Need WLAN Advice! Huge Headache!

I have taken on a Wireless Networking Project that is getting the best of me. I am looking for some advice on how to create a WLAN for several cabins at a Fly Fishing Lodge in Montana.


Here is what I need to accomplish:


The Lodge has 10 physical buildings.

1 - Office with Pro Shop

1 - Kitchen building with Dining area (20 feet from office)

1 - Lodge Building for cocktails (60 feet from office)

7 - Cabins (100 feet apart from each other and Cabin one is 40 feet from the Lodge building)



The Office has a one DSL line coming into the building. I'm using a Linksys WRT54GS Router off the DSL modem to provide an Ethernet connection to one Desktop Computer and a wireless connection to an additional Desktop Computer in another room in the office. I am trying to provide additional wireless internet connection for my clients in each of the cabins and the Lodge Building without running cables.


Here is what I have tried:

I had heard great things about the Linksys WRE54G Range Expanders and was hoping to just chain them along to all 8 buildings. I originally bought 2 WRE54G Range Expanders since they are 'Marketed' as providing 300 yards of coverage. I placed the first Range Expander in the Lodge and thought I could place the second one in Cabin four. However, each cabin has metal roofs so the signal was too weak. I then bought 6 more WRE54G Range Expanders with the hopes of placing one in each cabin. After a NIGHTMARE experience with Linksys support and several wasted weekends I came to the realization that this isn't going to work. At first I purchased 8 'Version 1' models of the WRE54G Expanders and was unable to get them configured. I then (per Linksys advice) sent them all back for 8 new 'Version 2' models which have an Ethernet port on them for easy configuration directly from the Router. I was able to configure all 8 WRE's and started placing them in their locations. After I got past Cabin one, I could no longer receive an Internet feed. As it turns out, the signal was being so chopped up as it went through each WRE54G Range Expander that after two buildings there was nothing left. Of course Linksys never mentioned my design was flawed from the outset after LONG hours/days on the phone with Tech support.

Outside of digging trenches through the property and affixing Access Points into each building, are there any other solutions available without having to use any wiring?

Any and all advice is greatly appreciated!!!

Thanks!
