Hi Jasmine,

This still sounds like a driver issue to me. Try downloading the drivers from the Acer site and following the Identify the drivers you need instructions (fill out the fields appropriate to your machine). There site is here:

https://www.acer.com/ac/en/US/content/drivers

Then install the drivers from the location you downloaded them from and hopefully you will be up and running.

If this doesnt work try a WinSock and TCP/IP Refresh by doing the following:

1) Type "Cmd" in the Start Search text box.
2) Right click the CMD shortcut and choose "Run as an Administrator".
3) Type
netsh winsock reset
in the Command Prompt , and then press the [Enter] key.
4) Type
netsh interface ipv4 reset
and then press [Enter]
5) Type
netsh interface ipv6 reset
and press [Enter]
6) Type
ipconfig /flushdns
and press [Enter]
7) Finally, restart your computer.

Let me know how it goes.
