    Problem of Dual Band wireless AC 7260 on win8.1

    iamnotakiwi

      Hi all,

       

      I am having an issue with my brand new thinkpad new x1 carbon. I am running win 8.1 64bit version. The problem is that whenever i restart/shutdown my pc, it does not have wireless connection any more. In the device manager, it shows a yellow ! saying:This device cannot start (code 10) {operational failed}
      But when i disable and re-enable the device(reinstall the driver also works), the wireless connection become avaiable again. Seems that it has some problem at every reboot. My driver version is 17.0.3.2
      Looking forward to your replys!!!
      Thank you!!

          Have problems with the same card on my NUC. I have a Asus RT-AC 66U and get 0,7 Mbps on 5 GHz and round 50 Mbps on 2,4 GHz but drops. In the Windows 8.1 device manager/Advanse I can only see 40 MHz, not 80 MHz. AC is 80 MHz. Distance between the NUC and the router is 100 cm (40 inch).

            I fix it with a USB-WiFi card I bought 2008. A terrible card when it come out but today with Windows 8 automatic download driver its a nice one. Better speed and reliability then Intels new AC 7260. Only 5GHz N but good speed like 70-90 Mbps

              Did you guys try updating the system BIOS or AP's firmware?

              BIOS updates for some of the latest Intel® NUC models provide new power management settings.

              There is also the option to disable uAPSD from the wireless driver’s advanced properties tab. However, I am not completely sure but it seems that the issue iamnotakiwi has is not the same as the one stormense has.

                thanks for your reply. I have updated the BIOS, it doesnt seem to solve any problem... what do you mean by AP's firmware? how do i do that?

                I have also tried to disable uapsd, no hope at all.

                I have tried any possible solution i could think of, updating all the windows updates etc... none of it solve the issue...

                any other sugguestions you guys can think of, please let me know!

                 

                Many thanks!!!

                    Hi Joe,

                     

                    Thanks for your consistent support. I donubt it is the problem of the router, coz no matter which router i connects to(home, work, starbucks), the problem persist.

                    Hope that you will have clue from the logs.

                     

                    P.S. i searched through microsoft communities, I found quite a few similar issue reportings, but sadly none of them give a promising solution...

                     

                    thanks

                      I see you have the latest driver but did you try uninstalling it and reinstalling it. This issue seems to be mostly related to software corruption somewhere.

                      You can also try repairing the TCP/IP stack: How to reset TCP/IP by using the NetShell utility

                      Let me ask, did this work properly before? If yes, what changed?

                        I tried to install/uninstall the driver for many times, didnt solve the problem.

                         

                        i wasnt able to reset the tcp/ip stack(running as admin):

                        I doubt i have changed anything, this is a brand new laptop with minimum configuration, i even tried to reset everything to factory setting. but the problem still exists.

                         

                        not sure what i can do.. maybe install win7 instead?

                          Unless your system is part of a domain that restricts this type of access, such result from the netsh command indicates the possibility of a tainted or corrupted operating system.

                           

                          How did you restore your computer to factory settings? Was everything else deleted after such process? If the answer is no, there is a chance of virus in your system, otherwise it could be hardware related.

                            I have never seen such a collection of bad advice and complete misunderstanding of the question asked.  Update the router firmware when your driver is not loading??  Complete malpractice. 

                             

                            Stormense:  Please don't post anything ever again.  Thank you.
