Dear All,

does the wireless adapter properties/LAN adapter have 'allow computer to turn off this device to save power' toggled on?

Dear Wullail,

No i had already unchecked those boxes.

If it's dropping connections both wired and wireless then you should perform a clean boot to see if the problem persists.

The directions in the link shows how to clean boot then disable start up programs that could be causing the problem. It's really just a process of elimination.

So much bloatware installed on new machines and these so called free programs cause endless problems, especially the trial versions of anti virus software which should be removed using the special tool.
