Cable Modem Help Needed

DavidPhillips · 12-23-2002, 12:29 PM

well it's worth a shot

we need the output of lsmod and see what modules are loaded, because he said it shows the modem

so just a wild ass guess, I would say

Code:

modprobe pegasus
echo "alias eth0 pegasus" >> /etc/modules.conf
depmod -ae
dhcpcd

And yea, USB sucks. There is no way I would consider using it as a network connection

Thanks for all the info. As I have some time off this coming week, I'll play around a little more. Hopefully Santa will bring me a new network card

I'll let you know what happens.

Thanks

After all the info from you guys and talking to some others, it came down to a very technical issue. Plugged in the Ethernet cable to the non-defective Ethernet card and then TURNED THE MODEM OFF! The cable installer never mentioned that when the connection is changed from USB to Ethernet, the modem needs to be powered down. Well anyway, thanks to all of you for your help. I feel rather stupid in one way, but in another sort of vindicated because I was the one who decided to turn the modem off.

Thanks Again!!!

The usb cablemodem is useable with the usb driver CDCEther. I find my connection is much faster using the usb instead of ethernet connection. In suse, I believe, you will have to discourage the system from recognizing it as a usb modem tho, it should be treated as a usb ehternet card. I have used the usb modem setup with the CDCEther driver (+ all of the appropriate base usb drivers) in Mandrake, Redhat, Suse, Slackware, Sorcerer, and Lunar linux. Oh, Debian, too (unstable branch)...

Yes I have to turn my modem off too. Any time something is changed. Plugging in a different nic it will need to be reset, because it uses the mac address. I don't have usb on mine though.

XavierP · 12-24-2002, 04:14 AM

Mine also needs resetting if anything changes. A lesson to us all - sometimes it's worth going all the way back to basics.........

DavidPhillips · 12-24-2002, 05:31 AM

Yes but I thought we were trying to get usb working, I don't think that was solved. Suddenly it's ethernet

ethernet is no problem.

XavierP · 12-24-2002, 06:32 AM

From what I've been told when I first joined this forum, RedHat and, indeed, Linux don't do USB to cable modem connections. You could have a look at my earliest questions/posts but I think you'll be looking at ethernet.

Darkstar · 12-24-2002, 07:21 AM

The reason originally to get the USB working is that is what I had set up for XP (I have a dual boot system), but I wanted to be able to use the ethernet so I could have a router set up. I had actually wanted to have the ethernet all along but had this little problem. Hopefully you guys don't feel as I have wasted your time on this.

UB_KMA...Do you just do a modprobe on the CDCEther driver and it sees the usb connection?

DavidPhillips · 12-24-2002, 10:08 AM

No not at all.

And you could easily add another nic for 15 bucks and have a router.

Some usb cable modems work but there's not much info on yours. Some of them use the pegasus driver.

UB_KMA · 12-24-2002, 10:17 AM

Yup, if the module is available, and it is standard with the stock kernel in the distros you list u use. Just modprobe CDCEther, and the lil' lights on the modem should start flashing. If you have trouble, let me know. I've set up the usb cablemodem on lot's of distros with success.

The only problem I had with suse was it kept trying to treat it as a modem, instead of a ethernet usb connection. I believe getting rid of the modem driver module (rmmod "module name which I can't recall, sorry") fixed it. The CDCEther driver is available as a selection in all of current gui configurators. Um, I can't recall what CDC stands for Communication "something" Class, I believe. The problem with just doing a modprobe in the major distros is that most of them have configuration scripts on top of configuration scripts...and so on....and so on....and some dont wan't you to touch your modules.conf file (they overwrite it if you do, and ruin your changes)...sooo, while a modprobe would probably get the system to see the modem, it still might not work right utill you changed settings via the gui's.

If you ever get tired of being restricted by user interfaces try Slackware.

UB_KMA · 12-24-2002, 10:21 AM

Oh, also, David is right in a way, the modprobe will allow the system to "see" the modem, however to actually USE it you have to configure your connections appropriately, assigning dhcp to ETH1 ( it will be the last available ETH port after your internal cards)--assuming u use dhcp, etc...

I had the exact same thing under RedHat 8 and Mandrake 9 - I tried fooling the system into believing that it could see the USB as a network card, it didn't work for more than a few minutes. As far as I know, none of the Linux distros support usb conections for modems (please correct me if I am wrong). I installed an ethernet card and hooked it to the modem and it works fine.

Mandrake 9.1 does support the motorola surfboard. The module used is called CDCEther. this IS the USB driver it is read as a network card, however, suse 8.1 does not have this module on any of the cds and i do not believe 8.2 does either i am currently looking for a copy of the module, and i will update when i find it.

shi*can the USB already... USB was set up for the Windows winnies who didn't want to open their computer cases. Besides, the through-put on usb is abismal compared to ethernet. Buy an ethernet card, Linux will find it in most cases automatically and get the cable out of equation.
