7260AC random disconnects - limited connectivity displayed - no other wireless networks visible

ktrim · ‎06-21-2018

we have roughly 600 devices installed around the world on multiple networks, the devices have 7260AC wireless nic installed. (7260HMW). the devices all run WES 7 32bit, Windows managed wireless using the 18.20.0.9 driver. 2-3 weeks ago we started experiencing random wireless disconnections occurring on multiple devices. All of them reporting "limited" in the connection status. looking at the available SSID's the only one shown was the SSID that had the manually configured profile. Rebooting the device restores connectivity and the ability to see other available ssid's. when this occurs there are multiple system events in the 500x range for netwinsx32. This is occurring on multiple "flavors" of wireless networks - It is not network configuration or appliance specific. all power saving settings are either set to "maximum performance" or disabled. We have upgraded the driver on 2 affected devices to 18.33 version, this had no affect on the issue. can you provide any assistance with this issue.

Hi ktrim,

We understand that you're having an issue where multiple devices running Intel® Dual Band Wireless-AC 7260 adapters are experiencing random disconnects that result in limited connectivity, we'll be glad to assist on this issue.

We have a couple of recommendations we can provide you in order to try solving the scenario, which are the following:

a) Perform a https://www.intel.com/content/www/us/en/support/articles/000022173/network-and-i-o/wireless-networking.html clean uninstall of the adapter drivers.

b) After this, reinstall the latest driver package https://downloadcenter.intel.com/download/27851/Wireless-Intel-PROSet-Wireless-Software-and-Drivers-for-Windows-7- 20.60.0 and retest the devices.

c) In case the issue persists, send us a copy of the log file generated by our https://downloadcenter.intel.com/download/25293 Intel® System Support Utility and attach it on your next reply.
