Problem 9x Unleashed APs (T300 and T301s) on a big parking area. 2x of them are Root-APs. 7x are Mesh-APs. No Wireless Clients. Only IP-Cameras connected per Cable with the Mesh-APs. Issue: Network unstable.
What i have done with Ruckus Support Contacted Ruckus Support about 6 Month ago. Support first thought it is because the Mesh-APs are jumping between the Root-APs. Suggestion: Set a fix Mesh-Uplink-Route. Before doing so i decided to disconnect one Root-AP. So no hopping between Root-APs possible anymore. This did not solve my issue. We discarded this Suggestion. After that Support checked the Logs and thought is must be a firmware bug. Because the Network was unstable it was hard for us to do an Update. But after restarting the Root-APs the Network was suddenly stable (Ping stable at 1 - 2 ms) for one whole week and we deciced to do the Update. So we updated from 200.1 to 200.3. But Problem was back again. After that Support checked the Logs again and told me there are Interference within the 5GHz Band. I should do a Site Survey. Case closed. No Support.
What i have done by myself After that i tried to investigate this a little bit further by myself. Because the Installation Site is about 800km away from me and the APs are mounted about 10m high it's not that easy to try something. Because the Network was stable about one Week after restarting the both Root-APs i did not believe in any Interference within the 5GHz Band. So i restarted my Root-APs again and since that the Network is stable again.
Where is the Difference? I am not sure where the Problem is. This is because i need your help and experience. After restarting the Root-APs the Master Role changed for a short period of time but at the end the Master was the same AP again. So it did not play a role which AP the Master is. But when the Network was unstable there where 5 Mesh-APs connected with the Master-Root-AP and only 2 Mesh-APs with the Standby-Master. After restarting it is exactly vice versa. Maybe it is a load issue (CPU/RAM) or in the end a (till now) unkown Firmware-Issue?
What do you think? Is there something i can try to find the Root-Cause? Any Suggestions welcome.
Sorry. Unstable means that i have a poor Ping Response Time (>400ms) which also differs much. Also my Mesh APs are going offline and did not response to a Ping (Timeout). Timeout also differs. Sometimes its only 3 Pings which get lost. Sometimes the Mesh-AP is not reachable for multible Minutes. Within my Unleashed GUI i am getting a lot of Heartbeat loss.
Marco, are the root APs changing channels? I am not familiar with unleashed but on our mesh networks connected to a Ruckus ZD, we use a command through the CLI to disable channel fly after 60 minutes of uptime. If the root AP detects interference and changes channels, the mesh APs drop and reconnect. Also, what kind of switches are you connected to?
