HOW TO MAKE THE WLAN(WIRELESS LAN UP IF IT IS NOT UP IN LINUX)

check the cmd :: ifconfig -a
a) if the wlan is showing then ok other wise you have to follow the following steps :

i) cmd :: depmod
ii) cmd :: modprobe wl12zz_sdio
iii) cmd ::modprobe  wl12xx
now again check the ifconfig -a if wlan0 is showing then ok other wise go to the next step:
GO to cd/lib/modules/3.03.3/Kernel/drivers/net/wore;ess/wl12xx
after that we have to go the a(i) and a(ii) again

If they assign the ip address all these things then ok otherwise we have to assign it manually, for that you have to follwo these steps:

I) ifconfig wlan0 19.68.5.0 netmask 255.255.255.0
II) also we have to give the essid first by following that command

ifconfig wlan0 essid "st"


If wifi is up then u can scan by using the following command:

cmd :: iwlist wlan0 scan

cmd :: iwconfig

**** copy the wli2 thing to Rootfs if it is not present .
copy form 3.03.3 lib module to ---> Rootfs
