I have experienced a couple of network drops in the past month or so. This seems to be "new", it hasn't happened before to my knowledge. By "drop" I mean I get "red bars" for wireless signal in the dashboard and Desktop Adapter, and activating or re-activating the SSID does not fix the issue. I have to restart my machine.
As far as I know I am up to date on my Windows critical updates. I was running some optional updates through 18 months ago or so, but have not run optional updates in quite some time after experiencing an update related USB3 failure. Though, unrelated to the wireless adapter per se.
System: Windows 7 Pro x64 SP1
Not sure how I tell driver version, per se. I've got a couple downloaded versions:
FW: 2.11 (or possibly 2.20)
W7: 8.0.0 ?
