High latency and drop outs on streaming and especially gaming

Hi All,

 

Hoping this is not a duplicate post...

I've been a customer for over 10 years starting with 100MB and now on 350MB.

We had an engineer visit just before Christmas and he replaced the hub-3 with a hub-4. We had complained about Internet dropping (streaming and gaming) during the evenings. Log messages of T-3 time outs.

Doing some further research, I've set up the monitor below:https://www.thinkbroadband.com/broadband/monitoring/quality/share/20a5c89e98946b21270dcfd1fd44a1ae50... 

Note there is no one using Internet from 9AM to 3PM today (10/1/2023 Tuesday)

Once I get back I will grab the modem logs and up / down stream outputs and share them on here too.

I have tested  with Sam Knowe4s and the download speed is always over 350MB and even at the laptop is around 300. 

The disconnects are both wired and wireless for streaming and for gaming

Thanks for any help and advice
