I have a modem arris cm450b, i bought splitter to use 2 cables but the the cable connected to my sons computr isn't working

That is not the right way to do it. Connect one computer to the cable modem using an USB A/B cable from the USB port on the modem to an available USB port on the computer and connect the second computer to the modem Ethernet port-to-Ethernet port using an Ethernet cable (probably the modem came with one Ethernet cable).

Hope this helps.

Moderm speed

Your question is garbled but I'll try to explain some of it.

Your ethernet LAN jack on your computer is probably 100mbps and the ethernet LAN jack on the modem is also 100mbps, connect them together and it will tell you that it is connected at 100mbps because they are both working at the same speed.

As for the other connections, you are mixing usb and ethernet up so much that I can not tell from what you are connecting together.

Can the modem's ethernet port connect to a video game console?

Most modems that have both usb & ethernet connectors are either/or, not both. I recommend using
the ethernet connection to your computer than the usb - the ethernet connection is faster & more
reliable. It also frees up your usb port for other use. If you want both your computer & game console on
the internet, then you need to buy a router which will allow you to share the modem.

I want to change usb to ethernet interface. When I try to do it is failing to communicate with the modem

Whenever you swap the Ethernet and USB connections, it will fail to work as the modem is still configured with your computers IP address on the port you are changing FROM. Since the computer has not used the Ethernet port after being changed from the USB port, the modem has no IP assigned.

The solution is simple and must be done ANY time ports are changed, either ones on the modem, or if you were to change Ethernet ports on you computer.

Swap your connections, then reset the modem by unplugging it's power cord on the back for at least 10 seconds, then plug in.

This forces the modem to reconfigure it's ports, and to re-issue the IP address to your computer on the new port.

Since the modem only configures a port when the computer is plugged into it as it starts up, the other one is left in an unusable state.

The same equally applies if you were to add a second computer using the second modem port. You would also need to reboot the modem. Note that using both ports on the modem, each of which gets a separate IP from the ISP, is usually disabled by your cable company as you normally have to pay extra for multiple IP addresses. Sometimes the ISP overlooks this and you can get away with a free second IP address as I did with this same modem... until they wised up! Now I can use either port, but not both together. Only one get's an IP address.

Ethernet cable does not fit

The modem jack is too small because it is for a phone line connection not an ethernet connection. If you want to get online by dial-up, you need to connect modem to a phone line. Ohterwise look for another input jack on the laptop that the ethernet cable will insert to.

OK. First of all you do not need a special or seperate driver for the Ethernet port. Its factory loaded with your OS.

All you need to do is plug the Ethernet cable into the LAN port on your HP Desktop and then into the LAN port (not the WAN port) of your cable modem.

The second thing is if its only a cable modem, then I suggest you proceed with caution as there is NO built-in firewall on a cable modem. Yes you will get on the net, but you are likely to be attacked with virus the moment you connect. I suggest you check very carefully whether the cable modem (if that's what it is) does/does not have a firewall as you would be very unwise connecting up like that.

Next, forget USB connection to the router/cable modem. That technolgy we've moved on from.. Your Vista shodul be 'plug n play' adn should configure the router for you. obviously that bit isn't so slick on yours.

Let me know how you get on..

Ethernet vs. usb

FYI for those people trying to use a ethernet and usb cable from a cable modem - it may work for a while but it won't work forever - your ISP will only allow one IP address out of the modem unless you pay for additional addresses (then you need a switch). Each device you have on the modem is fighting for that IP and eventually it will just quit working (if it works at all).

If you want more than one computer on your network (on the Internet or sharing printers/files, etc) then you need a router or a gateway (cable modem/router combo which I DON'T recommend).
