Losing internet connect during sleep

Lugwalker

Every computer or laptop I've owned kept its internet connection when it went into sleep mode.  When I woke up the computers I alway had the internet still there.

 

When I bought my new Acer Veriton X4620G a year or two ago the first thing I noticed was that whenever I woke the computer up from sleep after I had left it for a while, its internet connection would be gone.  This would require me to click on the internet icon in the taskbar to get connected again.  This issue has continued to this day.

 

Can anyone tell me how I can get my Acer Veriton to keep its connection to the internet when it goes into sleep mode?  It's such a nuisance to have to click on the network icon and wait for it to reconnect every time.  Neither my wife's laptop or my own laptop or any othe computer I've had do this.

 

Why is this happening with my Veriton?  

 

Thank you.

The only thing which works for me is leaving my email client and my browser open.  When I wake the computer from sleep after an absence the connection is still there.
