--- Comment #1 from Matti Viljanen <matti.vilja...@kapsi.fi> --- It turns out all I had to do was the following: Go to System Settings - Connections - (the integrated Ethernet device) - Wired - Restrict to device, and from there select the MAC address of the said device. Now when I plug in the other USB device that acts as a Ethernet device, its interface now gets an IP address from the device's DHCP server. FWIW, I flashed Manjaro Gnome, and it allows multiple wired DHCP connections OOTB, as does Windows (the last time I used Windows 10 in such environment a few years back). So, technically the bug is solved, but to me this still completely counter-intuitive, as only one active connection isn't something that I expect from a desktop system (although my technical background gives me a bias on this). This might be a usability/documentation issue instead -- I'll let others be the judge of that and flip the bug status accordingly. -- You are receiving this mail because: You are watching all bug changes.
