Hi there (all again).

I’ve tried a few additional things with no luck, even changed the router with no setting other than those needed to get the internet working.
In all cases 8.8.8.8 and 8.8.4.4 are accessible, all other devices on the home network function perfectly. It’s difficult to take to another site / network as it’s been hard installed but think this is going to be needed.

Using my Ubiquiti router I captured the following. I’d be interested if anyone can spot anything unusual.
I’m still getting http:0 0/0 on the :80 web page fro the device.

I recently upgraded the f/w from a very old version (Thanks Radhoo)…wondering if something related in going from very old>new using early hardware?
