I am running Windows 7 x64 Home Premium, recently I had a hard drive failure and installed a new one. The O/S installation went well, but I had no internet or network connection. My system has to NICs. One is hardwire the other the wireless, which is the subject matter. The system detects the Realtek NIC, but has a caution symbol but the other network controller, which is the wireless. I tried updating the driver
and I get "Windows was unable to install your Network Controller". It could not find the software for your device. I went to the Dell site downloaded the drivers
I disabled the Realtek and tried again, same message. I uninstalled the drivers for both NICs, rebooted, it detected the Realtek, the other still has the caution symbol. The wireless card has the green light on but the other is not blinking. I opened up the case removed the card and placed it back, same results. While the system was running I removed the card and the put it back and the system didn't respond at all. I am using my laptop for this forum, It has windows 7 x64 Ultimate Edition, and it connects fine, so there is no issue with the router. There is another laptop and game system using the network with no problem. Is my card defective?
