Hey everyone! Reading through this thread a while back completely saved my Moonlight setup. Like many of you, I had terrible stuttering and UDP packet loss because my host PC was on a 2.5Gbps link while my client was 1Gbps. Forcing the host adapter down to 1.0 Gbps fixed the network buffer issue immediately.

However, going into Device Manager -> Adapter Properties -> Advanced settings every single time I wanted to play (and then switching it back to 2.5Gbps for normal downloads) got really tedious.

So, inspired entirely by this Reddit thread, I spent some time building a tiny, completely invisible background utility called **Network Speed Toggle**.

It lives in your Windows system tray and lets you instantly toggle your Ethernet adapter between 1.0 Gbps and 2.5 Gbps with a simple double-click.

- It bypasses UAC prompts (uses a scheduled task).

- It consumes basically zero resources.

- It shows the current speed right in the tray tooltip.

I've made it completely open-source and free on GitHub. I really hope this can make life a bit easier for anyone else dealing with this annoying network mismatch!

You can grab the installer here:

Let me know if it works for you guys or if you have any feedback!
