Is my Ralink RT5390 802.11 b/g/n 2.4ghz or 5ghz?

I'm looking to improve my laptops wifi reception so I can stream baseball games off of MLB TV without the constant buffering. The router and modem which I'm piggy backing off all the way in the front of the house is 2.4 GHz and 5 GHz compatible, but after looking through some related questions and answers on my specific laptops specs, I'm pretty sure I only have 2.4 GHz. I have an HP Pavilion DV 7-6b56nr notebook PC with a Ralink RT5390 802.11 b/g/n. If I buy a USB wireless dual band wifi adapter (like an ASUS USB-AC68 AC1900 Dual-band USB 3.0 WiFi Adapter) which accepts both 2.4 GHz and 5 GHz, will that supersede my internal cards specifications? Meaning, if my internal Ralink is only 2.4 GHz, will the wifi adapter suddenly make my laptop accept 5 GHz? Or can I, and should I, even consider upgrading my Ralink interior card to 5 GHz? Will that make a bigger difference than an external USB Wireless Dual-band adapter? Thank you.

Hi:

Your notebook's Ralink RT5390 Wi-Fi adapter is a single band (2.4 GHz only) Wi-Fi adapter.

Yes, if you buy a dual band Wi-Fi adapter, it will work fine.

You just need to disconnect the Ralink Wi-Fi adapter from your wireless network and connect to your network using the USB Wi-Fi adapter.

Make sure you set the USB Wi-Fi adapter to automatically connect to your network.

How, please?

Thanks.
