Precision 5520 and RJ45

Hi!

Yesterday, i was needed to connect RJ45 cabel to my 5520.

Ive use Dell Adapter- USB-C to Ethernet  and NOTHING!

I google it. And found some intresting issue.

!!!!Ethernet via USB-to-Ethernet Dongle (Optional).

NOTE: : No RJ45 (10/100/1000Base-T, IPv6) provided.!!!!!

So?

I cannt use 5520 with RJ45 (wan or lan)?

Nice!
