"New" iPad - WiFi Issues

Hi.
I've had my new iPad for a little while now and at home it connected to our wifi with no problems. I am also able to connect to my dads mac and share the internet via that.
I went to my mothers and they have a new wireless modem/router which I was able to use for a day or two, but now when I try to connect to it in the settings menu it just has the little spinning symbol next to the network name (the tick doesn't appear) yet I have the wifi signal in the top bar next to the word iPad.
When I try to use the internet however it doesn't have a connection. My iPhone is connected to the same network and working perfectly, all settings are the same.

Anyone have this problem or know a possible solution?

Hi,
Lots of people seem to be having problems with wifi and the new ipad3, myself included. I checked it out in the iPad forum and got the following link. https://discussions.apple.com/thread/3812929?start=1020&tstart=0 I suggest you take a look and then speak to Apple and see what they say.
