I have recently had problems with an intermittent cable connection that appeared to be caused by my own hardware. I am running Windows 7 Pro as my OS and it is completely up to date with patches. For networking I use a Linksys EA4500 dual band N router and a Motorola SB6121 DOCSIS 3 cable modem that is brand new out of the box three days ago. My router is relatively new as I only bought it about 6 months ago. After hooking up the new modem I had a repeat of the intermittent signal problem so I started to do more research on networking basics and now I have run into something I'm unsure of and need help. My network connection on the front end is a little bit odd because I use Vonage for my phone system and it has its own cable modem(?) inserted between my modem and my router. What I have discovered is that while my modem is qualified as 1000Base T compatible, my Vonage box is only 100Base T qualified. The question for you is, could having the 100Base T Vonage box between the 1000Base T modem and the 1000Base T router cause any degradation in transmission speed over the LAN? Any information to clarify this for me will be greatly appreciated.
