We are in the process of beta testing our system with 4x 450ms using cbrs and had great success with the tower staying up and clients were happy with speeds/connectivity. Just recently the sms started dropping daily and only the ap with two clients drops. The device log shows high crc issues so we replaced cable ends even though all tested “pass”. We’ve put in several tickets with cambium support and we’re told it could be our sfp connection and it is “port flapping” or it could be our switch. So, we replaced our cambium switch with a unifi gateway and now in the process of getting our aps back online and keeping them online. Any advice or feedback will be greatly appreciated and I will answer any questions or specifics with haste. I’m sure its something simple to get this fixed but keep coming up short with a solution.
Is the port on your switch this AP is plugged in to flapping or are the customer SMs dropping and re-registering to the AP? Your post seems to imply both things are happening maybe? If so, the two issues are unrelated.
Testing cables is simple and necessary. I don’t personally like the Cambium switches at all, but they do provide better diagnostic data than anything unifi switches will. The cambium switches do provide basic cable testing. How do you have these APs connected to your switch? Fiber SFP or copper? I’m guessing copper based on your post.
