Archer C80 (EU,UK) ipv6 problem. Needs dhcpv6 dynamic or SLAAC option
not sure if i should return the router as it is has a flaw when connecting to certain isps.
I am from the UK and am with Sky FTTP connected directly to an ONT. The problem is with ipv6 configuration. With Sky you need to have the ability to change settings to DHCPv6 and to select either Stateless or slaac under the lan option. Without these it connects but has major issues whereby certain connections/apps/devices don't receive a response from the router. (eg. amazon echo show, phone apps etc).
The only way to remedy this is to toggle the wan connection type to pppoe every 24 hours and leave it connecting/disconnecting with it eventually disabling the whole internet 24 hours later.
Please advise if there will be an update regarding this as I will be returning it back to my local retailer if it is going to remain the same.
