I purchased one of the first Yoga 2 Pro systems and seem to be having problems with my wifi connection.
If the wifi signal is at all weak, it just seems to drop out.
Is there a fix or update I need to apply?
A new wireless (wifi) driver designed to increase wireless performance and stability was provided by Intel and included in the preload on all systems built October 5, 2013 and later. Units built prior to this date have an older driver that should be updated. This addressed some of the early concerns, but additional updates have been made available on the Lenovo support site. Please check your current installed driver version against the latest available on the support site.
Update - Intel has continued to release updated versions of drivers for the 7260 family of Wireless cards, and Lenovo has tested and released signed versions via the Lenovo support site at intervals.
Some additional steps the community has found to be helpful in some cases are:
Modify abiltiy of Windows to limit power to with wifi card to save battery life - this can lead to reduced range and disconnects, especially while running on battery. Here is how to affect this setting. This is a common wifi troubleshooting suggestion in Windows going back to XP - it can be found in multiple discussions in this forum and is not specific to Yoga 2 Pro systems.
Device Manager -> Network adapters -> Intel(R) Wireless-N 7260 -> Properties -> Power Management -> Uncheck “Allow the computer to turn off this device to save power”
Some customers have suggested that some intel software in the preload might be causing a conflict in some cases.
Uninstall “Intel(R) Smart Connect Technology” via the Control Panel...
Reboot to ensure updated driver and settings date effect.
Be sure to check wifi driver version in device manager to confirm it is the latest version you just downloaded.
