Need to use Comcast broadband connection


Our choices in Tallahassee, FL for broadband service are pretty much limited to Embarq and Comcast. We had service from Embarq, but we moved to another part of town and all we could get is Comcast. Of course, Comcast doesn't provide support for Linux (another reason I don't like them much as a company), so I need help interfacing my Mandriva OS with Comcast broadband.
I found an article on the internet that talked about using a pc with Windows and wireless router to connect to the cable modem, then connecting the linux box to the router (and I'm assmuming disconnecting the PC). I've tried that but I wasn't successful -- I think partly because I didn't know enough to set up a wireless network using Windows.
Anyway, any help I get will have to be somewhat simplified. I hope there's someone out there who can tell me what I need to do.

Thanks

I have a Comcast cable modem and there was zero setup or configuration. You'll need to tell us what type of router you have and the network interface card you have on your Linux system. It sounds like you want a wireless connection from your Linux box to the router?

The only issue I've had with the Comcast modem (mine's a Motorola) is that it can take quite a while after it is powered up for it to connect with the Comcast system. A long time. Sometimes 30 minutes. But I've used several different routers and generally just plug them in to the cable modem and it's good to go. I suspect you may need to do some configuration of the router and if you want wireless, the Linux system will need some configuration.

simple.

from the wall to your cable modem is a coax cable. from the cable modem to either your computer or to a SoHo router (like d-link, or linksys, etc...) should be an ethernet cable (cat5, looks like a big phone cable). if you have USB, then replace that with ethernet and life will be easier.

from the SoHo router, run an ethernet cable to your computer. configure your computer to run DHCP and then configure the SoHo router (SoHo = small office, home office) as you need to. no need for WiFi configuration as WiFi and Linux do not play nice.

good luck.

even if you go straight from the cable modem to your computer, you still need to do the same thing. get rid of the USB connection type and use an Ethernet connection into your NIC (network interface card) and set your NIC to run DHCP, as that is what comcast will provide you i am sure.
