Hi tuddrussell and welcome to the forum :flower:
While that is a proven route for compatibility, it is a little too late for such an advice for tmc8080 :iagree:
There is a general trouble with Wi-Fi and sleep mode and of course it makes the question very hard to answer. It could be down to a driver problem (check for updated Acer drivers, try the original Atheros/Qualcomm driver and check if Microsoft have drivers by uninstalling the driver using device manager) and even the router could play a role (try to disable VMM in the advanced Wi-Fi settings for testing).
Personally I do not have access to this particular card and so can not try to replicate his challenge.
In this respect, any advice such as the above would be general and so I initially hoped that someone with the card would answer, but while I believe the laptop to be installed with Windows 10 home, there is no information thereof in his request which may have kept others from replying.
Fwiw, since pressing the reset button helps for a while, I think it is a driver issue and/or a BIOS update needed
