Lately I got (used) an APC Back UPS Pro 1000 and Back UPS NS 1080. I got an

though looks just like the Pro.

I can't speak for the rest of your problem...

but just for accuracy, the "ethernet" connector isn't an ethernet connector if 
it's being used for USB.

That connector is correctly ID'd as 8pin modular.

They're commonly called RJ45, but that too is a misnomer since RJ45 is a 
telephone specification (RJ=registered jack) that not only calls out the type 
of connector but also the signals on them.

Having a history in Telco, it's one of those things that always made me wince when folks 
like Cisco would call an ethernet jack an "RJ45" when Cisco is so anal about so 
many other things in the biz. LoL...

So I thought I would just share for fun...

Cheers and happy holidays!
