We've tested a couple of our links up to 3-4Mbps, but honestly we
haven't really tried to establish their max throughput. We know they're
2-3x what our backhaul is (1.5Mbps) and as we only have a small http
proxy cache and hence no other real source of higher bandwidth traffic,
we haven't put any energy into further measurement.
Our 802.11a links are also all < 2km, and most are <1km. FWIW, I recall
that once you get past 3km (?) on 802.11a you start to get protocol
timing issues. (Search for posts by jim at netgate dot com as he's posted about
this issue in various places recently - perhaps the seattlewireless
email list?). You can tweak the timing, but it takes a bit of digging
around and isn't available in vanilla m0n0wall.
Hope this helps. Good luck!
