Hi @Shujaa_Ahmed_Issa ,

Could you please clarify what you mean by link instability? For example, are you experiencing higher latency, reduced throughput, or devices disconnecting for some reason?

I would recommend that you raise a support ticket. One of our engineers will assist you in isolating and resolving the issue.
