The MiniPCI slot on the T42 usually comes with 1 of 6 wireless cards, 3 by Intel and 3 by IBM.
- IBM 11b/g Wireless LAN Mini PCI Adapter (use madwifi)
- IBM 11a/b/g Wireless LAN Mini PCI Adapter (use madwifi)
- IBM 11a/b/g Wireless LAN Mini PCI Adapter II (use madwifi)
For atheros madwifi driver, use madwifi throught ath_pci module (Package: madwifi). Eventually you may prefer to use the newer module (since kernel 2.6.27) called ath5k. I'll focus on the old version one once its stability and, at least, fully functional with wpa encryption. To folow up instruction to install ath5k, please read this. To load madwifi driver, type:
If using ath_pci, you may need to blacklist ath5k by adding it to the MODULES= array in /etc/rc.conf, and subsequently prefixing it with a bang (!):
MODULES=(ath_pci !ath5k forcedeth snd_intel8x0 ... ...)
It is pretty standard fare to install these madwifi drivers; consult the main Wireless Setup document for detailed instructions, and if in doubt, always check the ThinkWiki pages. If an Archer has experience with a T42 that uses the Intel PRO wireless card, please feel free to modify this document to inclube information about:
- Intel PRO/Wireless LAN 2100 3B Mini PCI Adapter (use ipw2100)
- Intel PRO/Wireless 2200BG Mini-PCI Adapter (use ipw2200)
- Intel PRO/Wireless 2915ABG Mini-PCI Adapter (use ipw2200)
