In the stalled state, attempting to access the AC7260 from the Device Manager would often fail, leaving to a non-responsive window. In the stalled state, no more networks are visible (even though many are usually accessible and still functioning with my other devices). At this point, the wireless claims to be connected, but without internet connectivity. When the network card could not recover, it would hang in a 'stalled' state. Sometimes, it would recover on its own after a moment.

Network connectivity would sporadically fail. An excellent example can be found here: AC7260 crashes sporadically since Windows 10 Anniversary update

My symptoms are pretty much identical to other similarly-reported issues with previous updates. My intent is to post the information here, both for others to benefit from, and for Intel to be made aware of the issue, as this will require a driver fix in the long term. I have tracked the issue to a specific Windows update and have found a viable short-term workaround. I am using an AC 7260 card in a Lenovo Y50-70, running Windows 10. I am having issues where my wireless card fails, often into an irrecoverable state. can you provide any assistance with this issue. We have upgraded the driver on 2 affected devices to 18.33 version, this had no affect on the issue. all power saving settings are either set to 'maximum performance' or disabled. This is occurring on multiple 'flavors' of wireless networks - It is not network configuration or appliance specific. when this occurs there are multiple system events in the 500x range for netwinsx32. Rebooting the device restores connectivity and the ability to see other available ssid's. looking at the available SSID's the only one shown was the SSID that had the manually configured profile. All of them reporting 'limited' in the connection status. 2-3 weeks ago we started experiencing random wireless disconnections occurring on multiple devices. the devices all run WES 7 32bit, Windows managed wireless using the 18.20.0.9 driver. We have roughly 600 devices installed around the world on multiple networks, the devices have 7260AC wireless nic installed.
