    Intel Centrino Advanced-N 6235 card working slowly on Windows 10

    Matsomppi

      I have a few years old Samsung Ultrabook laptop, which has an Intel Centrino Advanced-N 6235 Wifi and Bluetooth card.

      After updating to Windows 10 I haven't been reaching proper Wifi speeds with my laptop. At the moment I can get 50/50 down/up from my Wifi

      with my cellphone or my tablet or an another laptop, but with this one I get something like 7-15/10 down/up. I've tried to install the Windows 8.1.

      drivers (version 18.40.0) but they dont seem to install, since in the Device manager I seem to always see the Windows 10 native drivers (version 15.18.0.1).

       

      What to do to get my wifi working properly?

          The Intel® Centrino® Advanced-N 6235 utilizes Windows® 10 own inbox driver by default.
          We recommend to first contact your computer manufacturer in order to obtain the latest driver. You may find their contact information in this link: Computer Manufacturer Support Website

          Please, test the latest driver provided by your computermanufacturer and then let us know if they worked for you. We are looking forward to hearing from you soon in order to see if more support will be needed.

            Samsung isn't on the list you've posted, and Samsungs site only has drivers for Windows 7, for this laptop.

            How can I install the Windows 8.1 drivers or can I?

              Matsomppi,

              Thank you for your observation. We are informing the web administrator about this. Regarding the support for Samsung*, here is what we have found in order to help you to contact your computer manufacturer: Samsung* Support - One you are there, please scroll down to the part where it says What Product Do You Need Help With, under this option, you will find several other options and among them you might want to select the option that says PC & Office. *Important to mention that you need to consider your region in order to obtain the proper support from them.

              As for the drivers for the Intel® Centrino® Advanced-N 6235, you are welcome to visit our support page. For your convenience, here is the link to it: Intel® PROSet/Wireless Software and Drivers for Windows 8.1*. - Driver version: 18.20.0 - Make sure to choose the file according to your OS architecture 32 or 64 Bit

              *This driver is generic and Windows 8.1* compliant so it may not contain all the necessary adaptations required by Samsung*.

              NOTE: There is no need to click on the yellow stripe that informs about  a newer version of this software as the later version is designed for other adapter models.

                Matsomppi,

                It's been a while since we sent you the recommendations above and so far there is no record of any interaction from you. We were wondering if you still need our assistance. Please let us know as soon as you can or at your earliest convenience.

                  Thank you Matsomppi for your response.  I also have the same issue with the slow performance of the N 6235 on windows 10. I have downloaded the  Intel® PROSet/Wireless Software and Drivers for Windows 8.1*. - Driver version: 18.20.0 and successfully installed however I am still facing the same performance issue.

                   

                  Other things that I have tried to solve the problem:

                   

                  -installed driver versions  15.18.0.1 through windows 10.

                  -uninstalled intel pro set software and reinstalled.

                  -manually deleted the adapter and the driver files from my hard drive (netwew01.sys, netwfw01.dat)

                  -connected to a different wireless access point.

                  -tried variations on both wireless access routers to “auto channel” and fixed channel.

                  -tried variations limiting both wireless access routers to “b” “g” “n” standards

                  -tried variations on both wireless access points to completely remove security or use WPA-2

                  -alter power management settings to provide maximum performance for wireless networking

                  -disable the Bluetooth radio.

                  -change antivirus programs

                  -disable antivirus programs and other programs that use network bandwidth.

                  -used Samsung support to receive the latest drivers from Samsung.

                  -searched Samsung support site for wireless issues with the NP740u3e model.

                   

                  Using other laptops and cell phones I am able to attain speeds close to 40mb download per second on the same wireless network.  Using my laptop I am unable to receive speeds above 5mps download and often am getting speeds of less the 1mbps.

                   

                   

                  Thank you in advance for your help.

                    Windows®10 has a feature called WUDO (Windows Update Delivery Optimization) which is a great idea to hel users to get faster software updates. It works a lot like torrents work.

                     

                    A computer running Windows®10 is used as part of a peer-to-peer network to deliver software updates faster as each computer distributes a little bit of the files across multiple computers and in this way, helping everyone to download updates quickly.

                     

                    Please, access this link provided by Microsoft* for more information on this feature: Windows Update Delivery Optimization: FAQ

                     

                    In so doing, it may use a lot of bandwidth that consequently may affect the connection. The picture below illustrate how you can disable this feature. Please, disable it and test your connection.

                      Thank you. I checked the setting and this was already turned off.

                        In this case, you want to take a look at these online solutions.

                        Please bear in mind that the support for this adapter on Windows®10 is offered by this OS own inbox driver and the drivers found in our download center is Windows* 8.1 compliant as you can confirm here: Intel® PROSet/Wireless Software and Drivers for Windows 8.1*.  *Please ignore the yellow stripe informing about a newer driver version as it is applicable to other adapter models. *Conact your computer manufacturer for additional support as well. You may find their contact information through this link: Computer Manufacturer Support Websites

                         

                        On our best effort to assist you, here are some tips that might help you improve you experieince:

                         

                        1. If possible, test different channels - to further reduce interference, be mindful of other wireless networks in range that may be competing on the same frequency. Many current Wi-Fi routers are pre-configured to use the same wireless channel (6), and it can be very congested if you are in an environment with other networks. Do a wireless survey of your area and use a channel at least 3 channels away from those used by other networks in range to avoid interference.

                         

                        2. Keep the router clear from interference - most routers/modems/gateways are not well shielded against electro-magnetic inferference, and they'll work better when away from any possible source of EMI/RFI. Keep your router at least one foot away from any other routers, modems, switches, computers, monitors, power supplies, fans, fluorescent lights, cordless phones, etc.

                         

                        3. Improve signal strength - it is best if wireless access points are at an elevated point, at least one foot away from any surface that may reflect or attenuate a significant portion of the signal, such as metal/foil insulation, wire-mesh stucco on exterior walls, etc. If installing near the edge of a building, there may be an advantage to using a directional antenna, or building a simple reflector using aluminum foil behind omnidirectional antennas to focus the signal. This is less of an issue with some newer 802.11ac wireless routers capable of beamforming with built-in phased arrays. If your router/ap uses removable external antennas, another easy option to improve signal is simply replacing them with longer/stronger omnidirectional antennas.

                         

                        Best regards,
