Well here are the Specs of this modem I currently have. Found that out when I put a Linksys one on it and returned the second one of the old Ambit, I like this newer Ambit and recommend it because other wise your MAC might be an unautherised one. I did connect to this on my old modem with all the problems but now I connect to the server in St. See the server is just up the road from where I live. If only I would connect to the server that I am supposed to I would get unbelievable speeds. It is actually decent and gives me what I should get in my bedroom and has even greater speeds in my computer room(the one that is a dedicated line for internet). On my second return of that modem, I got the new model from Ambit. I kept asking for a SurfBoard Modem but they no longer carried them in my area, but my cousin got one in his area(trust me, should all be one area since Charter has a monopoly on the St, Louis area for cable providers but it isnt). I told Charter about this problem and they said that it was nothing. I would test as getting the speeds I was suppose to, but it would not transmit between the PC and cable modem like it should. With both USB and Ethernet ports enabled on the Cable Modem, installers have the flexibility of what port to use. The U10C018 supports DOCSIS 2.0 specifications including A-TDMA/S-CDMA.

The first model that is now no longer made and sucked. The Ubee U10C018 Cable Modem comes in a compact design, measuring in at under 5 inches long. I have had both models that Charter has provided to thier customers. Around my area and probly others, you see commercials for Charter High Speed Internet and the people are using a flat, grey modem.
