5Ghz Wi-Fi won't work

Hello, just got my new Manta today. I was able to connect to the 2G network just fine, but won't work with 5G network. It won't find it and when I try to add manually it does not connect.

My router is an Asus RT-AX3000, it's using standard WPA 2 Personal security. Does this device only support 2G or is there something else going on?

I'm on version 3.23.32, and sitting right next to the router. The only post I found about this didn't have much info.

Thanks.
