a bit of a mystery here ... after wireless has worked just fine on
this laptop for months on end, i show up at a friend's place after
work, fire up the laptop, expect to connect to his wireless same as
usual and ... nothing.
check the network settings thru network manager and not only is
wireless not active, the setting is greyed out so i can't even select
it to activate it. how odd.
"ifconfig -a" shows a wlan0 interface, but it's not up. then
there's iwconfig:
wlan0 IEEE 802.11bg Mode:Managed Access Point: Not-Associated
Tx-Power=off
Retry long limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
If "ifconfig" without the -a doesn't show the interface then...
if i try to scan with that interface:
# iwlist wlan0 scan
wlan0 Interface doesn't support scanning : Network is down
Is not unusual. The same thing happens here.
But, all I have to do is us the NM applet and check "Enable Wireless".
And all is back to normal.
#
and
# ifconfig wlan0 up
SIOCSIFFLAGS: Unknown error 132

time to start googling, of course, but all of this came on suddenly
and for no apparent reason. thoughts?
My minor thoughts are above. My system is a desktop with a wireless
embedded on the motherboard that I don't normally use.
I suppose the question is...what is your HW and is the driver loaded?
