RBS350 frequently turning magenta indicating no internet

Hi There,

I have a Orbi AX1800 WiFi 6 Dual-band Mesh Router (RBR350) mesh system comprised of one router (RBR 350) and one satellite (RBS 350). I ensured that all of them runs on latest firmware and I have a hardware warranty ti September 2024. For last couple of days, I am seeing that RBS 350 frequently turning magenta indicating no internet. However, devices connected to RBR 350 are working perfectly. How do I troubleshoot in this situation? Would adding one more satellite improve the situation?

Thanks for your help!
