i've been trying to get my wlan up and running for days now but nothing so far. hopefully someone out can help me out.

Here's what I'm running:
Slackware 10.2
Linux 2.4.31
ndiswrapper 1.8
Intel(R) PRO/Wireless LAN 2100 3B Mini PCI Adapter

first, dhcpcd wlan0 doesn't assign an ip address.
second, whenever i turn on the physical switch for the wireless it noticibly degrades the performance of my laptop. to the point where text cant be inputed fluently into a console. im not sure where this problem is coming from. possibly ndiswrapper.

any help is greatly appreciated.

thanks

As to slowing down, dmesg might be usefull for diagnose. As to dhcpcd I had same problem. I need to have the card turned on ( special acer_acpi module required on acer laptop ) and a really good signal. Other thing is how is your dhcp server configured. Mine has a list of MAC addresses. Unknown cards won't have IP set.
