USB cable modem connection help without Ethernet card
 

Can anyone please tell me what are the detailed steps to configure my Redhat 7.2 with a com21 cable modem without ethernet card. It is just connected with USB. What should I do to get connected. Thank you to all of you.

I used to connect a Motorola Surf Board 4100 cable modem to my SuSE 8.0/8.1 via USB. I posted about this in another forum. First, you need to have the appropriate USB support enabled (compiled in the kernel or as a loadable module called 'CDCEther'). When you configure your kernel, go to 'USB' and then enable 'Comunication Devices' (the help for that sub-item should explicitly mention cable modems). Second, you need to have the pppd (ppp daemon) running. Third, since we are talking USB, you should have hotplug running.

When you hotplug your cable modem, the hotplugger should recognize it and generate the two characteristic beeps of different pitch (the first for the hotplug event, the second, of lower pitch, for loading the driver). Running 'lsmod' should show that the module 'CDCEther' has been loaded.

If I remember correctly (I now connect my cable modem via ethernet), the modem then showed up as 'eth1' in my setup. I read in different forums that the CDCEther module had a problem with its buffer size in kernel 2.4.18. I am not sure whether this has been solved in newer 2.4.x kernels.

Although, as I said, my experience is with SuSE, I hope it is useful to you as a Red Hat user.

Slow down fantanas!!!!

What does that mean? And how do I do it?

>>When you configure your kernel, go to 'USB' and then enable 'Comunication Devices'
Where is that??

>>Second, you need to have the pppd (ppp daemon) running
How do you make it run?

>>Third, since we are talking USB, you should have hotplug running
And finally what is this???

Thank you guys!!!!

So no one can help me out with this???? :( :cry:

Don't get upset...someone here will try to help you!

It would be helpful if you would cut and paste information from the following command back to a message on this board:

ifconfig -a

this will show what your system sees as your network connection. It may be as simple as not having the right "address" to the internet.

hopefully this will get you a little closer to getting connected--good luck!
