Hi
Thank you for the reply.
I've confirmed that it is either the router or the ISP.
I actually phoned the ISP yesterday to see what they say...
he checked what their equipment was reporting and told me that..strangely.. their fiber optics box reported that a SONOS ZP was connected to the box... not my edgerouter.
So he thought there might be something misconfigured in the router..
He said he could see that the edgerouter had been connected before but not anymore..
I have no idea what could cause this.. for the eth0 to somehow be transparent?
Anyone have an idea what I might try to fix this?
