I've got an AR5418 chip in a T60 laptop connecting to a Dlink DIR-655
Hardware version A2, Firmware version 1.11. As I understand it, these both
use the AR5008 series chip sets.
Using the driver in svn3401, I am consistenly able to get ~2MB/s up and
down, however going to svn3545 and higher (including the latest svn3766)
this is cut down to about 600KB/s. My tests consist of using scp to
transfer a single large tar file to and from a machine connected to one of
the wired Ethernet ports on the router. I'm connecting using WPA2-Personal
with CCMP encryption.
Please let me know if there is any additional debugging I should do.
This is my card according to lspci:
