firmware from it later. Download it at: http://downloads.openwrt.org/sources/broadcom­wl­4.80.53.0.tar.bz2

or I keep a local copy, just in case: http://ferrari,databa.se/3400/fc8/broadcom­wl­4.80.53.0.tar.bz2

5.Uncompress the driver:

#tar jxf broadcom­wl­4.80.53.0.tar.bz2

6.Extract and install the firmware from the Broadcom driver as root:

#cd broadcom­wl­4.80.53.0/kmod/

#b43­fwcutter ­w /lib/firmware wl_apsta.o

12.2 Get started with WLAN

Now that we have all the pieces we need installed, it is time to check the functionality and get things working.

12.2.1 The manual way

First we do it manually, to make sure we get the results and feedback that we expect. This is to verify the functionality and simplify troubleshooting, if needed.

7. The WLAN interface should show up:

# iwconfig wlan0

 

 

 

 

 

wlan0 IEEE 802.11g

ESSID:""

 

 

 

Mode:Managed

Channel:0

Access Point: Not­Associated

Signal level:0

Noise level:0

8.Turn on the WLAN chip and bring up the interface:

#ip link set wlan0 up

9.OK, now it is time to find out what's in the air:

#iwlist wlan0 scan

wlan0 Scan completed :

10.Choose a network you want to connect to and set the ESSID of your W­LAN interface:

#iwconfig wlan0 essid Perspektiv

11.Your WLAN interface should now be associated with the access point:

# iwconfig wlan0

wlan0 IEEE 802.11g ESSID:"Perspektiv"

Now you are ready to start using your new interface. Most likely your first step will be to request IP setting from an DHCP server (dhclient ­1 wlan0). The next step is probably to permanent your preferences in the file

/etc/sysconfig/network­scripts/ifcfg­wlan0.
