We are moving to a rural property and will be putting the office in a separate building about 100 yards from the main house and DSL modem. We need to keep both office and home on the same wireless/wired network and want keep up the internal network speed for large file transfers. What are the pros and cons of going with a wireless bridge between the two buildings (a pair of EnGenius ENS200s of ENS500s look like they would work) versus a range extender and access point (Amped has an AP600EX access point + SR600EX range extender) that could work)? The sight line between the buildings is spotty with some large oak trees in the way, but there are a few patches of wall that would be unobstructed. Better still would be to mount units indoors and not have to worry about sealing cable holes. It would be nice to have wifi coverage across the entire 20 acres, but not sure how practical that would be. The good news is that there are no competing wifi networks that I've been able to find wandering the property with laptop in hand. I'm new at building a network beyond the confines of a 1000 sf city house, so all suggestions and warnings are welcome!
