Re: Need A Guru to have a look at this BQM and Hub Logs If Possible

Downstream power looks a touch too low on your DOCSIS 3.1 downstream channel, the range of power levels across other downstream channels looks too wide to me at 5.6 dBmV (you'll see the uncorrected post-RS errors are correlated with your higher power levels) , and the signal to noise ratio is too low on channel 12, which looks like an RF noise ingress issue.  If all of the coax connections between hub and wall are good, and a restart doesn't sort this out (which I doubt it will) you'll need a technician visit to sort it out.  I'll flag for the forum staff to advise on that.

Re: Need A Guru to have a look at this BQM and Hub Logs If Possible

Hello @bendavid 

 

Welcome back to the forums and thank you for taking the time to post. 

 

Sorry to hear that you have had some issues with your broadband.

 

I have taken a look over everything, It seems as though you have an issues with your downstream power levels.  I have taken the opportunity to book an engineer for you, please check your online account ASAP and let me know that you are happy with the time and date. 

 

Kind regards,

Zak_M
