@Potter002 - I don't have one, but I think there's an option in the PS5 settings to fix the 'frequency' that's being used. Does it help if you explicitly select 5Ghz? I recall reading something round these parts recently where somebody fixed their PS5 problem by disabling IPv6 on the hub too so that might also be worth trying (note that doing this will interrupt your Internet for 5 mins or so and I'd recommend a reboot of the router afterwards to clear any odd behaviour caused by your connected devices getting confused).
