Asus XT8 can't access internet anymore

[Stu59]

I've been running the Asus XT8 without issue for a couple of years. Yesterday it's stopped connecting to the internet. 

Router says it's connected but clearly isn't loading anything.

Using the Sky router and everything works just fine, so I'm using the Asus in AP mode for now to reach everywhere in the household.

Has something changed with the Sky settings that would stop it working?

Another user has reported an issue with a 3rd party router loss of connection today. Their issue ended up being that they were using IPv6 PD authentication to connect to their Sky line, rather than IPv4 DHCP Option 61. IPv6 seemed to have stopped working for them so the connection was lost. Is your Asus router setup to connect via DHCP option 61?

Yeah. DHCP option 61.

Not sure where I go for changing to ip4

@Stu59 by "oprion 61" I assume you are using DHCPv4 Option 61 already which is now failing (ie that is the IP4 method)? If so something odd is happening as that is the default method of authentication for UK lines when used with the user string anything@skydsl (note no dot between sky and dsl the bit from  @is important) and literally any string as the password.

Check the settings as shown in this thread to see if its just a wrong setting.
