A quick blog for archiving purposes. Since my upgrade to Windows 10 Creators Update last week I had been experiencing very slow wireless performance at work. At home or while tethering everything was as normal.

For me the solution as to disable “Receive Segment Coalescing” (RSC), described as ‘workaround #1’ in this post:

Steps:

• Run an elevated PowerShell prompt
• Get-NetAdapterRsc to show the status per adapter
• Disable-NetAdapterRsc –Name "your_wifi_adapter_name" to disable

Immediate fix for me!

Thanks Tripp Parks [MSFT] for the workaround!
