I just bought a new 5-port NetGear ProSAFE FS105 Ethernet switch. It works just fine with my Mac Mini, but it does NOT work with my Macbook Air through the j5 Create USB 3.0-to-USB adaptor I've always used for that purpose in the past. I get "Status: Connected" with the error message "AX88179 USB 3.0 to Gigabit Ethernet has a self-assigned IP address and will not be able to connect to the Internet." Tried my old Belkin USB adaptor and got a similar message. Tried different ports on the switch; same result. So it seems like the switch will ONLY communicate directly to an Ethernet port and won't accept any kind of adaptor? This could be a problem, since I don't have wireless internet at home.... Network is set to connect using DHCP with passive FTP mode. How can I figure this out?
