Slow Internet While connected via GVC and Nextentender

I am noticing this behavior in most of the users that use GVC and Nextender. While connected internet speed dramatically decreasing (app. by 90%). And I am using Split tunnels in the VPN settings. One more thing I noticed recently even when disconnected from Netextender, internet was slow until the application is totally closed. It works fine while configuring the VPN manually using Mobile app downloaded from Microsoft store.

We had some simliar issue with Win 10 1803,1809,1903 on some PCs with the upgrade to 1909 or 20H2 and an update of the LAN/WiFi drivers this issue was solved.
What version of NetExtender / GlobalVPN client are you using? Have you tried other versions along with Chojin's suggestions?
I have tried with latest versions of Netextender and GVC and the windows version 2004 and 20H2. I have to check with other users if it's the case with the drivers.
Hi @msmfarhan,
The above subjected issue due to the Windows 10 and the wireless adapter.The solution is to disable Receive Segment Coalescing on the wireless adapter. Microsoft actually provides an automated fix as a download.
Details can be found at the following Microsoft Answers link:
This solution works fine.
Thanks
I have the same issue with an Ethernet connection. The fix appears to work with wifi, but not an ethernet connection. It is not related to the sonicwall settings, as my speed is very fast before the global connect VPN client is started (450-500mbs) As soon as I open global connect VPN client (and before I connect to the VPN) speed drops to 80mbs.
Additional information - this does NOT happen with netextender, only GVC. If I use my laptop on wifi, the slowdown does not occur (after I use the automated fix from Microsoft)
