I have an iPad 2 (none 3G) I have just updated the software and now whenever I unlock it I have to re connect to my home wifi network, could anyone please help?
thanks in advance

Try forgetting the network and connecting to it again. That sorted it on mine, was having the same issue on both my iPad and iPhone.

And reboot it too.

*Edit - both your router and iPad.
