    Traffic lag issue on Intel Dual Band Wireless-AC 8260 and registry changes

      On Lenovo T460/470 Windows 10 laptop, ping or throughput latency problem is sometimes observed.

      Its network adapter Intel dual band wireless ac 8260 (with latest drivers 20.10.xx).

       

      I got to know by googling that the lag issue is due to frequent WiFi scan behavior of Intel Wireless drivers and it can be resolved by setting the following registries and setting 'Roaming Aggressiveness' to 'lowest'.

       

      "ScanDisableOnLowTraffic"=dword:0000001F

      "ScanDisableOnMediumTraffic"=dword:0000001F

      "ScanDisableOnHighOrMulticast"=dword:0000001F

      "ScanDisableOnLowLatencyOrQos"=dword:0000001F

       

      Changing 'Roaming Aggressiveness' to 'lowest' and changing values of the four registries make WiFi Scan disabled completely, then it leads to resolve lag problem.

      Does anyone explain about the four registries?

      And, is there any plan for Intel to update Intel Dual Band Wireless-AC driver to make WiFi-scan configurable?

       

      Thanks in advance.
