Try the following to start:

When your laptop connects to the other network, disconnect from it. Depending on your OS, your laptop will not reconnect automatically to that network.

Also, you can change the order of the networks, putting your Wifi at the top of the connection preference list.

You also can change the roaming tendency of your wifi adapter in its property settings. Changing it to "conservative" will stop your laptop from wanting to switch.
