My laptop can't detect my wifi !

[Nikoo]

Recently I changed my windows from win 8 to win 7 . I downloded" Network drivers" via net , and installed it on my laptop but to my surprise it detect other wifis but it cant detect my wifi. I should say when I go to" Network and sharing center " and then click on "Manage wireless networks", I find nothing.

I went to "Device manager" and extract "Network adapters" I find that "Ralink RT5390R 802.11bgn Wi-Fi Aadapter" is installed and when I rigt click on it and hit on "scan for hardware changes" I find that "Enternet Controller","PCI Device","PCI Simple Communication Controller","SM Bus Controller","Universal Serial Bus (USB) controller","Unkown device" aren't successfully installed.

 Thanks before hand for your guide.

@Nikoo

You may need those last drivers installed first.

With the Hardware ID's we can tell what devices and drivers you still need???

The ID will look like this.

PCI\VEN_8086&DEV_422C&CC_0280   or   ACPI\VEN_SMO&DEV_8800

UNKNOWN DEVICE ID:

ACPI\HPQ0004
