gig 1 hub 5 post rs errors

[johnnyboy98]

hi 

i'm getting a lot of post rs errors and a couple of things on the logs, I've tightened the coaxial cable going into the hub 5 and checked all the other connections. in a nutshell i would like to get some advice to see if its a noise problem and to see if i need to get an engineer to come out.

Hi @johnnyboy98 

I can see you rebooted your hub 14 hours ago. Are the errors still there or rising?

I can't see any other issues after running some more tests and there's no faults in your area either. 

Thanks

[johnnyboy98]

Hi Thanks for your reply 

I have already rebooted the router before and the errors will come back and then after a week rise.

Hey @johnnyboy98,

Thanks for coming back to us, we would still recommend performing the reboot so that we can monitor your connection from this point and to see if it reoccurs.

Thanks. Joe
