Cable Forum - 200M Intermittent disconnections

I am having intermittent internet disconnections. It started affecting just my Stream box (buffering and multiple error codes eg low bandwidth, Hub not connected to internet), but now this issue has started affecting every device in the house. Sometimes it happens several times per day, sometimes it can go 2-3 weeks without fault. It usually corrects itself after 5-10 minutes. Over the past 18 months I’ve spoken to three different people at VM and been sent two replacement Stream boxes and another wifi pod (I already had one), but still the issue persists.

My Hub and Stream box are both in the lounge, approximately 4 metres apart. I was recently sent the 2nd Wifi Pod, which the Stream box is now connected to via ethernet, but it hasn't hepled. In fact, the issue is now affecting all devices in the house (eg Teams calls disconnecting, mobiles switch to 4g). There doesn’t appear to be an issue with the wifi connection itself, as my mobile can still be connected to wifi manually, but fails to establish an IP address and then drops back to 4g.

I’ve noticed recently that sometimes when the fault occurs, the Hub’s network log has this entry: “ATOM is restarted due to Kernel/oops panic as part of Self Healing Mechanism” From searching online that suggests a possible CPU failure with the Hub, but VM want to send me another Wifi Pod because everytime they run checks on the Hub, everything looks okay apparently (presumably because it’s an intermittent fault). I already have a Hub and a Wifi Pod in my lounge and am still suffering connection issues. Surely adding another Pod in the lounge is overkill and not going to resolve this?

So what are your thoughts? Is this a Hub fault, something interfering with my Wifi, or something else entirely? VM have said that if the suggested new Wifi Pod doesn’t fix it the next step will be to close my account and they will waive early disconnection fee, rather than try to diagnose the fault.
