Ruckus ICX 7150 C12P switch Issue

[Sasikumarb78]

My home comes with Ruckus ICX 7150 C12P switch installed. When I hook up my TV and VoIP phone through a hardwired ethernet cable from the switch. The stream in is very slow and good see the latency in the TV and my VoIP phone doesn't work. But, I hook up my TV and VoIP phone through a hardwired ethernet cable from the router. The stream in and the phone works fine.

Need to talk to the Ruckus team to troubleshoot the problem.
