About a week ago I got some help with my home network with what I thought was a conflicting IP between the router and the modem. I reset to factory settings on the WRK45G (or 54G) router and reinstalled it and the Motorola Surfboard Modem that we have. Everything worked except one of the 3 laptops kept giving me a conflicting IP address. Somebody seems to have messed with a setting somewhere and got that laptop working but a few hours later our internet stopped working again, except this time even after power cycling I have "limited or no connectivity" even when plugged in directly to the modem via ethernet. Does anyone have any ideas/suggestions, I'm getting really fed up with this router/modem/comcast/whatever the problem is. Thanks, -Capn
power cycle again both the router & modem & remove the coax cable from modem for 10sec then reconnect & power up both devices.
