Lag using Dell Latitude E7240

[Guest]

I received a laptop from my school, it's good. When I connect to my house wifi, it runs fast and smooth. At random points, my facebook would stop working saying 'No data received'. This isn't just for facebook, all websites. I also played League of Legends, disconnected 4 times towards 30 mins of the game. Had to turn on airplane mode (using the switch on the side of my laptop) and turn it back off. When I start loosing connection, I am still connect to the wifi. My house has around 4+ laptop that work perfectly fine, none of the laptops has this problem.

Take it back to school and get them to replace it.
