Yesterday I installed Slackware (current) on my computer. I can't cope with the configuration of the wireless network connection. As a result of "iwlist wlan0 scanning" I get a list of some wireless networks, except for mine. When I try to connect to my wireless network, my computer is not getting an IP address from a DHCP server. To connect to my wireless network I'm using firmware downloaded from the slackware-current directory on my mirror.
My wireless network card is: Intel Corporation PRO / Wireless 3945ABG
My access point is: Linksys WAP54G
Has anyone had a similar problem??? What is the solution???

Lets look at a few things. I've got that exact combination of card and router and I know it works.
First off, is your SSID being broadcastby the router? If not, turn on broadcast. Second, make sure that the driver is loaded properly. Have a look in lsmod to make sure iwl3945 is being loaded and have a look in your system log (/var/log/messages, /var/log/syslog and dmesg output) and see if there is any complaining from the card or the driver.
As far as configuring, I've found wicd to be an easy way to deal with wireless in Slackware. You'll find a wicd package in the /extra directory. If you install it, make sure to add your user to the netdev group, otherwise the wicd client doesn't work properly.
I think I know what the problem is, my network is working on channel 12, when I try to switch the card to that channel, I get an error like "Unable to change...". Tomorrow I will try to re-install Slackware to version 13.0. Maybe this will help.

Have you tried to change channel in your wireless router?
It will be easy.
Second, your wireless card might not see your SSID, because router doesn't announce it.
To check this, find other devices with wi-fi and scan.
About the channel number, your wireless card connects not to the number, but to SSID of AP, so channel number has nothing in common with connecting process.
It works, but channel 12 is the only free frequency.
Well, since we all know that nobody actually exists outside of US borders (where channels stop at 11), it turns out you need to add some extra parameters so that when iwl3945 gets loaded it is capable of recognizing channel 12. Try adding this to your modprobe.conf file and either remove and reload iwl3945 or reboot.
