I am unable to obtain a wireless connection. When I try to open Dell Wireless Utility, I receive a Wireless Configuration error: Internal configuration is inconsistent. Please restart the machine to resolve the problem. When I reboot the machine, the same problem occurs. Other computers in the same local area can access wireless. I am using a Dell Precision M4300 running Windows XP Professional. The card is a Dell Wireless 1505 Draft 802.11n WLAN Mini-Card. It was working without any problem for the last two years, the last time being a few days ago. Please help me get connected again!
