Service dropouts, speed bumps, time outs, RS Errors

I've been having intermittent Internet over ethernet and WiFi. I have been getting this issue intermittently everyday for around three weeks. I have checked all Coax connections and reseated them which helped a little with the RS errors, rebooted the Hub3, but the underlying problem still persists. anyone have any ideas? All help greatly appreciated.

IGNORE the 23 minute outtage at 01.03am - That was me checking coax connections.

        Hi Carley,

        Thanks for coming back to me.

        I am still experiencing some slow down and a very significant number of pre RS Errors and a number of post RS Errors. 

        I'm running analysis software on a computer connected directly by cable to the HUB 3 and it is showing considerably high latencies (averaging around 35ms but running as high as 180ms with around 4 - 5 % packet drop.

        FYI the Hub3 doesn't handle our WiFi connections - that's handled via an enterprise grade WAP.

        I've a few more things to check out to be sure but I'm veering towards it being an issue with the fibre as the problems have only occurred since Street lighting engineers carried out work on the street and excavated a cable trench directly intersecting the fiber ducts! This of course may be a coincidence.

        As you may have guessed from my moniker I've a reasonable knowledge of networks, and fibre installation as its something I do frequently in my day job  😀 

        Thanks again,

        Jim

    Hi all,

    I've been away for a week so there was nothing in the house connected to the router (apart from a cctv dvr) all other devices were either away with us or switched off as far as I'm aware. On checking the router logs again on our return I'm getting large ammounts of pre and post RS errors and T3 timeouts. would anyone have any ideas?

      Hey there, thank you for reaching out and I am sorry you've been having some connection issues.

      I've taken a look and I can see there was an area outage however this has now ended.

      Has the connection improved since Monday?
