Laptop suddently stopped connecting to network

Hi,

Please can anyone help?

My new Inspiron N5010 (about 2 weeks old) has been working perfectly until yesterday, when it suddenly stopped connecting to my wireless network.

It recognises the network and attempts to connect automatically and fails every time. When I ran troubleshoot the message I got was "problem with wireless adapter or access point detected".

What does this mean?

I have run system restore to an earlier point when everything was working fine, but this did not help.

I know the network is ok because I have another laptop and a smartphone on the network.

Any advice will be greatly appreciated.

Thanks
