Try this. Go to Device Manager. Under Network Adapters, for every single adapter that has a yellow exclamation mark or red, right-click and uninstall the adapter. Especially WAN Miniport. Save all open files and restart the computer. If you continue to have difficulties, let us know.
To open Device Manager quickly, go to Start -> Search -> devmgmt.msc
The fact that you have WAN Miniport (Network Monitor) #2
should be indicative of the problem. The second one is likely unable to start because at some point, the first one may be initializing. If you only see one, you should still remove it and confirm that you still have working network access. I believe, in your circumstance, it would be very unlikely that you have a problem.
When you are in Network Adapters under Device Management, also try to right-click on any wireless network adapters and controllers. Make note of these and please report back what you are listing. The technical specs page from Samsung only lists:
- 802.11bg/n* Wireless LAN attached
It does not list the make and model of the adapter. Sometimes, late in production, many retailers will switch out the hardware based on the cheapest they can find. This can include the motherboard, if the component is attached. Also, the Samsung Support site is not showing your model with any Windows 8 downloads.
Here is what you can do. Check here: http://www.samsung.com/levant/support/model/NP-R439-DA02JO-downloads
After deleting WAN Miniport,
You can download the WiFi adapter drivers from there. However, these are Windows 7 compatibility drivers. You need to get the latest drivers from Realtek and Intel.

Realtek WiFi Drivers: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=13&PFid=21&Level=4&Conn=3
I need you to get the network adapter information from your system. One of the most comprehensive ways to do this is a program called Speccy
(freeware), or, preferably, AIDA64
(trialware but will work). Then you can determine exactly which driver you need to "update". The WAN Miniport cannot initialize, but this does not mean it absolutely needs to be updated. As I said it is not real hardware and it is a way for Windows networking to manage virtual private networks and dial-up connections.
All the best with this.
