<< Intel << Intel Roadmap << List of Intel Wireless Devices <<

Slow Throughput w/ Intel WiFi
Problem: Intel enabled Receive Side Coalescing (RSC) in their 18.x drivers
 * Solution: (Windows 10 Creators Update v.1703)


 * 1. Manually disable RSC by issuing the following in an Admin PowerShell terminal
 * First, garnish the WiFi adapter name:
 * Get-NetAdapterRsc
 * Then, insert that name in lieu of :
 * Disable-NetAdapterRsc -Name 
 * If this does not fix the issue, continue to Step 2.


 * 2. Change WiFi MTU value to 1400
 * Determine interface MTU value
 * netsh interface ipv4 show subinterfaces
 * If value is 1500:
 * netsh interface ipv4 set subinterface "" mtu=1400 store=persistent
 * If this does not fix the issue, continue to Step 3.


 * 3. Downgrade WiFi driver version:
 * Determine WiFi driver version installed:
 * gwmi Win32_PnPSignedDriver -Filter "DeviceClass = 'NET'" | ft DeviceName,DriverVersion
 * If version is 18.x, downgrade to version 17.x (Intel DLC):
 * Intel PROSet/Wireless WiFi Software Version 17.15.0.5 WHQL
