I'm having problems getting my home network to work smoothly. I believe it is in the communication between router and cable modem. I think these problems all started when Comcast implemented Bridging in the modem(im not positive). Not sure if this is IP address related , MAC address related or another problem. What I do know is that..... A. Sometimes even the wired connection to router goes out and can require some or all of following. Restart Modem, Restart Router. Restart Computer and/or "repairing" network connection. B. Wireless connection..Wireless Networks can be "seen", but cannot get an IP Address when "repairing" or connecting. Any type of Description to how routers/computer/modem interact would also be appreciated.
