Hi, I am Dave, I will help you with this.
The Qualcomm Atheros AR9485 card can only connect to 2.4Ghz networks, it cannot access 5G networks.
If you open the router settings in your web browser, you should be able to set that to dual band 2.4G and 5.0G and then your network card should be able to connect to the router.
Otherwise, you would need to either replace that Qualcomm Atheros AR9485 network card or purchase a small USB WiFi dongle to be able to connect to your new home router.
