Problems with Router settings (novice) – PC for All

Hello

I’ve just bought a new laptop which I so far am very pleased with.

The problem is that when I connect it to my router (D-Link Dir605L) stops Internet on my iPad to work. I can still find and connect to the network but gets no internet.

Internet connected both my iPhone and my new laptop still works.

Have had similar problems with my Xbox past but have seen to play Xbox when no one else is using the Internet.

Have tried to change a variety of things in the router settings but are not completely familiar with it.

Anyone have a clue how I solve this?

Thanks for your time!

Best wishes
