Connecting to a web page? should be simple

HI All

I am trying to connect to a relay board that can be controled via opening a web page. It requires username and passwork as part of the URL. I have tried lots of things and read as much as I can online but still not working. The following code worked from a computer and my phone, I don't need any information back from the page either. Any help much apreciated thanks.

client.connect("admin:dinn@192.168.1.100/SetIO?p63=1", 80);

You should read the "Client side" section here.

It isn't too difficult. You must send that "Authorization: Basic" parameter to the server with your user:password base64 encoded.

client.println("GET /mypage.php HTTP/1.0");
client.println("Authorization: Basic yourBase64stuff");
// rest of your header stuff
