why wont my samsung galaxy tab 2 let me use the internet anymore?

never had any problems with my tablet and connecting it to my wifi. but for some reason whenever I try use the internet i.e youtube it say 'please check your network connection'. not sure if my daughter has accidently changed something on setting but I have had a look and nothing has stood out to me. wifi is working fine on other devices aswell. please help?!?
