Thanks for replying. I have around 30 connected devices but most are IoT devices, such as smart speakers, taking up very little bandwidth. Support wasn’t able to tell me if it there was a single (or group of) devices causing the issue. My WiFi config (with the Superpods) is as per the recommendations.
The access for the Plume Homepass app is specifically for those customers. VM customers don't have a subscription with them as your pods are supplied directly through us.
Looking at your Hub, everything is looking good from this side so the only thing we can give you is our WiFi link to optimise things. I can see you already have the maximum number of pods so if you are still having an issue with WiFi connection then the only other thing we can advise is to go down the route of a third party router or mesh system.
I know this wouldn't be the news you're hoping for but everything is looking fine from this end I'm afraid so nothing more we can do.
