WPA3 issues - older device.

[Mr+Slant]

Basically the issue is that there's a certain brand of solar/battery inverters who use a wifi dongle (2.4GHz) which can't deal with WPA3.

To make matters worse it doesn't actually retry when initially deauthed so WPA2/3 (WPA3-T) mode doesn't work. Note that this kit based on a chipset from about 2012/2013 so regardless of firmware support its not happening as the hardware can't do it.

Now you can of course set the wifi security to WPA2 which isn't what you'd call insecure but as all of these older devices are on 2.4GHz I wondered  whether it was possible to set WPA3 on 5GHz only, whether by a change of SSID or whatever.

Haven't used a Sky router in a while so I thought someone might know what options are available in the latest couple of routers.

Unless I'm mistaken it isn't possible to split the 2.4 & 5GHz bands into seperate SSID/networks, or to apply differing encryption standards to them. It's either WPA3 for both bands or WPA2 for both. You'd need to use a third party WiFi access point instead of using the Sky WiFi Max router for WiFi if you want/need to handle the two WiFi bands seperately/independently of one another.

Nope: only the Max Hub does WPA3 anyway (because there's a hardware requirement for that which the Sky Broadband Hub doesn't meet) and as @CoffeeDrinker indicates it's not possible to unsynchronize and rename the wireless bands on it.

Thanks peeps, that's pretty much what I expected but good to have it confirmed.

Third-party WAP looks like the way to go then.
