About

• I faced bandwidth issues between a WG Peer and a WG server. Download bandwidth when downloading from WG Server to WG peer was reduced significantly and upload bandwidth was practically non existent.
• I found a few reddit posts that said that we need to choose the right MTU. So I wrote a script to find an optimal MTU.
• Ideally I would have liked to have run all possible MTU configurations for both WG Server and WG Peer but for simplicity I choose to fix the WG Server to the original 1420 MTU and tried all MTUs from 1280 to 1500 for the WG Peer.

Testing

• On WG server, I started an iperf3 server
• On WG peer, I wrote a script that does the following:
  • wg-quick down wg0
• Edit MTU in the /etc/wireguard/wg0.conf file

WSL2 with GUI using Xvnc

Note

If you want to use pure WSLg, you can try the new WSLg (XWayland) tutorial or the WSLg (Wayland) tutorial.

In this tutorial, we will setup GUI in WSL2, and access it using VNC. No additional software outside WSL (like VcXsrv) is required, except, of course, a VNC Viewer (RealVNC, TightVNC, TigerVNC, UVNC, etc, all of them might work flawlessly).

The key component we need to install is the desktop metapackage you want (GNOME, KDE, Xfce, Budgie, etc) and tigervnc-standalone-server.

For this setup, I will use Ubuntu (20.04, 22.04 and 24.04 are working), and install GNOME Desktop. Since the key components aren't bound to Ubuntu or GNOME, you can use your favorite distro and GUI. Check the [Sample
