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

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

[    0.641370] iwlwifi 0000:03:00.0: Detected Intel(R) WiFi Link 5100 AGN,

  Nice to see that it detects the 5100 AGN just like lspci.  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 ?
