USB and Ethernet on Cable Modem

[stokeybo17]

I recently bought a lynksys wireless router, which i have used before and installed with no problems (on another computer) and need help getting a setup correct

The computer in question is setup as follows : Windows XP SP2, Scientific-Atlanta Cable Modem, Comcast Cable service

The cable modem is currently connected to the PC via USB. There problems with the network card(?) and the modem wouldnt connect with an ethernet connection. I've been off at school (this computer is at home) and have ignored this for a while. However, I am wishing to setup the wireless router at home, temporarily.

The router has no USB ports, and before, I have successfully connect both my laptop and the desktop using the same modem, one with USB and the other ethernet, but for some reason I cannot seem to get it to work tonight.

To sum it up, my question is this: is there a way for me to network the router so that the modem can still be connected to the desktop with USB?

No, you can not use the USB and Ethernet interfaces at the same time.

What did you do to connect the computer to the cable modem? Be sure to reset the modem after you connect it since the modem temporarily binds to MAC addresses.

AA, what you said is usually true for cable modems, but it looks like the SciAm modems support connecting with both using USB and ethernet at the same time.

2. Connect your PC to either the ETHERNET port or the USB port using the
appropriate data cable. Do not connect your PC to both the Ethernet and
USB ports at the same time. You can connect two separate PCs to the
gateway cable modem at the same time by connecting one PC to the
Ethernet port and one PC to the USB port.

stokeybo17, if you post back the info suggested in this post (http://www.cybertechhelp.com/forums/showthread.php?t=84447) for both computers while connected to the modem, we may be able to figure out what is wrong.

You may run into problems with comcast though if you connect like this for extended periods of time. Most likely, if this is just a consumer account and not a business account, you are only allowed 1 IP. In this setup, each computer would pull a unique one from comcast. If there techs pick up on it they may tell you that you need to change your setup or they will shutdown the service.
