I have a very intermittent connection between my brand new three-port USB Ethernet with micro B and Vodafone router Huawei HHG2500. I suspect it is something with auto-negotiation as the adapter works well on a Netgear GS208 switch. My good old Raspberry Pi 1 Model B onboard Ethernet adapter works fine on the very same Vodafone router. Wondering if there is a way to connect the two Pi’s back to back via USB or serial so that I could troubleshoot auto-negotiation issue somehow.
