Wifi hardware went missing.

Hey guys,

I have a Lenovo G475 running on w7, which was working perfectly fine until yesterday I openned it to work on some sheets then hibernated it (like I usually do) next thing I know is when I open it again my computer wouldnt read the wifi in the notifications area.

I thought it was the external on/off switch. so I turn it on and off a couple times. Didn't work

I read around it may be the power settings, so I switched it from equilibrated to high performance, and reset both power options settings to default. Nothing.

I read that it may have turned itself down via BIOS so I went to boot and through F2 I made sure the WLAN was turned on, yet I turned it off, rebooted and turned it on again. Didn't work.

I have tried re installing the WLAN Adapter drivers from Lenovo site. It didnt do anything.

It appears to me like the hardware went missing. Is there a chance that may be happening? The bluetooth moodle of my laptop is still appearing (and I believe functional) to my laptop bluetooth and wifi share the net cards (at least I think so) so I get to think it cant be the whole net card burnt or broken.

Also there's no trace of the wifi adapter in the device manager to try to re-install the software through there. There's not even a device with conflicts to suppose its the wifi adapter. It's just the Ethernet adapter and the Bluetooth adapter under the net category.

Any help would be appreciated. Since I bought the laptop I'm posting right now exclusively to game (its kind of big and not portable at all) and I'd use my old laptop for university assigments or when I need to carry it around to study I'm in a big need to solve this issue.

Ps. I'm not completely ignorant about computer issues, I thought of openning my laptop to check if the card may have gotten disconnected or something, but decided to ask for help first.

If anyone has knowledge enough to guide me around, I'd be really thankful if I got some walk-through via skype while dismembering my laptop haha

Thanks in advance,
Mashá

Welcome to Major Geeks!

From the problems you are describing, my guess is the internal wi-fi card has gone bad.

The easiest fix is to purchase a nano-size USB wi-fi adapter such as this:

http://www.amazon.com/Netis-Wireles...&qid=1399662099&sr=8-3&keywords=netis+150+usb
(about $13 incl. tax and shipping)

The drivers and software for it are included in the package on a CD. I sell this model at my computer repair shop and have had very good luck with it.

If going this route, I would also "Disable" the defective card in Control Panel.

Hope this helps.
