Hi! All, Solved the wpa_supplicant "No Such Device" problem on my system. Change "allow-hotplug" to "auto" of wireless device stanza in /etc/network/interfaces. But now wpa_supplicant fails to authenticate. However, wireless dongle (Rosewill RNX-N180UBEv3) will connect with security turned off on router and interfaces appropriately configured.
Checked dongle on a friends older (4 or 5 years?) notebook running Windows 10. Entered passphrase in network manager, and it connected and worked just fine. Router works, too. My 5 or 6 year old Nexus 4 LG 960 smartphone works with it, the Roku device on the TV, too; and so does a 10 year old Kobo eBook Reader. Thought it might be related to my atypical Stretch install on this old (4 to 12 years, depending on the part) under-the-desk box -- minimal install, window manager Openbox only, sysvinit, no network manager at all. Had never intended it to be wireless capable, but have installed all the appropriate wireless software. So, I pulled out a Stretch Live USB thumb drive (LXDE GUI, systemd and all) and booted it up. After installing the non-free Realtek drivers, brought DOWN the wired ethernet, unplugged it, and inserted wireless dongle. It got recognized and proper driver loaded, but I had to bring it UP manually. Using wicd, I configured the proper passphrase, etc. and clicked CONNECT. It failed to authenticate, too! So, anyone got any ideas what the problem might be or a fix? My research has led to nothing that worked. And I'd like to get rid of the 50' ethernet cable running down the hall. ;) Thanks B
