Hi there! I have just recieved my new PC from Cyber power systems, I have installed all the drivers that came with the PC, but yet my wireless card doesnt work, I have bought the PCI-E Wireless 802.11n 300Mbps Network Interface Card and installed all drivers, downloaded several from various websites, and yet still in device manager it says Network Controller has a ! mark and when i go to show full map on the internet troubleshoot, it tells me the device isnt plugged in, So heres the problem, the wireless card either wasnt attached to the motherboard correctly (or where ever its attached) Or i have not got the right Drivers :L The MotherBoard i have is a Asus
