    Intel wirless ac 9260 download speeds are very slow

    rishisood

      Hi,

       

      I bought a dell precision 5530 which has the intel wireless ac 9260 installed. The wifi speeds on the adapter are very slow sometimes topping off at only 8MBps whereas my latitude e7420 with the intel dual band wirelessac 7260 has speeds of 100MBps. I use the netgear router wn614. I have the latest driver from your website installed am not being able to figure out what the issue is and what is causing the slow download speeds. Please help

            Hi Wanner,

             

            I checked the router firmware and it is up to date. Have attached the scan log to this reply.

             

            Thanks

                Hi

                The driver that you have recommended is a bluetooth wireless driver.I have installed the same and the speeds still remain the same.

                 

                My system is the Precision 5530 with windows 10 enterprise 64 bit installed (version 1709 - OS build 16299.194).

                 

                Thanks

                  I just observed another thing, the wifi just disconnects for a couple of seconds and then connects again. This is happening regularly.

                   

                  Thanks

                    Hello rishisood,

                    Thank you for pointing out the wrong driver. Were you able to install the latest wireless driver from the same support website?

                    If the issue still persists using the latest wireless driver provided by your system manufacturer, try performing a clean install with the latest Intel driver:

                    For Intel® Wireless-AC 9260
                    Version: 20.90.0 (Latest)

                    Then, you can use the Recommended Settings for 802.11ac Connectivity

                    **Note: We supply generic versions of graphics drivers for general purposes.  Computer manufacturers can change the features, incorporate customizations, or make other changes to the graphics driver software or software packaging.  To avoid potential installation incompatibilities, we recommend that you first check with your computer manufacturer and use the driver software provided.

                      Hi Wanner,

                       

                      I completed the clean install and used the recommended settings for 802.11ac Connectivity. The download speeds are marginally better but still not close to the speeds i get on my latitude system.

                       

                      I was looking at the network properties and found that under wifi the link speed is only 54Mbps (screenshot attached). Where can i make this 300Mbps.

                       

                      Thanks

                          Hello rishisood,

                          Thank you for your response.

                          While the wireless adapter on your computer supports 802.11ac standard, the WNR614 supports the 802.11n standard. This difference in hardware can affect the performance of your download speeds.

                          A. In Device Manager, try changing the 802.11n/ac Wireless Mode to HT=High=802.11n.
                          B. Is your access point (AP) or Wi-Fi router for 11n mode?
                          C. Set the adapter to Maximum Performance.
