    D34010WYKH with Intel Dual Band Wireless-AC 7260 Issue

    Biskitt

      Hi,

       

      I have recently purchased a D34010WYKH which I have installed with 4GB 1600MHz DDR3L 1.35V RAM, Crucial 120GB mSATA SSD, A Western Digital Scorpio Blue HDD and the Intel Dual Band Wireless-AC 7260 adapter. I have installed Windows 7 Professional and everything is working fine except for the really poor wifi speeds I am experiencing.


      I am on 60mb fibre optic broadband and I am only getting 3mbps speeds download speeds on Speedtest on my NUC yet I am getting approximately 20 -30mbps with other devices in exactly the same location ( I have tested this with a Samsung laptop, an Iphone 5s and an Ipad Mini ). Oddly, the upload speed on my NUC and other devices all appear to be very similar ( 3-4 mbps ). I have installed the latest drivers for the wireless adapter as well.

       

      I can't change the channel to 5ghz as my laptop doesn't support this so just wondered if anyone had any ideas ? This is the first PC I have ever built and i'm not an expert at all on these matters so any help would be greatly appreciated.

          There appears to be an industry wide problem with the 7260 line of cards. I suspect its a hardware problem given that it has been known for a long time and Intel has not been able to fix it.

           

          I am the proud owner a NUC 2860 and a Toshiba Z35 with this card and both have the same problem.

           

          If you can send it back, I would get something else. If not, you might try this:

            Hi Biskitt, I understand the inconvenience you have encountered with the wireless connectivity.

            I would like to suggest updating to the latest BIOS version 0025.

            Users from other threads in this community have reported an improvement with driver version 16.8.

            We are working on a solution for the issue you have described.

              Hi Joe,

               

              I have the latest BIOS installed already ( I did this before I installed anything else ). I'm not sure that the Dell Drivers you linked to will work as well as the say that they are only compatible with Windows 8.1 and I am running Windows 7.

               

              Thanks LesMoss for the tips, I will look into that. Very disappointing from Intel to say the least

                We expect a new driver release soon. Please stay tuned and thank you for your patience.

                  I just installed driver version 17.0.0.34 and while it seems that the adapter is now functional after resuming from sleep, the latency spikes still exist. This is what I see when I ping my gateway over 2.4 or 5.2 ghz wifi. When using my older intel wireless nic, the max latency I see is 2ms. These drivers still need work....

                    May I ask what is the AP brand and model? Do you know if this issue happens with different APs?

                    What is the throughput you are getting? Please indicate channel width being used.
