Need internet connection in two buildings.

Details:
1) HughesNet ISP - NO Hard wired connections available in this area
2) Two computers running Ubuntu
3) Current connection is in a metal shop with the HughesNet dish approx 5 feet from building. Cannot hard wire two modems to dish according to HughesNet. Anyone know if this is true or not?
4) Second computer is in residence approx 130 feet from shop.

I have a high powered wireless intercom (Dakota Alert) that works just fine from the house to the shop. It is supposed to have a 5 mile range, so my guess is that it isn't a standard intercom. Don't know if this means anything in regards to a wireless router signal.

Need the following:
1) Router suggestions
2) External, outside antenna, powered antenna or signal booster suggestions if it is necessary to get through all the metal and wood between the two computers.

Thanks,
Doug C.
