Intermittent signal issues

[asad78611]

I've been having intermittent signal issues for the past couple of days. Is this a known problem in my area and if not can it be escalated

intermittent signals means what - poor wifi or poor internet generally

you look to have a noise issue on the downstream - can you reboot the hub and post the levels again in a few hours

your upstream is on the high side - in limits but only just plus a fair number of T3 errors

if the pre and post rs errors rise after a reboot i would think you need a tech to look at things

ring or wait for VM to get to the thread

Hi there @asad78611, 

welcome to our forums and thanks for your post.

As per the advice given by @-tony- have you now been able to reboot the hub? If so are you able to post the levels again so we can review this further?

Regards

Nathan

Hi,

I did a reboot last night. Haven't noticed any issues so far.
