Default Wi-fi issue

Hi guys

I have got a problem with my wi-fi I think.

Facebook Twitter and most of apps are not working good for me. Facebook doesnt load the pictures and feed. Twitter has got the same issue.

I thought it was my house broadband but it is the same in my work as I have 16MB internet there.

They are working fine on 4G or 3G. Is there any solutions for that?
