Samsung Series 9 Wireless Issues

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.

Samsung Series 9 Wireless Problems

The issue is by default the power saving mode is either turning off/preventing the wireless adapter from connecting.

Step 1

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.


Step 2

Then click on “Change Advanced Power Settings.”


Step 3

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!

Also I recommend downloading the newest drivers from Intel here:

Also make sure you don’t have a proxy server enabled under Internet Options > Connections > Lan Settings

  • thanks for taking the time to post this! unfortunately it did little to improve my wifi issues, the connection still drops way too many times. are there any alternative fixes one could try? many thanks! 🙂

    • I currently don’t have any issues on my Samsung laptop. It could be a bad combination of drivers. I recently did a fresh install and only installed the WIFI driver and the Easy Settings software (to get the function keys to work). Everything else I simply relied upon Windows Updates to grab. I have a feeling Samsung has a buggy driver. I am at Starbucks all the time and on wireless for hours. If you ever get to the point of doing a fresh install again, try installing just those two and let everything else self update.

        same here, i did a fresh install of win8 after replacing the msata ssd with a larger 256gb and then i used the samsung software to update/enable the basic ultrabook functions. i also believe that the samsung wlan driver is buggy thus i have uninstalled/disabled it but again it did little to improve the situation. this is driving me nuts! i’m currently thinking about exchanging the wlan adapter …

          i am having the same issue, i did the above but to no avail. this is my work laptop now and is driving me mad. whats the point in a super fast laptop if the internet is slow and dropping connections

          • What model of Samsung do you have and WiFi card? I am running NP900X3B and the Intel Centrino Advanced-N 6230 WiFi card.

          • drunkenmaster

            I have a NP900X4C with an Intel(R) Centrino(R) Advanced-N 6235 wifi card… I have reset the tcip stack and updated the wifi card driver. There were some updates from samsung recently that i hoped would sort it out but no. I keep getting these events like this in succession:
            Name resolution for the name wpad timed out after none of the configured DNS servers responded.
            WLAN Extensibility Module has stopped.

            I also have gotten a few blue screen notifications… could this be a hardware issue do you think?

            Hi guys/gals .. many issues with Wireless connection dropping (limited connection) across all hardware platforms. Most hardware/wlan adaptor updated their drivers. But currently (July 2013!) the problem still not fixed on the Advanced-N 6230 WiFi card.

            Come on Samsung! get it fixed!

          • Wherez Waldo

            lol the series 9 is not a super fast laptop. it is an i7 processor that has a quadcore and samsung disables 2 cores with their firmware.. .you are looking at a dual core running at less than 1.9ghz though an ssd can give the illusion of fast processing .. but the cpu itself is circa state of the art desktop speed circa 2005

    hi, Thanks god my wireless is fine.;) but I would like to report other issues i had with the samsung series 9 , NP900X3C (with W7)
    I got 4 problems:
    1) when i got the np900x3C the keyboard failed in one key so I got replaced with the new one in the shop.
    the second device (which I have now) have 3 problems:
    2) two dead or stuck pixel ( :-/ )
    3) the speakers make a noise: something is vibrating inside the case so it results in a distorted sound. If keep pressing the lower part of the case with my hands the noise disappear so seems 2 metallic piece inside the case touch each other in a wrong way. now i have to go to samsung assistance again.:(
    4) the laptop doen touch the desk properly: one rubber feet does not touch the ground so making the laptop swinging when typing.

    Four hardware problem in 2 device is a very hi percentage of hardware failure. but overall i love this laptop.
    Should I go to the exorcist before the Samsung service center? 😉

    • Wow sorry to hear about all your problems Anjo. Sounds like you got a bad apple. Other than the wireless issue which I remedied, I haven’t had any of those other issues. I definitely would recommend an exorcist lol…. and when that doesn’t work I guess your left with the Samsung service center. With that many things wrong and if you are under warranty, I would push them to simply replace your whole laptop. Good luck! Thanks for posting.

    I have one month old Series 9 laptop and the Wifi is dropping all the time. I have had 4 different laptop before this and none of them have had this kind of problems. I also had problems with keyboard dimming but I fixed it through power management settings.

    • Did you try our solution above? Also, you might want to try disabling power saving on the wireless NIC.

      Step 1
      Right click on the network adapter, go to properties.

      Step 2
      Click on Configure.

      Step 3
      Go to the Power Management tab and uncheck “Allow the computer to turn off this device to save power.”

      Hopefully that helps!

    Hi Brian. I have a Samsung NP900X1B ultrabook with Intel Centrino Advanced-N 6230 WiFi card and the same connectivity issues mentioned in this forum. Have tried your power setting adjustments and also a complete reformat with the driver re installation but the wireless adapter still drops off sporadically. Is this network adapter replaceable or is it integrated with the motherboard?

  • BK

    stay away from this product – the wireless is so crap and it’s too much of a headache trying to fix it. I’ve changed the power settings…it didnt help. the connection still drops out…its a waste of time and money NEVER buy Samsung laptops…they suck..the battery is shit too. what’s the point of a laptop that has a shit wireless connection????? -1/10

    I had the Same issue with a Series 5 Ultra Book that I was able to fix. Dont worry it is a setting Problem that was placed incorrectly by Samsung. Click Start, Search for Internet Options, Connections, LAN Setting then Make sure to have Detect Automatically select and the other two options are unchecked. In My case the Automatic detection was not checked and as soon I selected it my performance meeted by expectations with this Laptop. The Wifi Connection was annoyingly sluggish when this feature was turned off In other computer such as HP, Lenonvo or Dell. This feature is automatically selected, so double check that especially if you purchased it used. You can further optimize the wireless performance by going to advanced settings under power options and by selecting wireless option and setting it to maximum performance. There are some articles currently available about the procedure Good Luck!!

    I LOVE YOU BRIAN LEE JACKSON. I was killing myself trying to figure out why a Unifi Wireless network I was setting up for a customer was SO SLOW. It wasnt the network, it was my laptop running off battery. As soon as I made the change you describe above, results improved 10x !!!!!

    Hi Brian, I have a Samsung Series 9 that is three years old. I also have a new dual band router and want to connect the Samsung to 5GhZ but it is not supported by the Broadcom 802.11n adapter. Is it possible and feasible to swap the adapter for one that will support a 5GhZ connection?

  • Helge

    Hello all,
    I have this new Ultrabook 9 series running i7.
    First I loved it(less than 2 days before my problems) but now I start to hate it and seriously want to just dump it.
    The wifi is the worst ever and I am writing this on my old Apple air sine that works with my network. my new Samsung can not even connect to write this post. 🙂
    sad sad story as I use my pc for work everyday and right now I am lost.
    I tried the above it does not work at all for me. I have reset the wifi adapter and it will not work and every time I open my phone, my apple air or even my very old Sony it all works but this new Samsung…..Any help will be highly appreciated.

  • Ayal Ronen

    Hi Brian, I seem to have the same problem. I have a Samsung series 9 laptop and I get a bout 1/3 of the wifi I should be. In comparison, my wife has a Macbook pro which gets the full wifi (30Mbps). I tried editing the power plan as suggested, but that didn’t make a difference. Any other suggestions? the model number is NP900X3D-A06CN. Any assistance is greatly appreciated!

  • hardright

    Had the same issue. Went to Intel site and downloaded the latest drivers for Win10. Used another PC to do this. Ran the driver setup on the S9 and problem solved.

    Seems like it helped on ‘nix also.
