I know in some literature they talked of Ruckus being self-healing. You can't be if you manually are setting power. Manual power setting is fine for any initial design but if you get an unknown interference or want to introduce a new AP, or one drops off you have to manually set power on all the neighbors. The controller should be able to see neighbor signal strengths and then should be able to determine if an AP should be set to lower or higher power based on these measurements.
An enterprise controller, (small to medium sized) which this is billed as should be able to do this. Without this I've negated half of the reasons for having a controller. I agee a site survey and manual plan could help short term. What I don't understand is why the system worked well for 2 years on auto power, then goes belly up. 3 of the 4 building are basically identical to their old config. That implies change. Theirs or mine. I've done a bunch to try and eliminate me, which leaves the controller doing something different in the updates. Manual config would be stop gap, until I could replace this system. I wasn't planning to replace it after 3 years but if it can't perform the duties expected of it, then replacement with a real enterprise grade solution, it may need.
