Guess I'll throw my name in on this thread too since it seems to be the big one. Samsung Series 9, same wireless card, same symptoms. Right click on wireless icon and troubleshoot in Windows 8 resolves due to problem with gateway connection. Ping -t to gateway shows repeated dropped packets or high latency within 90 minutes routinely, sometimes much less time.
Problem appears to be most evident when transmitting. Packets dropped when clicking links mostly. Occasionally it'll drop 2-4 and come back. If the ping returns "General failure" then she's dead and needs to be disabled/enabled either manually or through the troubleshooter.
I am a service tech of 14 years. I use both Bluetooth and WiDi, and need my wired Ethernet connection as well (corporate VPN requires a wired connection). Disabling one or all of them is not an option and neither is using the non-WiDi Microsoft driver.
None of my other wireless devices exhibit this problem.
Given the number of times we have heard "a fix is on the way", this should be handled in the same way automobile manufacturers handle defects - via a warranty replacement with an automatic warranty extension to cover additional problems.
Instead of saying "we are aware of the problem", what is the next step in the process, Intel?
