Cable modem Via USB

phsythax · 08-26-2006, 12:18 PM

I have connected my box with a Cable Modem via USB, but it cant connect to the internet. I have enabled USB DSL modem support in the kernel (device drivers-> usb support-> USB DSL modem support->[*] USB DSL modem support & all other options) but it still doesnt work, Can anyone help me?

Code:

# lsusb
...
Bus 003 Device 002: ID 07b2:5100 Motorola BCS, Inc. SurfBoard SB5100 Cable Modem
...

What exactly have you tried? Have you checked /var/log/messages for a device name? After you have a device name, all you need to do is 'dhcpcd', 'ifconfig <device> up', and set up the DNS server name in '/etc/resolv.conf'.

Before you connect or turn the modem on, type

Code:

tail -f /var/log/messages

This will show the end of the messages and will follow them as the file grows. Next, attach the modem via USB and turn it on (after you've loaded your modules, of course.) You should get several lines telling about the device. Somewhere in there you should see a line with a device name, such as

Code:

Aug 27 09:16:40 darkstar kernel: [4295058.178000]  sdc: sdc1

If not, then you need to obtain and/or load a different module. If possible you should try to connect through an ethernet card; that's MUCH more likely to work, and shouldn't require any additional modules.

You are aware that hooking to the modem with usb will be much, much slower than using ethernet? Adding an ethernet card is a $10, half hour deal.

yes i am aware of that fact, but untill my long ago ordered new modem arrives, i think i will use the not-fried usb port that i got left in my old modem.
