We have been dealing with some Lenovo Yoga 13 ultrabooks recently and the wireless cards keep disconnecting and then refuse to reconnect. After reading on the Lenovo forums, this appears to be widespread on these models. Below are fixes we have compiled from different people that will fix the issue. We now have the Yoga 13 working properly.
#1 – Disable Realtek RTL8723A Wireless Suspend
Bring up the device manager by searching “device manager” from the charms menu under settings.
Click on network adapters in the device manager.
Right click on “Realtek RTL8723A wireless …” under network adapters. Click on properties.
In the properties box click on the advanced pane.
Inside the advanced pane set the following values to these parameters:
Selective Suspend: Disabled
#2 – Change Suspend Timeout
Selective suspend timeout: 60
WiFi config: WiFi
Click OK to save settings.
#3 – Disable Power Saving on Nic
Right click on the network adapter, go to properties.
Click on Configure.
Go to the Power Management tab and uncheck “Allow the computer to turn off this device to save power.”
#4 – Turn off password protected sharing
Go to Network and Sharing Center and click on “Change Advanced sharing settings.”
Under “All Networks” select “Turn off password protected sharing.”
