[ubuntu-in] How to test if the wifi hardware is working

[ramnarayan.k at gmail.com]

Hi

Yet another hardware /software problem

The Lenovo t60 i use has Intel Corporation PRO/Wireless 3945ABG Network
Connection

however i am not sure if something has gone wrong with the software and
/ or device because some of the diagnostic commands / software i use to
keep a track of wifi networks seems to not work

the CLI command i use is
~$ watch iwlist wlan0 scan

the software i use is swscanner

so is there anyway i can diagnose if my hardware has gone faulty ??

regards
ram
