I have a 2 week old laptop with a an 8260 adapter which has caused me nothing but stress from day 1. I suspect this is driver related and hope it will be resolved, but wanted to post here to give some visibility to this as the adapter is still relatively new. I haven't been able to pickup on what causes the issue, at times it seems as though after periods of extended sleep it will happen. I've also noticed it happens more on battery but I've also had it happen while plugged in. The adapter may work fine for several hours, then suddenly starts dropping connectivity even though it has been in the same location all along.
Scenario 1:
- During browsing, my browser will return a DNS error however my wifi connectivity icon shows full bars. Checking the network adapter shows that it has been disabled on its own. Attempting to re-enable it fails as it says enabling then reverts back to disabled. Eventually, after 3-5 minutes connectivity may be restored but it will continue to lose connectivity every 5 minutes or so until I reboot. Once the adapter goes into this "poor reception state", it will drop connectivity regularly until I restart.
Scenario 2:
- Randomly, the WiFi icon will suddenly show an exclamation mark next to the Wifi icon. The adapter also shows disabled and wont re-enable in network settings. In this scenario, wifi does not restore until I reboot the machine.
Some details:
I am using Intel Dual Band AC-8260 adapter running windows 10 on Skylake Architechture.
Using the latest 18.0.33 Drivers
I have tried this workaround, but the behavior still seems to persist again at random times (Power Saving = Maximum Performance).
