I would like to set the CC modem/router to bridge mode and understand only someone at Comcast can do that. However, I called and was told that CC cannot do that, and to just connect my other router to the back of the CC unit!!!
ComcastLarry placed my new SMC in bridge mode. I send a private message [PM] through this forum to him and he enabled it within a couple hours. The WiFi signal on the SMCD3GNV is awful. Bridge mode enabled me to connect my Cisco E3000 router and my wireless signal is much better. Phone still works too. bridging does not disable the digital phone service. Thank you ComcastLarry1.
