This is my school laptop that I take from Four to Five different places everyday to do work and such. Ive been having trouble with the WiFi on my laptop. When I first received it everything seemed to work great. Then as I connected to WiFi one day it would not let me connect to websites. I tried Re-Joining the network and hitting the little switch to the right of my computer that disables and enables WiFi. This problem happens anytime I leave my computer on when switching networks or if it runs out of battery, it will do the same thing when I start it up. This forces me to restart my computer any time I move from place to place. Are there any solutions to this or is it my WiFi going bad?

It started this one day after turning it on. I don't remember changing any settings.
