Trouble with Internet access

Hello, 

I have a Dell Inpriron R15 5521. Recently it has some problem with wireless. When I turn on the laptop, it does not recognize the wireless after about 10 minutes. Sometimes it says that wireless is connected but I can't browsing web or update my antivirus program. Plz help me, because I need to do so many homework online, but with this situation, I really worry. Thank you.

Here is my ipconfig
