My Ruckus ICX7150-C12P has never worked properly. Switch stuck in router mode, confirmed Switch listed as router on ISP device table. Unable to Telent to flash image. Problem confirmed to be hardware. Problem has existed since new as unstable. Fiber WiFi provider checked everything and replaced modem as we thought that was the issue. Everything works up to the modem. Bypassing Ruckus (disconnecting from modem)results in stable wifi. Reconnect Ruckus with hard CAT line starts with excellent speed download/upload but 5 seconds later, all gone. Zero download/upload. Does not change after that. IT specialist (hired by me) worked 3 hours and confirmed problem. He states Ruckus has a hardware problem, not a software or connection problem. He advised the unit needs to be replaced and is a common problem with this unit
