MOTOROLA SB5100 SURFboard Cable Modem Support?


Dear Linux users.

A week ago I bought a SB5100 Cable Modem by MOTOROLA.

May somebody notece me where could I download it's Linux support.

I contacted MOTOROLA technical support but they tould me that
they haven't wrote a Linux USB support for this type. They tould me
to find at the Internet.

I would be grateful to anybody who refers me to the place I could download
the Linux support for this type.

It is:

MOTOROLA

SB5100E
SURFboard
Cable Modem
USB

Thanks.

Do not see the modem

Hallo!
I have Motorola SURFboard SB5100i. And my Debian linux don't see device.
I tried on Debian with
- kernel 2.4.18 and 2.6.8.1
- newest unstable Debian packages
- USB and Ethernet connection (i prefer usb)

When I create new eth0 interfaces (before that of cos "modprobe usbnet" work fine) with properly HW ADDRESS, DHCP can't connect do the device.
When I to try make new interfaces other than eth0 (ex. eth1) can't find device associate with HW ADDRESS.

I have PC, with Ethernet card 8139too, AMD K7.

Can anyone with properly configurated SB5100 help me??
THANKS!!

Motorola Surfboard SB5100i

I know it is possible for this modem to work under Linux becase it works perfectly with Knoppix version 3.4 on bootable CD. I am working on getting it recognised by my Xandros distro. Try

http://tldp.org/HOWTO/Cable-Modem/pr...html#USBCONFIG which you might find usefull


Knoppix is a debian based distro

I'm also trying to set up a Xandros based machine using a Motorola cable modem to connect to Optus here in Australia. I can get my box to talk to the Modem (In my case the modem itself has an address of 192.168.100.1) , but I can't work out how to send a request for a lease on an IP address which Optus recognizes as a legitimate request. Note that I'm using eth0 not the USB connection, so setting up the network card was simple.

I've read the HOWTO on Motorola Surfboards and tried most of the relevant things suggested there. My log consistently says "No DHCP offers received." When I talk to Optus help desk they tell me they can see my network card or my router (I've tried a few different layouts here) but they are not getting any requests for an IP address. It seems that I'm just not asking in the right way, but of course the help desk can't tell what the right way is! Where do I go from here? Does anyone out there know where I can find what information Optus needs?

Cheers
Ian Christie.

Motorola Surfboard SB5100i

I have finally found out how to get my Motorola Surfboard SB5100i recognised and working as a usb modem on my Xandros OS.
First I had to open the file /etc/devices/drivers
then at the bottom of the text file add a line that read
95 CDCEther
save the file
go to the run command and run xangenmodules
restart the computer
then run the connection wizard and it then recognised the Surfboard under cable modems
then it worked!!!!!!
This advice is fairly specific to Xandros but I hope it helps, and a big big thankyou to everyone who gave me advice and info!

Problem solved

I solved my problem by searching for every possible post here and elswhere which could be relevant. I found a passing reference to dhcp which suggested it wouldn't work if there were two NICs in the machine. I had two! Took one out, turned everything off (including the modem) then restarted in this order: modem; router; linux box. Works perfectly. The starting order matters apparently.

What I heard

I thought that I would pass on what I saw and hopefully this will help others.

If you do the following it may help

Log in as Administrator.
Open the /etc/modules file.
Add a line at the bottom with the following text: 92 CDCEther
Save the changes
Restart.

Hope this works. (I have also seen the following text use so maybe you can have two choices.
95 CDCEther.) Let me know. I have seen this but I don't actually know how to do this. If it works maybe you can tell me how to open the file or better yet where?

Hi,

I've got a Motorola SB1500 too and I'm connecting to Telewest using Mandriva LE 2005. I found a link that said to load CDCEther and usbnet as drivers. This creates an eth2 (in my case) defining it as Broadcom (something or other)/Cable Modem. I then configure this using Telewest's url (Blueyonder) and everything's great. I was already registered with them through XP. The final bit of the link says to put the modules into /etc/modules.conf to allow for reboots. So I put the folowing lines in:-

CDCEther
usbnet

However, when I reboot, eth2 doesn't appear and I have to manually reconfigure. It works again, but it's a pain. I suppose I'm not using the correct format, but I can't find any useful guides which don't blind me with science. Any guidance would be appreciated.


Cheers

KenMac

Hi,

I added the following line to #root/etc/modprobe.conf

alias eth2 usbnet

The network now starts up when I boot. Eth2 is what my Motorola Surfbord was allocated when I used DrakConf(ig?) to set up my network. Eth0 and Eth1 have been allocated to the Firewire ports on my Firewire/USB2 card and my Creative Audigy card. Don't knoe why Firewire is seen as Ether ports, but XP does the same. Since I used Mandriva's System Setup GUI to set things up in the first place, I can't tell what Linux commands were generated, but I did see "modprobe usbnet" in the log. It seems some Surfboards/Linux versions use CDCEther and some use usbnet. If in doubt, try either or both.

I left #root/etc/modules.conf as per my previous reply, but I suspect they may not be needed. Now that I know what works, I'll tinker with what is needed and what isn't.

That's as much as I know. Hope it helps.

Cheers,
KenMac
