Hi, I have mac book pro and I have issues with my internet. I was hoping that upgrading from Yosemite to El Capitan will solve it but it didn't. Basically my internet is really slow. When I use the same network on my iphone and ipad it works well but on mac book it is horrible. I cannot load pages, Skype conversations are cut off, I cannot even use camera, etc. so can someone please help me? Many thanks!
