1) Get the latest network driver from (
important) -
Download Drivers and Manuals | Acer Official Site
If you need the model information, shut down and hold the volume up button on the tablet and then press & hold the on button, once the logo pops up, hold for a few seconds and you will get into the bios. It should display the information on the front page. Alternatively look at the product information booklet(s).
2) Open "This PC", you can do this by using file explorer and the quick shortcuts on the left hand side.
3) System properties -> device manager
4) Tap & hold on the network adapter in questions and press uninstall (tick the box that says delete this driver).
5) if prompted to restart, restart.
6) Extract and install the driver downloaded at step one.
This may help resolve this issue, let us know how you get on :).
