If you already instaled 8.1 then I think it takes it out when it installs the new 8.1. Jst make sure you download and install the wireless drivers for 8.1 if you haven't already done so. Just go to Lenovo.com and download the driver form there. Let me know if this helps.

I cannot install an 8.1 driver for this because Lenovo and Windows do not appear to have a download for this wireless card. They claim the correct driver automatically loads with the Windows 8.1 install. The G500s do not come with the Broadcom card anymore, they come with an Intel Centrio(R) Wireless N-135 card. I installed the Windows 8 driver last night and it seemed to solve the issue. However upon waking up and bringing the computer out of sleep mode, the wireless connection is far worse. It is dropping the connection every 1-2 seconds, goes limited and connected like crazy. This is pretty much unusable right now.

I have 2 of these machines "Lenovo G500 59399747 Notebook Core i3 4GB 500GB DOS" . I have tried it with Win8, Win7, Unbuntu and CentOS. In all cases the same issue.
The System see´s all of the WLAN in the area but will not connect or directly disconnect. I have tried that with a simple USB WLAN adapter and it is working fine. Seems an issue with the N-135 card.
I have send one of the G500 to Lenovo to have a check at the weekend. Expect that they will change the Adapter.
I will keep you updated what they have done to fix.

Thanks Adabar, look forward to hearing what they did to fix or if they even can.
The Windows 8 driver from the Lenovo support site for Intel has a date of 6/13/2013 and a version number of 22.214.171.124(WHQL). The driver that is currently showing in my Device Manager after performing Lenovo suggestions of uninstalling and installing driver in compatability mode is a Microsoft driver from 6/25/2013 with version 15.10.12.
Not sure why the versions numbers and dates are off, I downloaded the Windows 8 driver from the Lenovo site.

One other thing I forgot to mention is....if you go to the Intel site for the Intel Centrino N-135, they list the latest Windows 8* driver version as 3.1.1309 and have a date of 10/21/13. Not sure why Windows and Lenovo would both think the latest version is from June and have such a dramatically different version number.

As I mentioned earlier lenovo site does not have the correct driver. It tells you the driver for 8.1 is automatically installed with windows 8.1 upgrade. There is a windows 8 driver but its date and version number do not match the actual Intel driver site for this card.

My first is back from Lenovo. They have replaced the Intel with a new Intel N135 card and it´s working now-
. The second is just on the way to change the card.
My was build Sept. 29th 2013. You can check on the label behind the battery.
Maybe it´s a problem with this series.
