Wifi not working to full potential on ps5

So I don’t really know what subreddit this should be in but I was hoping someone on here could help. So today I bought a PS5 and set it all up. Before this I owned a PS4 Pro where the wifi speeds would be at a steady 250mbps. No when I’m on this ps5 the download speeds of 17mbps. I don’t know how to increase this without using an Ethernet cable and don’t understand why it’s dropped so much when testing the wifi speed itself it gets around 340mbps. Any advice would be greatly appreciated.
