Intermittent Broadband Connection (T3)?

[KingLouie1217]

I have been having contact intermittent Broadband connections. Online streaming will stop, online gaming will stop and websites just won't load. The devices state they are connected to the router with a good signal. The wired device is the same.

Initially Virgin sent out a WiFi pod, this didn't work. Several times I have called and done the hard reset on the router and this seems to work for a short time but then the same things happen. Download/upload speeds when tested are normal. I have called Virgin Media who advised to call back in 24 hours if the fault continues. 24 hours later I have recalled and been advised to call back in 48 hours if the problem continues as they will have a technician their side look into it...

From the router network log I can see these errors if anyone is kind enough to help?
I have a Virgin Media 3.0 hub.

I recently posted about some T3 errors I was having, a technician attended and seemed to change something in the box in the street, this didn't work. He then came back and said he was changing a cable outside the house.

I am still having serious latency/lag/disconnection issues, though the T3 error does not appear, there are other errors...

Anyone have any idea?
