You need a router or a wireless router to do that.
If your cable modem is wireless you can set directly via wireless network a connection with your laptop (the laptop also need a wireless card (if dont have any built in))
The connection must be done in this way

ISP ----->> Cable Modem ---->> Wireless Router o Router ----->> Computer ( 1, 2, or more)

Can I use more than one modem on my phone line to support multiple computers? Also, where can I obtain a list of modems compatible with a Netopia 2249n? Thanks


Hello

The short answer is no you really cant use multiple modems. The internet should come in to your home via the modem, then go in to a ROUTER. Many times the router will have 3 to 5 ports on the back to hook your other computers too. This means running cables. Another way is to use WIRELESS cards that you can find on the net or from best buy.

If your router does not have any extra ports you need to buy something called and ethernet switch. Again they come in 4 and 8 port models up to LOTS AND LOTS Of ports for big companies. You hook the switch in to the router, then hook the computers in to the switch.

I hope this helps you

My linksys w/2phone ports cannot hook up with the ethernet


Most Cable Internet Service Providers (ISPs) use Media Access Control (MAC) Address authentication to establish Internet connection for end-users. MAC address is a unique identifier assigned to the network adapter/s of the computer.
To set up your Linksys router to work with a Cable ISP, you have to enable the MAC Clone feature of the router. MAC Cloning is a procedure which enables a router to copy the MAC address of the computer registered with the ISP.
To set up a Linksys router with Cable connection, you need to perform four steps using the computer that's been registered with the ISP:
i. Verifying Internet Connection
ii. Connecting the Devices Together
iii. Checking the Router's LEDs
iv. Setting Up a Linksys Router for Cable Internet Connection

Verifying Internet Connection
Connect the computer to the Broadband modem using an Ethernet cable without the router installed. If you cannot get online, contact your ISP. If it's online, use the computer to set up the router.
NOTE: Some cable modems use the USB port. If the physical connection is via USB port, you may not be able to go online via Ethernet connection. Contact your ISP to have the Ethernet port of the modem configured.

Connecting the Devices Together
After confirming the Internet connection through the modem, connect the modem to the Internet port of the router; connect the computer to any of the four Ethernet ports at the back of the router. For instructions, click here.
Checking the Router's LEDs
After connecting the devices together, check the lights on the front panel of the router. Ensure that the Internet light, as well as numbered light corresponding to the Ethernet port where the computer is connected, is lit. For further instructions, click here.
Setting Up a Linksys Router for Cable Internet Connection

Step 1:
Access the router's web-based setup page. For instructions, click here.

NOTE: If you are using a Mac computer to access the router's web-based setup page, click here.

Step 2:
On the Setup tab, click the MAC Address Clone sub-tab.

Step 3:
Select Enabled then click Clone My PC's MAC.

Step 4:
Click Save Settings.

Step 5:
Click the Status tab.

kb17251-004_en.png

Step 6:
Check the Internet IP Address. If the Internet IP Address has numbers, this means the router has been properly configured. You should now be able to access the Internet. If you're still unable to access the Internet, powercycle the modem, the router and then restart the computer.

kb17251-005_en.png

NOTE: If the IP address is still 0.0.0.0, click IP Address Release then, click IP Address Renew. If this does not change the IP Address, powercycle the modem, the router and then restart the computer.

I hooked up everything right modem to router, router to computer. but i still cant get internet to my computer. if i hook my modem directly to the compiter it works fine but not through the router


Some ISPs (Internet Service Providers) limit you to *ONE* unique computer connected through the cable-modem (or DSL-modem).
Turn the cable-modem off.
Turn the router off.
Connect the cable-modem to the router, via an Ethernet cable to the 'WAN' port on the router.
Turn the cable-modem on.
Turn the router on.
Connect, via an Ethernet cable, from one of the 'LAN' ports on the router to your computer.
Restart your computer.
You should be OK.
If not, telephone your ISP, and get them to trouble-shoot from "their" end towards your end.

I lost the disk for the RCA DCM425 digital cable modem the cable company gave me. how can i get the modem to work on my new computer?


Hello Friend,
If you didn't change anything in modem side, that means the modem is still connected to internet. in this case you can connect the modem to your computer via the Ethernet cable. with this cable you will not need to install anything on your computer, just plug the Ethernet cable to the RJ45 port and start browsing internet.
The only case when you will need the drivers is when you want to connect the modem to your PC via USB cable.
Here is a link where you can find everything about your modem: quick guide, user manual, usb drivers ...
Best Regards,

The modem will not connect to the internet via USB (only ethernet


It sounds like you need to download a driver for the modem's usb connectivity. You can do this by "googleing" the make & model from the manufacturer's website.

A router is basically a mini-computer that splits up one internet connections to 4 (or whatever # of ports you have).

Basic Connections to a router:
A Router requires a internet connections, so your broadband modem must connect to the WAN port (theres only one) of the router DIRECTLY. Then Ethernet cables go from the router to the computers on the LAN ports. Don't do something weird like connecting your internet to your computer then your computer to the routers WAN port, it'll most likely mess up.

Once you have connected your router like this, it should work.

If your modem only has a usb port, I have no idea how to make that work out. Sorry. Try getting a new modem from your ISP, or check if your modem does have a ethernet port, if it does just connnect that to the routers wan port.

Also computers should not interconnect with each other with use of a router. Thats what the router is for. Everything gets connected and split up at the router, nothing connects to anything else but the router, basically.

A stand alone wireless modem that connects into the LAN port (10BaseT connector) with a network cable or a USB cable to the computer's USB port.
and
A USB wireless device (similar in size as a USB memory stick)that connects into the computer's USB port.

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).

I can't get my computer on the internet . I am using windows xp and the modem will not get the internet on the dell computer


Hi, This modem can be used via one of two ports: ethernet port (network port) or USB port If your computer has an ethernet port, it is perferable that you connect through this as you will have better performance. If you don't then you can get an ethernet card installed inside the CPU. If it's not possible to connect via this connection and you have to use the USB, then you will need drivers. This website gives you full instructions on how to use this particular modem and also gives you the USB drivers if needed. http://www.triadtwcable.com/template_media/cablemodems/rca245.htm Good luck!
