[sf-lug] has ubuntu caused me to regress in wifi features?

According to downloadcenter.intel.com (search for drivers and linux):


is good for Intel® Wireless WiFi Link 4965AGN

The download is dated 5/31/2013 which is quite recent


http://wireless.kernel.org/en/users/Drivers/iwlwifi says that

iwlwifi is the wireless driver for Intel's current wireless chips. For 
older chips, ...  iwlegacy (for Intel® PRO/Wireless 3945ABG and Intel® 
Wireless WiFi Link 4965AGN)

and as you point out, has been so since Linux 2.6.3 which is way before 
the date of the Intel download link above.

I'm very confused.

I could try to uninstall the iwlegacy package and install the iwlwifi 
package and see what happens.
