Chromecast HD 'No Internet' message and IPv6

[Sgr99]

I have a wierd problem with my Chromecast HD connecting to an EE router via an EE extender. The Chromecast keeps giving a notification that it's lost its internet connection when it hasn't (the Chromecast very briefly says 'No Internet' in the status area then the notfication pops up). This message pops up every couple of minutes or so and ruins anything I'm watching but mainky in YouTube. Google doesn't want to know saying it's an EE problem as it doesn't happen when I connect via my phone's mobile hotspot (connected to the same wifi) or if I turn the extender off and connect to the main router (very poor signal as oppsoed to excellent with the extender on). When I look at the device in the router Hub Manager My Network, the device has hundreds of IpV6 GUAs which doesn't happen with other devices....see pics. Anyone come across and resolved this?

The one that it is presenting to the hub - although that would also be a good test, to confirm whether turning off randomisation fixes the issue (e.g. if the hub is somehow making the Chromecast think it's changing network, causing it to generate a new Mac address - this would explain the multiple IPs).

Hello

I've sent through some info re the error messages to the email you shared. The random Mac address and IPv6 settings change had no effect unfortunately.

Let's see where this leads.
