I have a Dell latitude D830 with windows XP pro and an internal Intel 4965AGN wireless adapter. I am trying to get it to connect to a D-Link DSL2740B Wireless ADSL router at 108Mbps, but it will only connect at 54. The security is WPA2 with aes as recommended on both the Intel and D-link web sites. D-link formware is current - 2.24 and the Intel drivers are 188.8.131.52. The laptop is currently aboyt 2 metres away from the router - Any ideas anyone?
