The hard drive in this computer went out, and I put in a new one and installed Windows 8.1. Now I am having problems with the wireless on it. (Please see below for specifics.) I have installed the drivers from Dell, but the wireless still does not work. I can turn it on and off from the keyboard (Airplane Mode on or off), but it does not provide me with any options to connect wirelessly. Looking in Device Manager, there is an Unknown Device described as a Network Controller. The device PCI is as follows:
I believe this is the wireless card. The PCI indicates it is an Atheros device. I looked on the Atheros site for a driver, but it redirected me
to Dell. I even ran Dell's driver utility and diagnostics, but it tells me everything is working OK.
The specifics on the computer are as follows:
Model: Inspiron 15-3542
Hard Drive: 320 Gb Western Digital
Processor: Intel Core i3-4030U, 1.9 Ghz.
OS: Windows 8.1, 64 bit
Any help in resolving this problem would be greatly appreciated.
