How to set router for 5ghz

Hello. Just got a new Asus router rt-ax88u which is wifi 6. Son had a new pc for Christmas which is for gaming mostly, which also uses wifi 6.

I read somewhere that it's an idea to set the 5ghz channel purely for the gaming pc. But am not sure of the best way to do this on this router.

Both 2.4 ghz and 5 ghz each have 3 guest networks available on the Asus router.

On initial set up I have a main SSID for both 2.4 and 5GHz and have then set up a 5ghz guest network with WPA2 Personal security - for son to log into on the gaming PC and a 2.4ghz guest network for smart devices.

However it has occurred to me that this doesn't mean the gaming PC has sole use of 5ghz. Would it be better to set two separate SSIDs for 2.4 and 5ghz and just use the 5ghz for the gaming pc (as opposed to a guest network on 5 ghz?)

Other devices are quite basic - phones and a laptop just for surfing etc.

Thanks - the router has a "smart setting" which is on by default for the main sSid which I don't fully understand but assume it switches all devices between 2.4 and 5ghz as it thinks best. And on computers it does not show two separate networks as before -- just the one SSID. The only pc that shows a 5GZ network to connect to is the gaming pc. I assume because our laptops are old.

So my thinking was, even if the gaming pc is connected to 5ghz, it may not be exclusive to the gaming pc as the other devices may be switching between 2.4 and 5.

So from what you say it sounds like I might be better separating out 2.4 and 5ghz to have separate ssids. I have already turned on QOS and prioritised gaming for that. But have a feelign that the way I have it set up at the moment, the 5ghz could be used by all devices via router automated choice.

Ethernet cable is much better than any wireless connection, faster response time and much fewer errors.

Waste of time messing with Wireless. 5 GHz only may actually be worse as it will be combining maybe 4 channels rather than 2 channels at 2.4 GHz.

There are extra overheads to many channels which will increase response times, the opposite to what is required for gaming i.e. short response times.

Network speed is not the same thing as response time.

Cheers all. I've set 5ghz to a separate SSID and he can connect to either. The rest of the gadgets will then only be on 2.4ghz but I think it's been like that for ages anyway

Yes my old router used to show that but this new Asus wifi 6 one doesn't. I think it merges both 2.4 and 5 into one ssid due to the smart setting.

Anyway I've set 5ghz with a separate ssid now just for the gaming pc thanks. Yes ethernet would be better but would mean rewiring half the house . Part of the reason for getting this new router is the wifi is supposed to be much more stable. Hope that is the case.
