Looking at your "Intel Dual Band Wireless-AC 7265 - network adapter / Mfg.Part: N4G85AT" and was wondering if this would work on my daughter's "Dell OptiPlex 3040 desktop? (Service Tag: 2XV0QD2 ) Wanting to move it to a room with no wired connection

The 7265 is a module that is getting pretty long in the tooth (though I still have a half dozen in use). By Amazon pricing, this module costs US$15. For just a few dollars more (US$22), you can purchase Intel's latest AX200 module, which future-proofs you with support for Wireless-AX, WiFi 6 and Bluetooth 5 (but fully backwards-compatible with Wireless-AC, Wireless-N, WiFi 5 and Bluetooth 4).

Just a thought,
