Internet connection in my acer v5 571 unstable

I am having same problem constantly goes off yet i have no problems with 3 other puters in the house and numerous other things on my wireless..

I was having the same issue.  I found a possible solution on another board.  Is this happening only when on wifi when you run on battery power?  That was the case with my computer. The solution that was posted was to go to control panel - device manager - network adapter - Qualcom Atheros - double click - click tab for Power Management at the top - Uncheck the box that says allow device to be turned off to save power (or something like that. You'll know it when you see it). I haven't had any problems so far since doing that.  I tried everything else.  I had the most up to date drivers, had uninstalled and reinstalled the adapter and drivers and nothing else worked.  This has helped so far.  I was losing my wifi connection every 15-20 minutes or so.  Had limited connectivity.  Acer phone support was useless.  First they had me uninstall the device and remove the drivers.  This caused the network adapter to disappear completely and would not reinstall when restarting.  They then wanted me to format my hard drive and reinstall windows. They said it was the only way to get  the adaptor back.  Apparently, they forgot about using a restore point instead of wiping out my machine. I will say that I also took some other advice and ENABLED the Bluetooth Module in Device Manager.  Just click on the Bluetooth in device manager and you'll see an ENABLE button on the bottom of the pop up screen.  Apparently there may be a conflict with antenna switching if the Bluetooth is DISABLED. Hope that helps.  I'm keeping my fingers crossed.
