i use to use Hawking's high gain antenna... it helps a little... but not that much.

as for connecting 2 keyclones across a wireless motel network.. not much i can do there, sorry. i'd say you are lucky it ever worked. try setting up a web server on one of your machines and try to hit it from the other. see if that works at all. if not, then the motel has changed their setup and isn't routing data between peers in house.

one solution could be to use a local hub and one of the machines as a gateway to the network.

the other would be a udp proxy, but keyclone doesn't currently support such a setup
