Hi All,
To update my post, I actually resolved this issue.
At the time of writing this comment I am on BIOS v1.0.17 but in reality the BIOS version did not make a difference.
This issue for me with the Intel AC8260 WiFi Card is 2 fold.
1. In the Power Mangement tab of the Wireless Adapter properties in Device Manager Turn off allowing the computer to put the device to sleep to save power.
2. In Power options (Classic Control Panel for those with the new Windows 10 update) hit 'Choose what the power buttons do' and then 'Change Settings that are currently Unavailable' and then uncheck 'Turn on fast-startup'
Reboot the system and I have a working adapter each and every time. It works whether I Hibernate, Sleep, Power Off or Restart the laptop.
The concerning thing for me though before the above solution is:
Killer Wireless 1535 card powers up with WiFi Radio each time but no Bluetooth Radio.
Intel Wireless AC8260 Powers up with Bluetooth each time but no WiFi Radio.
Suggestions would be that when Windows 10 uses Fast Start or Puts the Wireless Adapter in a low power state the Wireless adapter never recovers from this power state and a full cold start has to be performed.
It might be that the stock Intel AC3165 is only a 1x1 card at 433.3Mbps and does not have this issue, where as the other 2 are 2x2 cards @ 866.7Mbps with more modern architecture. Never the less, the motherboard in the Acer Aspire R3-131T is more modern than any of the cards so should support the card itself.
It's definitely an issue with power states it seems and turning off power management and windows fast start has resolved it. Fast Start is redundant for an SSD powered laptop anyway. I have no performance loss at all from a cold boot.
Cheers
Vince
