1 1) the output of "dmesg | grep iwlwifi" is...

3 [ 0.640780] iwlwifi 0000:03:00.0: can't disable ASPM; OS doesn't have ASPM control

13 Nice to see that it detects the 5100 AGN just like lspci. As the old
14 saying goes, "use it or lose it"; I used to be able to run wifi on this
15 machine manually (command line) in the past, but now I've completely
16 forgotten how. I've emerged "iw" and "wpa_supplicant". "iw dev" shows

18 phy#0
19 Interface wlan0
20 ifindex 3
21 wdev 0x1
22 addr 00:26:c6:4a:b4:92
23 type managed
24 txpower 15.00 dBm

26 Questions...
27 1) what do I do to scan and get a list of available networks?
28 2) how do I connect to one of the listed networks (assuming either
29 it's public, or I have the password) ?
30 3) minor detail... The Google hits I've found all show both DVM and
31 MVM support enabled. Given that dmesg output shows "op_mode iwldvm",
32 can I safely get rid of MVM support ?

36 I don't run "desktop environments"; I run useful applications
