OT: Wireless router

[Leslie Jensen]

Hello list.

Excuse me for the of topic subject but I wonder if anyone here can 
suggest or help me with a solution to the following scenario.

I need an of the shelf Wifi-router with the following capability.

It should provide at least two separate Wifi networks. One private and 
one guest network. The guest network should be time controlled so that 
it will turn on and of on the times set.

Is such a product available?

Thanks :-)
