I have 3 Google Nest Minis connected to my Virgin Hub 4 which keep periodically disappearing, ie. the Google Home app says they aren't connected to wifi and they don't appear in Spotify - this happens on multiple devices, my phone, laptop etc.
When I speak to the Nest mini, it does respond and it is able to connect to the internet and do things.
Initially, I thought this was an issue with the Nest mini devices. But the fact that all 3 were no longer reachable, at the same time, suggests it could be an issue with the Virgin Media Hub 4. Is this a known issue?
