There are different reasons why a new adapter may not show in your computer, it could have been a detection issue in the OS, or the hardware; as you mentioned, rebooting is always a good step if the hardware and drivers are properly installed.
We are glad to know that it is working correctly now. Feel free to let us know if you require further assistance.
The only thing I would like to add are the links for the Intel® Dual Band Wireless-AC 7260 Downloads, where you can obtain the latest WiFi and Bluetooth* drivers:
Intel® PROSet/Wireless Software and Drivers for Windows® 10 [19.1.0]
