Intel 7260-ac - Driver (Bookmark this one)

I have a ticket open with Intel about random disconnects. I have a few hundred Lenovos with the 7260ac adapter. Randomly we’re seeing clients sending a dauth for what appears to be no reason. 


When asked if they publish release notes on their drivers they responded NO, not public facing.. Which I knew from past experince. However, the SE I spoke with provided me the release notes for the lastest driver, 


I wanted to share with the group.  I also shared my frustration with navigating around Intel site for their cards, drivers and documentation. They provided a great link which is bookmark worthy. It lists all their wifi nics, documents and drivers. Also does a comparison.

Thanks George.


Intel absolutely drives me nuts not publishing the release notes.  It's very difficult to recommend driver updates when a list of known issues is not published so you never know what you're getting into.

For this I have also seen that by default the HT mode is set to VHT. Once I have changed this to be 'Auto' in the wireless adaptor settings on the client the connection is stabilised.
