    Intel Wifi 5100 - Windows 7 extremely high latency

    Ralph_T

      I have an HP HDX 16 laptop with Win7 64 bit that has been slowing down after coming out of Hibernation while on battery. To help troublsehoot this I am using the DPC Latency Checker program. With the help of the people over at the notebookreview.com forum I discovered that there is a problem with the Intel 5100 Wifi driver. I am using the latest 13.0.0.107 driver version. When disabled in device manger I do not see any remarkable latency. But with the device enabled I see latency spike to 32000 every so often. The link below shows the screen shot of this latency. The highest it got to on this test was 17000 but I have seen it much higher.
