My ancient TV isn't smart so I use an Android TV box to allow me to watch iPlayer, ITVX etc. My old box was based on ancient Android 7 and some recent apps were refusing to work. So I've just bought a (cheap) Android TV box based on the Rockwell RK3528 SOC.

However, it wouldn't connect to my hAP ax2 Wi-Fi. It sees the network but won't connect. Having been here before and got the t-shirt, I immediately suspected either AX or security. My private network has WPA2 PSK & WPA3 PSK authentication. The guest network has WPA PSK & WPA2 PSK. It wouldn't connect to either. If I turned security off and made it an open network, it connected. I finally narrowed it down to have WPA PSK and WPA2 PSK enabled. I set-up a separate virtual network just using WPA PSK and this works fine. I'm not overly worried about security - it's only used by this TV box and I suspect I can hide it once things have settled down.

But I guess my question is any idea why it can't connect to an interface when both security protocols are enabled? I thought the idea was that if a device could only connect to WPA-PSK, then it would ignore WPA2-PSK?

However, I suspect this chipset can use WPA2-PSK - after all it's relatively recent. So the problem could be connecting using the RouterOS implementation of WPA2-PSK?

PS. This chipset is used on quite a few single board computers but I guess the OS/device drivers running on them make a big difference.

If I can quote myself:

What is the point of running WPA2 and WPA3 on same network at same time? It doesn't matter that there are some clients connected over WPA3 when there is WPA2 still available. Security of your network is always the lowest one = WPA2.

Just adjust that to WPA and WPA2, idea is same..

And side note: it doesn't have to be issue with auth type but encryption, e.g. TKIP vs CCMP (AES)
