I am trying to install the SPA9000 with an SPA400 unit. I have 2 phones 1xSPA962 and 1xSPA942. I am running a mac with virtual PC ruinning XP. The setup wizard is not recognizing either the SPA9000 or the SPA400 on the network. I have an RVL200 Linksys router and an SRW208P Switch. Also, the setup wizard is telling me that I need to upgrade my firmware but when I try it is not allowing me to. Can someone please help?
