My PC is having issues connecting through my USB Wi-Fi network adapter to 2.4GHz Wi-Fi, but it has no issues with connecting to 5GHz.

I looked for an answer for this issue online and tried a few suggested steps, but to no avail. Troubleshooting didn't work.

How can I make it connect on 2.4GHz?

Try locating your WiFi network adapter in Device Manager. Select it and hit "Properties", then go to "Advanced". Choose "Wireless Mode" and change it from "Auto" to "IEEE 802.11b/g/n" (or if you have 2 Wireless Mode Settings, set the a/b/g to "Dual Band 802.11a/b/g" and the n/ac/ax to 802.11n) and hit Apply, then OK.

See if you're able to connect after that.
