Can't download apps ! AppStore PROBLEM ???

I can't download apps on my iphone 5s. I have a proper Wi-Fi connection but I am not able to download apps. The icons of the apps appear on my iphone's homescreen but they do not download (they remain in "Waiting...") and even if they do start downloading the speed is very slow. I tried downloading from the Itunes but the same result -- the apps download very slowly. The sites on both PC and iphone load normally. My download speed is around 15 MB per sec and my upload is 6 MB per sec. What can I do? I did a reset on my router, I have removed the wi fi password, I even did a full reset on my iphone.

Can you guys please help me.

Please help.

Thanks!

I didn't find the right solution from the Internet.
