Hi,
We've worked in relative 5GHz isolation for the past few years by using channels the FCC originally designated unavailable for most wireless APs. Even after they were made available for use, most wireless APs weren't updated to actually enable their use.
Yesterday, I noticed an AP using the channel our AP was set to, 100 - 5.5GHz. I switched to 132 - 5.66GHz just for my own sanity and went on with my day. Fast forward to today and I noticed the other box had jumped to 132. I thought maybe the admin of that box had done this manually, but after switching again to 100, I saw the other box followed after only a few minutes. Repeated again to be sure, and sure enough the same thing happened.
I'm not questioning the performance implications of sharing a channel, I realize it's not a big performance hit to share spectrum. What I'm curious about is the question of my post topic - why might this AP be programmed to jump to a channel already in use instead of one not being used? As a software engineer, I'm thinking it's poorly written code that just happens to result in this scenario playing out. However, a wireless engineer may recognize a reason behind this.. I'm just curious.
Any ideas?
(p.s. - If this looks similar.. the last post was removed for drifting too close to home networking territory. As this is a conceptual question relating to fundamental concepts of wireless networking, I know it was a moderation oversight. I've rephrased a few things to make it clearer. Thank you!)
