I've still not got things working. # iwconfig shows my USB network dongle to have the value: wlx2824ff1a1794 So in /etc/network/interfaces I have:
auto lo iface lo inet loopback allow hotplug eth0 iface inet eth0 dhcp auto wlx2824ff1a1794 iface wlx2824ff1a1794 inet dhcp wpa-driver nl80211 wpa-conf /etc/wpa_supplicant.conf The file /etc/wpa_supplicant.conf has: network={ ssid="ATT680" #psk="..." psk=... } # ifconfig returns: eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet = 192.168.1.203 ... ... wlx28924ff1a17894 flags=4099<UP,BROADCAST,MULTICAST> mtu 1500 inet = 192.168.1.203 ... ... I'm surprised to see both interfaces assigned an IP address even though I'm currently using ethernet wired. One problem is that no mail gets out. Exim main log says: "lookup failed for all hosts in smarthost router: host_find_failed=ignore hosts_all_ignore=defer. No IP address found for host... Is this normal, or does it point to trouble? Another problem is that I can't switch from eth0 to wlx2894ff1a1794. If I do # ifconfig eth0 down and # ifconfig wlx2824ff1a up, I see in # inconfig that eth0 has no stanza and that the wlx2824ffla1794 interface is not RUNNING. Can't ping or browse the web (failure in name resolution). If I restart the network, eth0 is RUNNING, but gets a different address: 168.192.1.212. wlx2824ff1a1974 is also RUNNING, but with old address. I now have no internet access (ping times out), and to recover it I have to bring wlx2824ff1a1794 down.
