How to write a script that will turn restart my internet connection if its weak?

Question

I am living in a guest house and my landlord is kindly letting me use his WiFi, however, my connection strength constantly toggles from good (5 bars) to bad (2 bars). Additionally, it seems that my browser freezes whenever it reaches 2 bars two, which is really weird (or maybe a weirder coincidence) and the only way to unfreeze it is by disconnecting my connection on my laptop and reconnecting again.

I know this may not be the best or permanent fix, but just out of curiosity, is there a way to write a script that will automatically toggle my connection off and on if my WiFi connection becomes weak? If so, how can I do this?

If it matters, my OS is Windows 8.1.

I found a nice batch script to automatically repair LAN connection on the net so, i share it with you, and hope that can help you !
