Slow speeds and disconnects on Gig1 connection - Area 31

Since the last Engineer visit (Oct 17th) following an outage that left me without a connection for 4 days, I've had a lot of issues with my Gig1 connection. These include:

1 - Slow speeds. Since my router was reset I no longer can use SamKnows Realspeed - I just get the following message

Your SamKnows enabled device is offline

Please check your SamKnows enabled device is turned on and connected to the internet.

If I try a speedtest on Ookla (even though I know I won't see Gig1 speeds) the first thing I notice is I have a Virgin Business IP address (which is odd) and my download speed is always <200mbps (Slow), upload speed is between 35 - 50Mbps. Download should be >700Mbps using Ookla, as it was before when I first installed Gig1. This happens even when I reboot the modem, etc.

2 - Disconnects - Strange again, but quite often, and usually about midnight my connection will drop out leaving me in the middle of a Netflix program or movie, and unable to continue watching. I usually reboot the router and it comes back 10 minutes later. Annoying since I am usually watching TV in bed that time.

If I check the Router log there's lots of T3 timeouts like this:

Thu 12/11/2020 04:22:033No Ranging Response received - T3 time-out;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.1;

 

Please could somebody help? I'm unsure of what could be wrong, just that something is NOT like it was when Gig1 worked properly.

My Power levels seem within range, I'm unable to post in this message due to the character limit. I'll try in another message.

Re: Slow speeds and disconnects on Gig1 connection - Area 31

Why do you believe you have a business IP address?

Re: Slow speeds and disconnects on Gig1 connection - Area 31

It states "Virgin Media Business" on Speedtest. Of course, it may not be and I'm probably mistaken (Since it is a class C IP address), I just find that odd since it never stated this before.

What device are you speed testing with?

One of your upstream channels is out of spec:

Re: Slow speeds and disconnects on Gig1 connection - Area 31

Out of Spec? That's interesting. After the previous outage I had no connection, there was an issue with my upstream. The Engineer came, spoke to Network Services and informed me that due to the "noise" from my connection (I'm closest to the cabinet), there was a "block" put on my connection which they "unblocked". Apparently this is normal procedure, albeit most inconvenient for me. Would this have anything to do with this issue? How do I resolve this?
