Constant random internet disconnection

So as of late, my internet connection on my laptop has been acting pretty strangely. It just randomly disconnects, sometimes the bars are still there, sometimes it shows the yellow triangle. In both cases my computer can't connect, while other computers still can connect the network and get the internet working.

It's starting to get pretty annoying, especially if I'm browsing, or playing a game.

If it's wireless then you might need a new router.

Well the thing is that other laptops work fine with my router. It's just the one I use that keeps randomly disconnecting.
