You can use the atheros madwifi's ath_pci module (Package: '''madwifi'''). or the newer ath5k module (since kernel 2.6.27). However I used the former since at that time it was the most stable and had fully functional wpa encryption. For the ath5k modlule, please read [https://wiki.archlinux.org/index.php/Wireless_Setup#ath5k this]. Otherwise to load the madwifi driver, type:
+
{{bc|# modprobe ath_pci}}
+
 
+
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 ... ...)
+
 
+
{{Box Note|If despite trying everything the wireless still doesn't work, try a reboot!|}}
+
 
+
Installing these madwifi drivers is common; consult the main [[Wireless Setup]] document for detailed instructions, and the ThinkWiki pages[http://www.thinkwiki.org/wiki/Category:T42] for Thinkpad specific instructions.

This page documents configuration and troubleshooting of the IBM ThinkPad T42.

ACPI

If not already loaded, use modprobe to load the thinkpad_acpi module. See the acpi and laptop articles for more information.

See http://www.thinkwiki.org/wiki/How_to_make_ACPI_work for more ThinkPad specific information.

CPU frequency scaling

See cpufrequtils.

Suspend and hibernate

See Suspend and hibernate.

Wireless

The MiniPCI slot on the T42 usually comes with 1 of 6 wireless cards, 3 by IBM and 3 by Intel.

IBM Cards

  • IBM 11b/g Wireless LAN Mini PCI Adapter
  • IBM 11a/b/g Wireless LAN Mini PCI Adapter
  • IBM 11a/b/g Wireless LAN Mini PCI Adapter II

For the ath5k module, please read the following article: Wireless Setup#ath5k.

If using the ath_pci module, you may need to blacklist the ath5k module.

Intel Cards

See the following: Wireless Setup#ipw2100 and ipw2200.

  • 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)
