The Linksys card uses the Intersil chipset. You can download the linux drivers from the linux-wlan project Web site. Make sure you download the 11Mbps project! Then follow the tip below. [Thanks to Ren Roderick for this tip!]
The Linux-WLAN project is has Linux drivers for both the Prism and Prism2 based card on their Web site http://www.linux-wlan.com. I’ve been having good luck using this package with the Linksys WPC11 PCCards.
I’ve successfully compiled and had them running under SuSE 6.x and Redhat 5.2 and 6.1. An addition to ‘wlan-ng.conf’ file to include the Linksys id info, a restart of PCMCIA services, and they come up and play wonderfully.
The addition to ‘wlan-ng.conf’ consists of 3 lines:
card “Instant Wireless Network PC CARD Version 01.02” manfid 0x0156, 0x0002
Note that the ‘manfid’ values correspond exactly with the Intersil Prism2 Reference Design Card settings.
