Cannot connect to wireless home network any more with laptop

Hi all

I have a toshiba windows 7 Laptop, and its always been connected to my Virgin Internet wirelessly for bout 2 years. However now when i switch the laptop on, it does not connect to the wireless internet anymore. My network comes up in the wireless network connections box but as soon as i click on it it pops straight up and says windows was unable to connect to xxxxx etc.

I have tried turning of router etc for 10 seconds and plugging it back in but nothing. i have checked my wireless adapter card for drivers and it says i have latest drivers.

Everything else in the house, ie phones, playstation etc connects to the network fine, and when i hard wire my laptop to the router again it works fine (am using laptop now to type this)

So i am at a loss....

Anyone any ideas?

Thanks all

Chris

I personally would first check drivers for updates and make sure they're all working correctly.

You could also completely remove the wireless configuration that you have for the access point. Then re-add it.

If that doesn't fix the problem I would try a system restore if it was available.
