I have a site that routinely degrades without reason. We initally thought it was interference, since changing channels temporarily fixed the problem, but we've not been able to find a source. It now appears that the simple act of restarting the AP was the actual fix, so it doesn't appear to be interference at all. I have a number of other sites, some of them in wireless range of this stie that do not appear to have any issues using the same setup and timing.
I began to suspect a timing issue and replaced the uGPS and timing cable, but no luck.
I'm currently running 14.2. As said, I have other sites on 14.2 with the same setup that do not appear to have any issue. I am upgrading to 15.0.1 as of this post to continue troubleshooting.
Failing that, my next step seems to be replacing the AP even though there are no indicators in the logs that the AP has any issues.
Has anyone seen this behavior?
