The scenario is: two buildings with a distance of 800 meters one from the other.
At the moment there are two antenas on each building, with a wireless D-Link router on each site.
The communication between the two sites is ok however there are some moments (3,4 times a month) that the connection between the sites is dropped.
The reason of that is because the router buffers a lot and drops lots of packets. Each time I change the channel of the wireless it starts working ok
however when the router buffers a lot the problem occurs again.
Any recommendation of what to change in order to have a reliable connection between the two sites??
Thank you for your time
