If you don't, you might have had the same problem i did which was that there was no easy script to initiate the wlan0 device setup. That is to say, if the card was recognized but you still did not get a connection and say that ifconfig showed wlan0 present but with no IP address. In other words, you might see something like this:</P ><P ><P CLASS="LITERALLAYOUT" >text:/home/dude# ifconfig<br> <br> lo Link encap:Local Loopback<br> inet addr:127.0.0.1 Mask:255.0.0.0<br> UP LOOPBACK RUNNING MTU:16436 Metric:1<br> RX packets:14 errors:0 dropped:0 overruns:0 frame:0<br> TX packets:14 errors:0 dropped:0 overruns:0 carrier:0<br> collisions:0 txqueuelen:0<br> RX bytes:700 (700.0 b) TX bytes:700 (700.0 b)<br> <br> wlan0 Link encap:Ethernet HWaddr 00:06:25:A8:AE:64<br> UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1<br> RX packets:1 errors:0 dropped:0 overruns:0 frame:0<br> TX packets:0 errors:0 dropped:0 overruns:0 carrier:0<br> collisions:0 txqueuelen:100<br> RX bytes:46 (46.0 b) TX bytes:0 (0.0 b)<br> Interrupt:3 Base address:0x100<br> </P ></P ><P >As you can see, the interface device, the Wireless pcmcia card, is noted, but there is no <EM >inet addr</EM >.
