Russell, I believe I have the same iMac 21.5". I get a few disconnections, not
often, not as often as you are getting.
If it happens I would go into the extra menus into wifi, turn it off then go
back in and turn it on again.
Only other suggestion is to turn your wifi router completely off, disconnecting
the power plug for 30 seconds then turn it on again, this may reset any errors
in the modem.
I am using bluetooth keyboard and mouse is connected though I don't use it.
I suspect the router/modem and suggest you ensure the problem is not with that
rather than your iMac.
Can you hardwire connect to the router ?

Hi all,
I know at least one other person on this list has the same iMac I just
purchased last June, an iMac 2017. I’m having issues where my WIFI keeps
disconnecting. It shows as being connected when I look at the WIFI icon in
menu extras, but I am not able to connect to the Internet or send/receive
email. It first only happened when waking my iMac from sleep, but now it
seems to be disconnecting randomly, while I’m using my Mac. I can’t pin down
exactly when this issue began. I didn’t have this issue when I purchased my
iMac last June, and I don’t think it started when I first installed High
Sierra, but I think perhaps one of the High Sierra updates may be the
culprit. I’ve been on the phone with Apple quite a few times with no
resolution. On my last call they wanted me to turn off Bluetooth and see if
the issue went away, but I don’t have access to a wired keyboard, so wasn’t
able to do that.
Has anyone else experienced this issue, and, if so, have you found a fix?
Thanks in advance.
