Resposta para "Why does my Acer R7 keep disconnecting from the internet?"Brian, After doing some research on on the R7, the WiFi card is a common issue. Finding a better card and replacing it would be your best option.

Trying to figure out why it is not working is more trouble than it's worth. For replacing the battery, try checking out the troubleshooting page here.
