Intel 7260 AC driver 16.10.0 speed/display bug

Just updated to 16.10.0 from 16.6.0.

Before with 16.6.0, I always connected at 886.7Mbps and the "Connection type" in Windows Task Manager WiFi section showed "802.11ac" at all times.

Now with 16.10.0, connection varies from 650Mbps to 886Mbps. But even when it's on 866mbps, "Connection type" always shows "802.11n", it never shows "802.11ac" anymore.

Using 5GHz in both cases a few feet away from router.

Actual real-world speeds appear to be about the same but with more frequent dips in speed with 16.10.0.

I apologize for the inconvenience.

Are the wireless adapter settings configured the same way as they were before?

Hi,

Thanks for the reply.

That's OK - no need to apologize

Yes the wireless adapter settings are configured the same way as before. I've tried with default settings with both drivers, and also both channel widths to Auto with "prefer 5Ghz band", also with both drivers.

I have no issues with 16.6.0 so I'm happy using that now, but I'd appreciate it if you could pass on the message to your driver engineers regarding 16.10.0.

Many thanks and have a good day,

Charles

I have the same problem, with my Windows 8.1 pro 64bit. I have preferred setting of 5ghz for the card and it communicates with my Asus RT-AC68u router but no maximum speed.

I increased it slightly to 702 Mps by disabling Bluetooth in the card settings. I still can't get the 866 Mps speed.

latest driver 16.10.0.

I had 16.6.0 and couldn't see my 5g network on wifi list.

Thank you for sharing your results. By reaching 700 Mbps you are actually getting 802.11ac; let's remember 867 Mbps is a theoretical speed which sometimes cannot be achieved due to ambient noise and interference.

The speed is indeed OK with 16.10.0. The issue is with the "Connection type" that always shows "802.11n", it never shows "802.11ac" anymore.

A simple display bug I assume
