I just received the new Samsung Series 9 laptop/ultrabook at work and am completely in love with it. The first issue though that I noticed was that the wireless was cutting in and out, or behaving very slowly. To fix this simply follow the steps below.
The issue is by default the power saving mode is either turning off/preventing the wireless adapter from connecting.
Go to your start menu and search “edit power plan.” It should give you a result of “edit power plan” at the top of the start menu to click on.
Then click on “Change Advanced Power Settings.”
Under Power Saver mode, go down to the Wireless Adapter and change on battery to Maximum performance. (you could try ones in between too. Myself, a laptop without internet is useless, so I want it to be as fast as possible)
Your wireless should now work again! Also, you could try going to device manager and un-checking the option for power management to disable the device. Hope that helps!
