Bad wifi card?

Hey, I just bought a pre built pc from cyberpower and it barely connects to wifi. I just bought a new router with wifi 6 and my speeds tested at over 700mbps. For some reason though, my PC only picks up below 16mbps and drops frequently. I've updated the drivers, done a network reset, deleted and reinstalled the Realtek 8852CE WiFi 6E PCI-E NIC. Im unsure if there's anything else I can do on my end. Is this potentially a bad wifi card on the motherboard? I have yet to purchase an ethernet cable or wifi adapter to test but my other devices, Xbox, TV, phones, MacBook all connect to both 2.4 and 5 ghz just fine but my PC struggles to maintain very slow connection to the 2.4
