Hi there,

What type building construction?

Metal etc.. and how far apart are the locations?

How far is the Wild-blue dish from the wild-blue modem?

What are the bandwidth requirements of your system—compared to Wildblue's capacity?

What model router are you using?

Depending the router set-up may be causing a bandwidth bleed out contributing to your "inadequate signal>

Slam Dunk cure is Ethernet or Fiber optic links rather than wireless.
