802.11N will not connect at above 54Mbs


PROBLEM:  Just resolved an issue where a –N card would not conenct at 802.11N connections speeds. It was limited to 802.11G 54 Mbs.

Card was a Dell Wireless 1510 and end user had an 802.11n capable router.

Checked the card settings and 802.11n was not listed as an option in the card properties.  Further troubleshooting revealed that the card connected at 118 Mbs when network was unsecured. 

RESOLUTION:  Both BIOS and Driver were most current and updating them had made no change.  System had been running WPA security, changed security to WPA2 and the issue was resolved.

With this card/router combination it seems WPA will not connect at –N speed, only WPA2
