When reading this article, you are experiencing sporadic & recurring connection dropouts or latency spikes on Wireless-N (802.11n) networks. Switching to Wireless-G (802.11g) solves the latency/lag spikes and/or recurring connection dropouts.

Depending on Roaming Sensitivity it may scan more often or less often. In the screenshot above we observe a lag spike of approximately 3 seconds.

This is not the same as Intel PROSet's version. For example: Installing Intel PROSet 16.7.0, will install driver 15.10.5.1 on Windows 8.1, look here for more information)

Solution

Windows 8 only

WARNING: This solution may not work on all wireless cards. Some wireless cards may not be supported on driver version 14.x

This solution is recommended for Windows 8 users at time of writing. Users can always test newer drivers and then revert to the inbox Windows 8 driver.

Revert back to driver branch 14.x, this can be done by uninstalling all Intel drivers when a driver with version 15.x is installed.





Windows 8.1 and Windows 8's second solution (advanced users)

This solution is for advanced users. The advantage of this solution is that you can always use the latest up-to-date driver. A disadvantage is that your wireless card won't scan for other networks when connected, your list of wireless networks may or may not be up to date when connected.
