I’m have my MacBook Airv(OS X 10.9.2 connecting to the Internet via my wireless network which is operated through AirPort Express (5th Generation) 802.11n.)router. I’m trying to get my HP with Windows 7and a 2.40GHz Intel Core i3-370M processor and 802.11 b/g/n Wireless to connect to my wireless network but it says it cannot. The diagnostic program cannot resolve it either. The HP does connect to my neighbors unsecured network and I didn’t have any trouble with my old router/network. I installed Airport Utility on the HP but that didn’t solve the problem either. Does anybody have any solutions?
