Cable Modem and LAN

Recommended Posts

I have a cable modem connection at my home. Before i got this connection i had made up a LAN setup connecting all 3 computers of my home making a network. The cable connection i got came with a cable modem which is connected to my computer with a USB. It also has a option to connect to my LAN card but i used the usb port. Now the problem is that i cant run both my networks together. I want that home network to work along with this cable connection. If both connections are enabled, the home LAN is working and file sharing is possible, but the cable doesnt gimme the internet then. I dunno any settings for internet explorer, it works on automatically detect settings. To use the internet i have to disable my home lan. can any one please tell me what to do so that i can run both connections at the same time?

You can have multiple connections, but unless you bind a service to an IP it will try and use all of them. Hence, my machine has 10.0.3.10 for internet connections, 192.168.0.10 for talking to my laptop and 192.168.1.2 for talking to my phone. Things that I want to use online have to be bound to 10.0.3.10, as that is the only connection that routes out of the  house.

If you are using a router to connect your 3 computer together all you need to do is connect the cable modem to the router.  Otherwise you need to set TCP/IP information for the LAN connection manually, and leave out a Gateway and DNS.  This way whenever you need to connect to the internet it will use the cable modem.

I tried this setup... i setup both my LAN and cable modem. LAN became Local area connection, and cable modem got the connection local area connection 2 connected at 10 mbps. LAN is working as normal. Internet explorer is set on automatically detect settings but it is not working until and unless I disable my local area connection (LAN conn.). I just want that it shud work automatically! i dont think getting a router is a good solution [:s]

Getting a NAT router is the 'best' solution. This will give you the internet connection over the LAN and available to all the computers on the LAN.

Any way, the problem you currently have probably boils down to a routing issue. Enable both connections then run 'route print' and paste the result here.

Speaking of NAT router's specificly "linksys" has anyone had any problems getting any of them to acquire WAN ip's from cable modem's? I've noticed lately alot of people I've helped setup their internet connection the linksys in the status page the DHCP Release and Renew do not work. It will release, but never renew it? After various power cycling modem and router it finally will grab a valid ip.

Just upgraded my modemand had the same problem with my router not getting an IP address. You can do mac cloning in the router to use your registerd nic but that gives away your pc's mac address when being scanned. What I did was hook eveyrhting uo, discoonect the cable line from he modem for a few minutes and then hook it back up tothe cabel modem. My router then got an ip address and from my isp(which changed its static address from what I was getting directly to my pc).

Maybe give that a try. Disconnect the cable from you ISP from the modem for a few minutes, hook up the router to the modem, then plug your cable line back into the modem and you should get a new address from your ISP.

I am using a Linksys Modem and Router, btw.

I've noticed with my ISP (Cox), that if you change the ethernet device the cable modem is connected to, you must power cycle the cable modem in order to obtain an IP address.  Also, some modems have a "power button" but it only puts the modem in a low power mode, which is not sufficient, you have to disconnect the power at the wall usually.
