As the old saying goes, "use it or lose it"; I used to be able to run wifi on this machine manually (command line) in the past, but now I've completely forgotten how. I've emerged "iw" and "wpa_supplicant". "iw dev" shows phy#0 Interface wlan0 ifindex 3 wdev 0x1 addr 00:26:c6:4a:b4:92 type managed txpower 15.00 dBm Questions... 1) what do I do to scan and get a list of available networks? 2) how do I connect to one of the listed networks (assuming either it's public, or I have the password) ? 3) minor detail... The Google hits I've found all show both DVM and MVM support enabled. Given that dmesg output shows "op_mode iwldvm", can I safely get rid of MVM support ? -- Walter Dnes I don't run "desktop environments"; I run useful applications
