WiFi
Vauxhall Road Connection
We (Milan and Aran) have a wireless connection between our flats which are about 250m apart. We used ESR1221 200mW access points, 14dBi backfire antennas and 5m low-loss coax cable on each end and configured them as a Wireless Distribution System which allows them to connect to form a single local network. We don't have perfect line of site as there is a couple of brick walls and tree foliage the signal needs to pass through, but our hardware seems to connect quite well regardless - apparently it should connect over 2km line of sight, or 5km with the 600mW access points.
Issues
The network access from my end (Aran, the remote end) failed today (01:17, 18 April 2009 (UTC)) and it turned out to be due to Milan initiating a large file transfer from his computer onto the NAS. This was the case even though the access point, computer and NAS in question were all connected to a switch not a hub. Milan solved this by upgrading it to a gigabit switch, but this would need to be solved a better way if we had a lot of gigabit LAN activity.
