Hi,   Yes this is resolved.   I actually had no hardware issue.   To get higher speeds you have to use AES encryption and not TKIP.   I had set most of my wireless devices to use TKIP so when I set the router up that's what I used.    As sooh as I changed the encryption on the router and laptop, rebooted both, I had much higher speeds.    FYI....from a few feet away I connected at 300Meg, in the normal use position I get 120 to 150Meg - the value fluctuates with the data flying around.   Good Luck to you and your situation. Anthony
I have a Dell Vostro 1720 with a Dell 1510 N wireless adapter and I have a N router.    I get an excellant connection, I have checked and the router is set to mixed n/g/b mode.   Why can't the laptop seem to connect above 54 Mbps?   The router is on a lower level mounted on a wall literally 5 feet away from the laptop.  I went to the advanced properties of the wireless card and I changed the ibss mode from 802.11a/b/g/ Auto to 802.11a/b/g/n Auto.    That seemed to make no difference.   Not sure what IBSS 54g Protection Mode is - but that is set to Auto and Afterburner is set to Disabled.    Do I need to change something else to get above 54 Mbps?   
wireless N only connects 54 Mbps
