So I am at a loss right now and looking for any help. I replaced the mini pci-e wifi/bluetooth card in my laptop with an Intel 7260AC about 6 months ago because i was having bluetooth issues with my old card on Windows 10. Since then i countinued to use my great Asus RT-N66U without issue (of course at 802.11N speeds). Yesterday the power button on the Asus RT-N66U gave out, so i decided it was time to upgrade to 802.11AC and went out and bought the top rated 1200AC router (T-LINK Archer C5). Got it all set up only to find that whenever I stressed the connection (downloading large files) the Intel 7260AC would disable itself and would not reenable without a system reboot. Looking in the system logs the Warning that jumps out at me is:
The network interface "Intel(R) Dual Band Wireless-AC 7260" has begun resetting. There will be a momentary disruption in network connectivity while the hardware resets.
Reason: The network driver requested that it be reset.
This network interface has reset 2 time(s) since it was last initialized.
So today i decided to swap out the T-LINK Archer C5 for an Asus RT-AC56U since i have loved the brand and of course the problem continued. I just went into the settings and disabled 802.11AC and i am running without issue in 802.11N now. Does anyone have some angle of attack for me on this one?

Regarding the original adapter, it is recommended to clean uninstall the Intel® Drivers before re-installing the drivers for the original adapter and test your connection to see if the issue remains.
Unfortunately, integration limits our support due to customization that the computer manufacturer may apply.
Thank you for letting us know that this situation has been resolved after rolling back the drivers.
