Obviously, more than our main laptop, tablet, and mobile phone were online. Things such as our Ooma VoIP phone and printer are always connected. In addition, three Google Home Mini speakers are constantly waiting on the 2.4 GHz wifi. Nowadays, I have three light bulbs and four wall sockets logged onto my 2.4 GHz network too. This is how I can keep them voice-activated without the need for any special hub.
I'm sure glad all these things do not have to fight for bandwidth over a dial-up connection!
