I have a Thinkpad T450s with the dual band wireless AC-7265 driver running Windows 10. I've had no problems connecting in the past but just upgraded my home router to an Apple Airport Extreme. My computer can now see the network but cannot authenticate and join the network. I've seen some talk about this being an issue, what can I do to resolve? This is enormously frustrating. My computer is less than a year old.
Regarding authentication, the Intel® Dual Band Wireless-AC 7265 meets the latest standard requirements. Now a days, the current authentication method most used is the WPA2 + AES. If you are not using this method, please change the configuration on the router and test it.
Also, could you try to temporarely connect without authentication to see what happens? If you have other devices that can connect with issue, please check the type of authetication
