Problem with wireless router

[macypro]

So, the ruter is D-link DL 524, i connected it with my modem for DSL and wireless network works great!

I have the problem with the phone (Nokia C3) it cant open streaming (youtube etc..) but it doesnt metter the problem isnt on the phone because when i connect on someone else wireless network youtube works. On my pc everything works yt etc... So the problem must be with the router...

Can anyone help me with this please ?
