It’s unlikely to be a device limit, you can in theory have over 200.
I am assuming from the question, you have lots of devices connected to the hub, It could be a simple ip clash if the other devices are using fixed ip addresses. Next time it happens, log into the router by typing the router IP address into a browser. The default is normally 192.168.1.254.
On the router webpage you should be able to see what devices are connected to the router, it also tells you if the router is connected to the internet and you can manually reconnect if it’s not. You don’t need to login as admin to do this, so you can’t break anything,
Check your windows pc is not using a fixed IP address - google how to do this. I think the first 74 address on the Plusnet router are reserved, so make sure the PC is not using one of these. Also make sure it’s in the same domain, I,e, the first set of three number in the IP address are 192.168.1.xxx
Something I would do is give the 5Hz and 2.4Hz different ssid names,so you can control which you connect to. You will need to login to the admin screen to so this. There are lots of guides on how to do this. The 2.4Hz is more reliable, and goes further, however this can cause other issues in built up areas. I would use the 2.4Hz with win10.
