# 8. Checking things in case they don't work

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
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
inet addr:192.168.1.104 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:35197 errors:0 dropped:0 overruns:0 frame:0
TX packets:57676 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
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
collisions:0 txqueuelen:0
RX bytes:700 (700.0 b) TX bytes:700 (700.0 b)
wlan0 Link encap:Ethernet HWaddr 00:06:25:A8:AE:64
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:1 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:100
RX bytes:46 (46.0 b) TX bytes:0 (0.0 b)
Interrupt:3 Base address:0x100

As you can see, the interface device, the Wireless pcmcia card, is noted, but there is no 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

which essentially runs a simple DHCP request to set up that card, wlan0, in this case.

You can get the pump by

    apt-get install pump

While I needed to use

    pump -i wlan0

on my laptop, I did not need this when I set up the link-sys wireless WPC11 card on my girlfriend's laptop. She has a Link-Sys WPC11 version 2.5 pcmcia card.
