Household Range Extender

Do you supply a wireless range extender for the R201P. My house is quite large

I don't believe there's an extender for the 200 series. If you have a large house and you need to extend one hop, you should look into the mesh features in the E400/E500.

The R200/201 can be configured to run as a repeater. You can have one unit working as a normal AP. On the second one, under Wireless->Basic->Wireless Connection Mode, select 'Repeater'. 

As mentioned above R200/201 can be used as range extender/repeater .

please check this post on configuration and other help .
