An external aerial does seem reasonable - reception inside a metal case will surely always be poor?
I think the WLAN module is sitting on something called a MINI PCIE1 connection, similar to that shown in this picture, but not identical:

Mine has a black wire coming off the module that goes to a black plastic lump attached outside the back of the PC. It also has a white wire attached to the module that leads to the front of the PC but I can't tell where it goes. Maybe one of those is an antenna? And the other one is bluetooth?
Yeah, sounds like a reasonable guess. Okay, so reception ought to be fine.
The other devices do seem to swap between connections on 5 GHz and 2.4 GHz depending where they are in the house, so I guess signal levels may be marginal.
I googled "acer RTL8821AE" and I saw a couple of hits such as "keeps dropping copnnection', "wifi constantly dropping". Not sure if that helps.
Dunno. I realized that I have a Raspberry Pi sitting underneath my desk at the moment, so I enabled wi-fi on that and it seems to work without a problem. So I'll give up on trying to get my PC to work I think.
The wifi "aerial" on the Raspi is part of the pcb, quite some intricate trickery. If that works, there's probably nothing wrong with your wifi signal.
Next step is to learn how to secure the wi-fi on the Pi. I only want it to be able to make outgoing connections; nobody should be able to connect to it.
Assuming you don't have fixed ip addresses, i.e. you are behind a NAT gateway, that should not be a problem (unless you are also worried about internal traffic). Depending on what you are running on the Raspi, it won't have much open either - probably only sshd.
And I'd specifically like to prevent ssh sessions using that interface; they should only be possible using the wired interface. I've no idea whether either of those goals is doable.
Put a ListenAddress in sshd_config. The default is to listen on all addresses.
