I just received a new Dell Inspiron 15 3521, 320gb.
I initially activated the product and everything went smoothly; wifi was present unpon activation and all was well. I had recently bought a new 750gb hard drive and decided to replace the existing hard drive with the larger one. I reinstalled Windows 8(64 bit), but I realized that I was unable to detect any wireless connection; the installation process bypassed the Wireless set up screen. When I clicked on the wifi icon, it stated no connection was available. I am only able to get internet access by connecting directly to the router.
I went into device manager and found that there was no wireless adapter under the Network Adapter tab. I went to the dell website to download any available wireless drivers for windows 8. I downloaded and tried all of them, but the problem sill remains unresolved. Under the network adapter tab, there are two Bluetooth adapters, Microsoft Kernel, and Realtek PCIe.
I am stuck, and do not know what to do. I think I have exhausted all of my options, so here I am seeking help. Please help me.
