My internet cuts out 3-4 times per day. It usually requires that the SuperHub be restarted to remedy, it has been happening now for 4 days running. I have tried restarting the hub to default settings however it is still happening.

Currently those levels look sweet.
Upstream power is all that's needed to get an power level of of or around 0dBmV at the CMTS - Depending on how far they are from the street cabinet, these levels can be at around 35dBmV as there is little signal loss between the house and the cab. It's definitely looking much better with all channels on 64QAM.
We're seeing low levels of Pre RS and zero Post RS errors.
I presume you're seeing some upstream noise issues.

Hi Tim,
Thanks for the help! I have noticed the connection has improved after whatever changes were made last Friday, no full-on disconnections since!
I am however noticing lag spikes throughout the day that can also be seen on the broadband quality monitor:
If I were to hazard a guess, I would say that the issue could be from the first engineer visit. He removed attenuators and changed something in the box outside (added a 3-way splitter I believe) - is it possible that could be the cause of the interference?

There's certainly some packet loss on that graph, so at a guess not everything is right certainly.

Hi again,
While there has been an improvement in the internet connection, we are still seeing lag spikes and disconnections. I did receive a message from the forum team asking to confirm details for an engineer visit on Friday, however I haven't received a response since despite chasing it up. Could we please arrange an engineer visit to sort this?

Can you check this?

Hi again,
So we've had another engineer come out. He changed pretty much the entire setup, from components in the box outside to the inlet box and various other parts. It doesn't appear to have helped as I'm still seeing spikes throughout the day and occasional disconnects.
The main thing I noticed since is the very large number of post RS errors on channel 1 & 2 since the change - 663 on channel 1 and 180 on channel 2. I'll post the logs again below:

Hi greigb99
Thanks for coming back to us.
I do see there is maintenance today in your area. Should be resolved soon actually.
Please keep an eye on the connection and report back any issues

It looks like all is well, no disconnects for a few days, ping and packet loss are at acceptable levels!
Thanks for all the help @ravenstar68 and @jbrennand, you guys made it a pretty straight-forward process to get the issues resolved!

Hi,
After a period without issue, the past week I have been getting massive lag spikes and cut-outs once again. Are there any known issues?
