If you have emerged wpa_supplicant with USE="qt5" you will have a GUI to launch its client and click on Scan to find and select a desired AP. If not, you can run wpa_cli in a terminal. Something like 'wpa_cli scan' and 'wpa_cli scan_results' should show you what's available. If you run just 'wpa_cli' it will launch an interactive shell from which you can run: > scan > scan_results 'wpa_cli --help' for more subcommands and options. > 2) how do I connect to one of the listed networks (assuming either > it's public, or I have the password) ? With wpa_supplicant's GUI, or with wpa_cli, but the latter is more tedious. Run wpa_cli to get an interactive shell.

Have a look at '/usr/share/doc/ wpa_supplicant-*/wpa_supplicant.conf.bz2' for examples. > 3) minor detail... The Google hits I've found all show both DVM and > MVM support enabled.

I don't know what works with your wireless adaptor, but I tend to experiment initially by building such options as modules and see what is loaded or not and any warnings in dmesg.
