    Intel Dual Band Wireless-AC 7265 performance issues?

    slaney31

      Hello,

       

      I've been having some issues with the AC 7265 card seemingly having throughput/connectivity issues.   I've reference the document AC-7265 Frequent disconnects/Painfully slow when connected and changed most of those settings.  I currently have configured:

       

      U-APSD Support - Disabled

      Transmit Power - Highest

      Preferred Band - 5.2Ghz

      Wireless Mode - 802.11a/b/g

      HT Mode - VHT

      Ad Hoc QOS Mode - WMM Disabled

      I've also configured the PC to not be allowed to turn of the network adapter to save power in the device manager.

       

      My wireless network has really good 5Ghz and 2.4Ghz coverage with 20Mhz channels only. I'm also running the latest driver for AC-7265 (8.33.0.1).  The scenario I came across today:

       

      • The card was connected on the 5Ghz frequency.
      • The laptop was connected for roughly 23 hours straight to the same AP.
      • The client was connected with very good signal strength of -63 RSSI with a SNR of 29 on AP1.  I observed really high latency and lots of ping drops from my machine to the cart.  I also observed that during a speed test there would be significant throughput drop that corresponded with the ping drops.  I did not see any issues  that would indicate any sort of wireless layer 2 issue. Whenever I tried to send any sort of significant data through the wireless cart is when I would start seeing the ping latency jump and ping packets not respond.
      • The client roamed to another access point AP2 where it connected with a better signal of -45 RSSI with a SNR of 46 (also on the 5 Ghz). I experienced the same exact same performance issues that I observed while connected to AP1.  Lots of ping drops and poor throughput when trying to send any data.
      • I tried to adjust a setting on the wireless card settings and that reset the wireless connection on the cart. I am no longer experiencing the performance issues I was seeing for the past 3 hours while connected to the same AP2.  My speed tests are almost 3 times faster after the WiFi card was reset by changing the setting.  Would changing the 2.4Ghz channel width from "auto" to "20Mhz" cause the network card driver to reload?  I changed this setting back to auto and I'm still seeing the much better performance.
      • There was no interference on the 5Ghz spectrum during this time.

       

      The fact that I witnessed this poor performance behavior on 2 seperate AP would lead me to believe that there is potentially an issue with the driver.  Has anyone seen this type of behavior with these cards?  Any input would be helpful. I believe we are experiencing this on a lot of laptops.

       

      Thank you,

          Intel recommends that if this wireless adapter is the one installed by factory, you should use the latest drivers provided by the OEM even though their version may be an earlier version that that we have available as they add customizations in order to be fully compatible with your system.

           

          We also understand you are using driver version 18.33.0. We have recently come up with a new driver version for this wireless adapter: 18.40.0 that contains a lot of fixes. For your convenience, here is the link: Drivers & Software - Please make sure to dowload the one that is right for your OS version and architecture (32 or 64 bit). Please proceed as follows below and let us know if this new version helped you resolve this issue.

           

          1.  Go to Control Panel, Programs and Features and Uninstall the current "Intel® PROSet/Wireless Software", if it is installed. When prompted, choose the option to "Discard settings".

          2.  Also in Programs and Features, Uninstall Intel® WiDi Software.

          3.  In Control Panel, Device Manager, Network Adapters, right click on the Intel® Dual Band Wireless-AC 7265 and Uninstall it. Make sure you mark the option to "Delete the driver software for this device".

          4.  Reboot the PC or scan for hardware changes, check device manager and if an older driver is detected and installed, repeat the actions to uninstall and delete it as well. Repeat this process until the OS does not allow deleting the driver, or until the controller shows as Unknown Device.

          5. Reboot or scan for hardware changes, then uninstall and delete any older driver versions as you did for the Wireless adapter.

          6. Install the Intel® Wireless driver. During the first steps of PROSet/Wireless installation,  make sure to customize the installation and install all the 3 driver components.

            I'm currently not using the Intel PROSet/Wireless software package.  Is there installation package that's drivers only like the 18.33.0? I've got a case opened with Dell as well to see what they recommend for this laptop. The other package with the drivers is easy to deploy because it requires no user interaction.

                  I purchased a HP Envy laptop in Sep 2015. Have had ongoing internet problem since purchase to this day. Switched providers, different routers, driver upgrades, and recommended device setup. Nothing corrects the problem. Upon startup, fast and responsive. With each additional move sites become slower and likely as not dropped. I am running Win 10 64 bit as delivered from Best Buy. I sure would like to find a solution to this problem. Don't think throwing money at it is the solution, unless it is a proven fix (maybe a new card to replace the AC 7265).

                        Pretty much described it in my post. I use Chrome or Fire Fox for browsers. Computer is HP Envy m7, Internet service was AT&T, now Dish satellite. Routers is Netgear AC750 R6050. Other routers and modems have been used in the past with the same problems I am still experiencing with present equipment. I involved HP support almost immediately after purchase. They made changes to drivers and made sure everything was setup correctly. Problem not solved. During the months of Jan, Feb March, and part of April, I used my ATT smart phone or tablet service to make hot spots for internet access. Still had problems. April 20, Dish satellite service installed, not change in performance. When I acces the internet I expect reasonable speed on accessing a site. As I use or move around the site, with each click it gets slower, takes longer to access new tab, until eventually I get the page not responding message. Its like being on a system where more and more people access a site until the site gets so slow it finally crashes, no more bandwidth. I have been downloading upgrades from HP support depending on the size of the file it may complete the download, larger files usually stall before finishing.

                         

                        Recent changes I have made involver HP driver 18.32.1.2 latest on their site. Used device manager to access AC7265 and made sure it was set up per instructions in other posts on this forum. The problem is with this computer. My daughter has used her Toshiba on my system and it works well. Hope someone can help.

                          After completing this post and clicking on send the computer stayed on loading so long that I finally clicked out (page unresponsive message). On returning to this site, surprised to see my reply had indeed posted. Don't know what is going on.

                            Marv,

                            Have you tried the latest version for this adapter? Consult with your computer manufacturer and check if they have their latest version: 18.40.0 for this adapter already available as their version may contain customized features designed to guarantee a steady connectivity.

                            Alternatively you may try our latest drivers found in a link sent previously on this thread (March 21st, 2016) as well as the steps for a clean installation.

                            Additionally, you may want to try changing channel to a less crowded one to see if any improvement is observed. You may even try the following:

                            1. Disable the Power saving Functions.
                            2. Go to Control Panel >> Hardware and Sound >> Power Option and set it to High Performance and apply to default settings.
                            3. Change the plan settings >>Change Advanced Power Settings >> Wireless Adapter settings >> Power Saving Mode >> and make sure both On Battery and Plugged in are set to maximum Performance.
                            4. Still in Device Manager >> Network Adapters >> Intel® Dual Band Wireless AC-7265, right click on it and select Properties.
                            5. In Porperties, select Advanced tab and set U-APSD support to Disabled.
                            6. Check Transmit Power and make sure it set to 5. Highest.
                            7. Set the Wireless Mode to 802.11 a/b/g according to the support mode ove your router.
                            8. Set the Preferred Band to Prefer 2.4GHz band
                            9. Set the HT Mode to HT Mode for 802.11n compatibility.
                            10. Set the 802.11n Channel Widith for 2.4GHz to limited 20MHz.
                            12. Set the Roaming Agressiveness to Lowest.
                            13. Set the AD Hoc QoS Mode WMM Disabled.

                              As stated in my previous posts, I have already carried out everything on your list except the 18.40.0 driver. It was not listed on HP driver support site... yet.I believe the only fix for this computer would be a compatible wireless card to replace the Inter product. Unfortunately I don't know what that would be. THe only good thing is my ethernet connection works fine.

                                    The procedure listed above is very complicated for me, not that savvy, and old. If I try to carry out the instructions, I will need the confidence I can get everything back up and working. Got to wrap my head around the fact I have to try and fix something I paid a lot of money for. HP should be doing this, not me.
