This morning around 9:40, my connection stopped. I have not changed anything in the router in months, so this is unlikely to be a configuration issue.

There is nothing relevant on the quic page, so I thought I'd try my luck here.

I have:
-Rebooted my router (Asus RT-AC87U)
-Rebooted the ONU. The green LED next to the ethernet port is blinking as if data is going through it
-Tried a separate router (Asus RT-AC58U) that has previously worked with quic, and that has the same configuiration.

Both routers give an "Invalid account or password, click the link to modify it." error.
I check the settings, and they are correct (user: quic@quic.nz, password: quic).

Internal network is fine, and pinging other machines on the network works too.

Any thoughts?
