Hi,
I have an Intel Nuc Windows 10 64-bit computer with Intel Dual Band Wireless-AC 8260 adapter (driver version 20.70.0.5, newest at the time of asking).
Every now and then the computer loses the connection to my 5 GHz wireless network. It happens most frequently when re-starting or waking up from hibernation, but it may happen at any time. After the connection has been lost the wireless network can't be found in the list of available networks. The 2.4 GHz network can still be found though. One, or a few restarts solves the issue temporarily.
I have tried with two different routers and have the same problem regardless. No other computers or devices on the network has these problems. This incluldes other Windows 10 64-bit computers.
Thankful for help.
Erik Henningsson

Hello Diego,
Thank you for the help!
I have followed your guide and am now finding out if it works. There has been one week without problems so far. However, even before there were sometimes problem free weeks so I can't yet decide if the the complete driver re-installation worked.
I will let you know if I experience the problems again or in a few weeks if I haven't experienced any problems.
Best Regards
/Erik

Hello oss_erik,
Thank you for your keeping us posted, I understand that then issue remains and that you have tested multiple routers and machines.
For testing purposes please go ahead and try our https://www.intel.com/content/www/us/en/support/articles/000024678/network-and-i-o/wireless-networking.html Recommended Settings for 802.11ac Connectivity in both routers.
I hope to hear from you soon, please let us know the outcome.

Hi Diego,
I checked the settings you linked. The settings in the problematic computer were already the recommended ones. The same is true for the router I am currently using. With two exceptions:
- Channel width is set to 80 MHz and it doesn't seem to be an option to set it to allow all channel widths.
- Wireless mode is set to 11ac and it doesn't seem to be an option to set it to allow all all wireless modes.
Are these two options important for the current issues? The other router I borrowed from a friend and it is quite a hassle to get it again. Is it really necesary?
To summarize. The link you sent didn't result in any changes. How should we move forward?
Best Regards
/Erik
