Devmage: added AR5212 section

== This page has been severely messed with ==

Both this and the 11a/b/g/n page state the card works on 802.11a, b, g and n standards. Is one of them wrong?

No. Someone ("MH") turned this page into a a/b/g/n while trying to create a a/b/g/n page by mistake, and caused the current mess because nobody noticed it and more edits were done.

Someone needs to get all the good information in this page into the proper a/b/g/n page, and remove all a/b/g/n information from this page while still keeping the other edits.

I reverted the page back to the last version before the a/b/g/n edits. Doesn't look like there was anything regarding the a/b/g card added after that point. [[User:Pimlottc|Pimlottc]] 05:07, 7 April 2007 (CEST)

== AR5212 Chipset ==

I added a note on the possible chipsets for this particular WLAN card. My system reports that it is using "Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01)" as its WLAN. I have a newer (3 months old) T61, if it helps. If I am misreporting an existing chipset, please revert my change as needed.

Also, this isn't necessarily the proper place to be asking, but has anyone else noticed that this chip causes lock ups? I'm running Ubuntu 7.10, with madwifi as my driver through Envy. Sporadically (usually in periods of heavy use, although that might just be statistics), the system locks up 100% (does not respond to Ctrl-Alt-Bksp, Ctrl-Alt-Del, Ctrl-Alt-F1...), and the caps lock light flashes. A hard restart is the only way to get it going again. Odd, huh?

=== ThinkPad 11a/b/g Wireless LAN Mini Express Adapter ===
This is a WiFi Adapter that is installed in a Mini-PCI Express slot

=== Features ===
* Chipset: Atheros AR5006EX (As printed on card AR5BXB6) or AR5212
* Integrated Mac Processor and Radio Chip: Atheros 5423
* IEEE Standards: 802.11a, 802.11b, 802.11g
* PCI ID: 168c:1014

|}

=== IBM Partnumbers ===
IBM Option PN (US): 40Y7026

=== Linux WiFi driver ===
Use the [[Madwifi]] driver. This driver has support for Atheros rev 0x0024 support since svn revision 2360.

OR (not recommended)

get the driver from http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=MIGR-52527 and use ndiswrapper

=== Hardware switch ===

Some ThinkPads have a hardware switch that must be in the '''on''' position for the radio to work, regardless of driver state:

[[Image:Wireless-switch.png|(ThinkPad R60 radio switch in the ON position)]]

(Note: This may not always be the case. On at least one T60, model 2007-62U with Atheros AR5212, running Ubuntu Edgy with the MadWifi driver, the wireless switch has no effect. Wireless operates with the switch in either position. But there's an [http://article.gmane.org/gmane.linux.acpi.ibm-acpi.devel/137 experimental patch] which adds support of the switch to [[ibm-acpi]].)

=== T60 WiFi LED ===

Problem: The WiFi LED on the T60 isn't enabled by default on bootup.

Solution: As root edit /etc/rc.local by adding the following command at the bottom:

'''echo -n 1 > /proc/sys/dev/wifi0/ledpin;'''

Save your changes, afterwards on every boot up the WiFi LED will be enabled.

Note:This has been verified on a T60 1953-D7U running Fedora 7 Linux, however this
should work on most Laptop-OS configurations.
