Wireless is slow using the iwlagn driver and the Intel Pro/Wireless 4965 AG. When I connect a LAN cable to the ethernet jack my speeds pickup tremendously. I transferred 125 megabytes over lan cable in 3 minutes within my local network. The same task took 1 hour and 30 minutes using this wireless driver.
Clearly iwlagn does not support full wireless speeds on the Intel Pro/Wireless 4965 AG.
