I'm using the pre-release version of artful 17.10 and network manager 1.8.2-1ubuntu2 Much like in Debian Stretch, network-manager is set to use the random mac address feature of network manager, which doesn't allow certain wifi cards/ routers to work together. See Debian bug 836351. I think this feature should be disabled on a live cd, because it isn't fixable during an install and it might cause a user just to give up and not install Ubuntu.
