I have an issue I suspect is related to possible interference but can't conclusively prove it. What I have are six radio's mounted on a tower all using completely different frequencies but 2 seem to sporadically and drastically reduce throughput and are pointed in generally the same direction (maybe 10 degrees separation in paths) . What I'd like to try is to implement some type of script or rule set that basically says "Use IP address "A" as the primary gateway , and if throughput falls below X level by this link , use alternate gateway "B" , when throughput through "A" returns to normal , resort back to "A" path. Is this doable ? I'm a complete noob at scripting so any help would be appreciated.
