1. Be sure to type
ifconfig |
You should something like this
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0 .:: expressafrica.net ::.
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
wlan0 Link encap:Ethernet HWaddr 00:06:25:A8:AE:64 .:: biashara.co.ke ::. .:: podcasts.apple.com ::.
inet addr:192.168.1.104 Bcast:192.168.1.255 Mask:255.255.255.0 [Open Source GraphQL]
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 .:: telegra.ph ::.

RX bytes:43386657 (41.3 MiB) TX bytes:2670811 (2.5 MiB)
Interrupt:3 Base address:0x100
The keys point here are that inet addr:has a real IP address, and that Bcast and Netmask are set up such that they are on the same "wave-length" as your Wireless Access Point.
2. 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:
text:/home/dude# ifconfig
lo Link encap:Local Loopback
inet addr:127.0.0.1 Mask:255.0.0.0
UP LOOPBACK RUNNING MTU:16436 Metric:1
RX packets:14 errors:0 dropped:0 overruns:0 frame:0
TX packets:14 errors:0 dropped:0 overruns:0 carrier:0

RX bytes:700 (700.0 b) TX bytes:700 (700.0 b)

Interrupt:3 Base address:0x100
As you can see, the interface device, the Wireless pcmcia card, is noted, but there is no .:: www.arc.agric.za ::. inet addr. The pcmcia software recognized the card, but it has not successfully connected with the Wireless Access Point.
I used the command,pump to send a simple DHCP request to the DHCP server for the device in question. I used
pump -i wlan0 |
You can get the pump by
apt-get install pump |
While I needed to use
pump -i wlan0 |
