No Internet Connection - Norton Free Trial Expired?

[Simon Mulligan]

Hi,

My new laptop's (it's a HP Pentium 2261a) free Norton anti-virus trial expired today. I had been planning on using another free ant-virus as soon as it had expired rather than purcase Norton. Now I can't purchase Nortonanyway, as I can't get online.

But just after it expired earlier today, my Internet connection has stopped working. I can get on to Facebook, Twitter and my Gmail inbox for some reason, but everyting else just will not load (it just says e.g. 'Waiting for Google.com as if it is loading up but it never does).

I diagnosed connection problems and it said DNS Server isn't responding. My old laptop works fine with the same wireless modem so I know it can't be that.

Anyone know what I can/should do on the new laptop?
Any help would be much appreciated.

Many thanks.
