Ok, so I picked up 2 of these Antsig AP581 USB adapters as they were listed as working under the wiki for my IPFire project box as it only has one standard gig e adapter.
I’ve found that when using them, either as the green or red interface int doesnt pass on/receive DCHP requests, and gets an APIPA address.
I can manually configure the port and it does connect with no problems, but i do need it to work for DHCP as that is how my ISP provides my static IP.
I’ve tried it with various computers and it exhibits the same issue across the board. It is running through a USB C to USB A adapter which should have no impact (and I have tested with just USB C connection)
I’ve begun to think perhaps the cable type is actually causing it? Maybe it needs to be a crossover cable vs a straight through.
Anyone else seen this, and have any suggestions
