Hub 5 high latency and jitter

This issue only started last week. I noticed I couldn't stream BBC radio stations at 320kbps without constant stops and starts. My Hub 5 is in modem mode connected to a TP Link router and I also noticed the router ethernet LED frequently changing from green to orange. I contacted Virginmedia who said they couldn't find any faults using their speed test because the Hub was in modem mode. I ran the Cisco Real Speed test myself and found very high latency and jitter. after unplugging the Hub for a minute or so (a very quick on/off didn't fix the issue) my latency levels were back down to around 20-25ms and I was happy. Until today when the same symptoms appeared. This time I checked the speed directly at the Hub 5 ethernet output so Virginmedia couldn't blame my router and here are a few measurements

I then switched off the Hub for a minute and after restart I measured this

So what is going on. I do not want to have to unplug the Hub every few days and the first warning I get of the issue is my morning alarm streaming Radio 2 fails to go off.

    Hello slartibartfast1,

    Welcome back to the Community, and thanks for taking the time to post. I’m sorry to hear of the issues that you’re experiencing with your connection at the moment. There is an issue with your power levels at the moment and this would need an engineer visit to resolve the problems. I can arrange the appointment from here; however, I would need to confirm a few details via a private message, which I will drop over in a moment. Please look out for the private message, and we can get started.
    Kind Regards,
    Steven_L
