Minecraft kicking me from the Internet?

I have a new laptop that I just installed Minecraft in. I usually play on a desktop with a wired connection, and never get disconnected. Today, with Wi-Fi connection (Excellent signal), I keep constantly getting disconnected when playing 3 minutes or less on a Minecraft server. When I'm just on the internet, this doesn't happen. I looked and saw that port forwarding could be the issue. Maybe I forwarded wrong?

It started letting me play on Minecraft for minutes each time I disconnected/reconnected, but it's now down to 1-2 minutes.

If anyone can help, that would be amazing. Here's a picture of my port forwarding:

You may have not port-forwarded correctly.

Try checking if your "Internal IP Address" is correct.
If you're on Windows, of course. I do not know for any other platforms.
1. Run "cmd.exe"
2. Type in "ipconfig" and press Enter.
3. Find the "IPv4" Address and use that as an "Internal IP Address" in your port-forwarding.

But if it is correct, I do not know what is the problem, sorry.
