I was checking the WiFi connection on my Acer Laptop (Travelmate 4280) in order to help “nitt” and some funny/strange things are happening:
(the Acer WiFi has a prowifi3945 -Intel- chipset)
1- after booting, checking the Deskbar icon for network I can see all netcards listed but no WiFi network name.
2- checking the settings of the prowifi3945 in “Open network preferences…” in the Deskbar network icon the prowifi3945 is listed as if it were a LAN-Ethernet card only (not WLAN-WiFi)
3- launching “wpa_supplicant” from a terminal I got no messages but the cursor goes new-line (then I do Ctrl-C to get rid of the “pending” command).
4- after a while of the command 3- above and going back to 2- I see finally the prowifi3945 listed as WiFi along with other settings like Network: name and Mode:
5- doing apply on the screen of 4- I get a screen for Open/WEP/WPA/WPA2 selection and password input.
6- I can go no further because I don’t know the password (this is NOT my network) and I do Cancel.
7- However if from a terminal I enter “ifconfig /dev/net/prowifi3945/0 join network-name” OR the same but only with “join” (no network-name) I got this message:
ifconfig: “/dev/net/prowifi3945/0” is not a WLAN device!
which sounds quite strange indeed because I know it is a WLAN device and almost connected to a WiFi network (missing password…)
What happens?! (the graphical part seems to work better than the CLI commands).
Running wpa_supplicant from a terminal is also quite strange (it should be launched automatically from somewhere else) - what am I doing wrong?!
PS.: the broadcom570x (/dev/net/broadcom570x/0) is always seen/listed as a LAN card (NOT WLAN-WIFI) under Open network preferences… (as in 2- above)
Just some findings…and I hope this can be useful.
