Hey, what wireless driver are you using?

Hi, I have the exact same laptop as you and my wireless is working fine, so maybe I would be able to help you out. (I ended up here because I was looking for a driver update). Anyway, I'm not an expert or anything... just thought maybe if I shared my settings with you it might help.

For wireless, I'm using:

Killer Wireless N-1103 Adapter

Atheros AR8151 PCI-E Gigabit Ethernet Controller

I hope that was the information you wanted.

Yes I think it will help. I think I've been trying the right driver on the wrong hardware. I'll find out when I get home in a few hours

Well, if I can be of any further assistance, just let me know. :-)

Looks like I'm still having issues with it. I had 2 unidentified hardware things in my device manager but I looked them up by their hardware ID and they were not the missing Wifi one (both of those are working now). 

The objects I have in network adapters are as follows:

Atheros AR8581 PCI-E Gigabit Ethernet Controller

Bluetooth Device (Personal Area Network)

Bluetooth Device (RFCOMM Protocol TDI)

there are no unidentified devices. I've check that Wifi is enabled in the BIOS. I have pushed the Wifi button at the top right of the laptop(above the keyboard) and it only seems to change the Bluetooth. I have no idea what to try next unless there is a secondary Wifi button I'm not seeing. If anyone has any Ideas I would greatly appreciate it.

It looks like you are missing your actual network adapter. I've attached a print screen image of a portion of my device manager to show you what it looks like. If you need to see anything more, just say. Hope this helps.

Skillet1990,

Rick

My wireless adapter has always worked. Yes, I did have to reinstall the O/S a little while ago because of some malware/viruses. My entire laptop was inoperable at one point.

Are those instructions meant for me Rick? Or for the other person? 'Cause I'm not having any issues with my computer. I was just helping Skillet1990 out because he/she had the exact same system as me.
