Eric> Make sure that you update the MAC address with charter, and that Eric> they actually update it. I've had a few problems where they Eric> haven't even though they said they did. Just to chime in here, Charter seems to have a new automated system for checking internet problems. I bricked my WNDR3700v2 recently while trying to upgrade it to a newer version of DD-WRT, so I had to fall back quickly to my PCengines (http://pcengines.ch) based m0n0wall box to get the internet working. Since I munged the wrong MAC address into the m0n0wall, I sighed and called up charter. The automated system was quite nice, and did a full remote reset of my router and presto, things started working again. Eric> Also, a lot of modems have diagnostic suites built in. An easy Eric> enough way to get at it is to turn it off, and unscrew the coax Eric> line. Now boot it up, and it won't get an IP from charter, but Eric> it should give your router an ip like 193.168.100.100, and the Eric> gateway should he something like 192.168.100.1 (check for Eric> specifics) but that gateway is your modem. Punch that IP into a Eric> browser and see what comes up, usually the password is something Eric> stupid, and a Google search will yield it if its not admin. Keep Eric> in mind you pulled the cable, so it will show that. This will Eric> also work when you have no internet, and it usually shortens Eric> phone calls with Charter. I've got an old Motorola Surfboard 3100 I could give, my current 5120 is working just fine. John
