    slow connection on ac7265 with certain router

    JensOle100

      I recently bought an asus k501ub, we experienced a very slow internet connection from the start (12-18Mbps) when our other devices get (40-70Mbps). I tried updating drivers and put the pc next to the router but that wouldn't help.

      We have a second router upstairs and i did a speedtest next to that router which got the usual 65 Mbps.

       

      The problem occurs between the intel wireless dualband ac 7265 card and our b-Box 3 router. This b-Box 3 router can not be replaced because this is the router supplied by our ISP and is mandatory.

       

      I would like to know a way how I can solve my problem. Change settings? Change driver?

       

      I would like to thank you for reading my complaint.

       

      (sorry for bad english, from belgium.)

          Hello JensOle100,

           

          We understand your PC is getting a slow connection when connected to a specific wireless access point. Here are some aspects you can check about this.

           

          - The best source to obtain drivers for your system would be Asus Support, since they may have customized drivers for your PC. As second option, you can try the generic version of Intel® PROSet/Wireless Software and Drivers, current version is 18.40.4:

           

          https://downloadcenter.intel.com/product/83635/Intel-Dual-Band-Wireless-AC-7265

           

          - Check the documentation for your B-Box 3 AP and make sure it is using 5 GHz band for the network you are connecting to.

           

          - Confirm that you are using the configuration from the following advisory: Recommended Settings for 802.11n Connectivity.

            Thanks a lot for responding, I really appreciate your help.

             

            I downloaded the 19.00.1621 version of the drivers on the Intel website because Asus doesn't have any. And changed all the settings the guide recommended. The limited internet speeds are resolved now, but there is another problem.

             

            When performing a speed test it starts off fine (60Mbps) but after a few seconds, it drops to just below 23 Mbps. It feels like some software application limits it from reaching higher than 23Mbps because the graph shows a perfectly flat ceiling.

             

            This is noticeable in other applications such as youtube video's that have problems buffering midway through the video.

             

            I took a speed test to show you the problem:

             

            SpeedOf.Me Test Result  taken next to the router on the 5Ghz channel.

             

            Then another weird problem occurred. All further speed tests would get stuck during the test. This happened on all websites I tried and when downloading an image of google.

             

             

            My limited speed has been resolved, but now the speed is very inconsistent and downloads completely freeze sometimes.

             

            Thanks again for helping me.

              Hello JensOle100,

              I am glad to know you are getting better results now. Here are a few additional things for your consideration:

              1. The driver 19.00.1621 is for the Bluetooth* component of the adapter. Please install also the Intel® PROSet/Wireless Software and Drivers for Windows® 10, version 18.40.4.

              2. If you are not using Bluetooth*, try disabling it and check if this helps with the connection. This is normally done with a switch in the chassis, a key combination, or from Windows*.

              3. Other users have reported that some of the Windows* 10 features have an impact in network connectivity, you can try disabling these and test the connection again:

              - Windows 10 location service:
              http://windows.microsoft.com/en-us/windows-10/location-service-privacy

              - WiFi Sense:

                Again, thanks a lot for helping me.

                 

                I did download and install the 18.40.4 driver before the 19.0.x one. (on accident)

                Turning off the Bluetooth boosted the speed a little bit, but didn't resolve my problem.

                The windows features were all turned off as far as I know.

                 

                I went to the computer shop where I bought the laptop to resolve this issue. They couldn't help me immediately, but they took it in for 'repair'.

                They had exactly the same model on display and this one had the same problem.

                 

                The wifi speeds were alternating randomly between the maximum speed and a much lower speed.

                 

                Before going to the store I did some testing to make the issue clearer.

                Observations:

                          - the problem only occurs with my B-Box 3 router on both the 5.0Ghz as the 2.4Ghz channels (the B-Box 3 is a router+modem combo supplied by my ISP. I can't replace this.) (It does work perfectly           with my TpLink router.)

                          - the problem also occurred with the router at the store. (This is an expensive store, therefore I presume they have some high-end router hardware)

                          - I had infrequent dropouts. The download,speed test,... would just completely freeze until the page was reloaded.

                          - The internet speed randomly switches between the maximum speed (60-75 Mbps) and a much lower speed (usually just under 23Mbps).

                 

                (I have screenshots, but they are on the computer that I left at the store)

                 

                I hope this issue can be resolved.

                  Thanks for the update, please let us know the response you receive from the Computer shop.

                  We have seen other cases where older access points using 802.11n or 2.4 GHz band are not able to connect properly with the Intel® Dual Band Wireless-AC 7265.

                  For reference, we would like to add that disabling some of the newer adapter features may help in this situation. In Advanced Adapter properties from device manager, make sure to set the following:

                  - HT Mode:
                  Set to VHT mode when used in 802.11ac networks
                  Set to HT mode when used in 802.11n networks.

                  - U-APSD support:
                  Set to Enabled when used with newer Access points.
                  Set to Disabled when getting sporadic disconnections (normally with outdated 802.11ac routers or 802.11n networks).

                  - 802.11n channel width for band 2.4: 20 MHz only

                  Also, go to the Power options of you laptop, in the Advanced Settings for your Power Plan, then make sure that the Wireless Adapter is set to work at "Maximum Performance" when plugged in and on battery.

                    A lot has happened recently and after a lot of work, the problem has been resolved.

                    I did a lot of things to solve this problem. I went to the store, called my ISP multiple times, driver updates,...

                    So, the solution you have all been waiting for:

                     

                    Change the router.

                     

                    A technician came by my house (for free! thanks to Proximus!) because I had this internet problem. He did some diagnostics and tried replacing the B-box router with a  newer version. This resolved the problem! We now have a new router and the problem has been resolved.

                     

                    Thanks a lot for all the effort.

                      Hello JensOle100,

                      I am happy to hear that the issue has been resolved by replacing the Access point. I am sure that this will be helpful for other user facing this situation.
