I'm curious if anyone else is seeing what seems to be a high failure rate on the 450M APs? We've been deploying sites since last fall and have had 1 AP sent back for repair and returned, 1 is being repaired right now, I just submitted for another one to be repaired and today my techs are going out in the field to replace one we think is failing. We have about 40 deployed, so we are near 10% failure rate.
All seem to be showing the same symptoms of just not being able to stay up, they will go down and we can bring them back up by power cycling through the CMM, but it becomes an issue when an AP needs manual intervention to stay active. Each time a new radio goes up all cabling is tested and after testing good it seems to support the new APs just fine, so I don't think it is anything on our install/plant that is causing an issue.
Cambium has been easy to work with for sending back for repairs, so I'm not complaining there, though I'm not sure if I ever heard what the issue truly is. Curious if anyone has any feedback to add to this.
