I have a WRT54G2 wireless router. I added a WI-FI range extender which connects to my current network, and then should re-broadcast my wireless communications.I can connect with this new range extender to my current network, it generates new security...

I have a WRT54G, is there any way for me to attach a hi-gain attenna? The router is very basic and does not show any external connectors. Is there an internal connection?
