 

How're things since your last post?

 

I've checked the hub settings and everything looks to be within the specifications we would expect.
