You could also dedicate to the Pronto a router with WEP and have another WAP router for the rest of your home network to increase your security.

1) Connect one of the WPA router’s LAN ports to the Internet or WAN port on the WEP router. This allows both routers to share the same internet connection.

2) The WAN port on the WEP router should have a unique IP address on the home network’s subnet.

3) One port on the WEP router should be port forwarded to allow access on the home network only via this port.

4) Close all other ports on the WEP router as the Pronto will not need to use them. Normally, this is done by default on most routers. By doing this, the WEP router is made as secure as it can possibly be, by only allowing data to flow in and out of one port onto the home network.
