i'm using redhat, and from the 1st install, there was no trouble with my internet, it just worked. ive had a few re-installs now thanks to windows and now my internet doesnt work.
i'm connecting through eth0 with the appropriate hardware, all ip and dns are to be sent from the server. when i try to activate et0, it says it cannot find it's ip. during startup it cannot activate eth0. i tried removing all references to eth0 in the networking and it was able to activate it at startup but there was no connection.
tried netconfig, i really dont know what else to do, and seeing as ive taken windows off, its a real hassle with no internet.
What is the output of lsmod? Another thread shows a problem with a USB connection to their router and they needed to do modprobe CDCEther (at least I think that's what it was--try a search here for CDCEther and you should find it). Hopefully this helps.
Distribution: Fedora Core 1 & WinXP Pro & Gentoo 1.4 & Arch Linux

Rep:
The lsmod command will display a list of all modules that you are loading, they aren't all necessarily being used. With this command you could find out if the module you need loaded for your nic or usb (in your case) is present. I don't have any experience with a USB cable modem connection, but if you don't mind me asking, why wouldn't you just get a ethernet cable connected modem?? I would think the usb approach might be more work than necessary and might give you a performance hit simply by usb vs. ethernet cable. Just curious.
If you haven't tryed yet, unplug the power from the cable modem, and let it sit with no power for 45-60 seconds then plug it back in. When the status light is steady again turn your computer back on; Can't gurentee that this is the fix for your problem but it works like a champ for me.
-P.S. I have Cable modem running through my NIC, hence I can't gurentee that this will work.
rberry: im sharing connection with an older computer that only has usb, and ethernet would only be more hassle. whats really bugging me is that the internet worked first time with no input from me when i installed redhat. ive done a clean install and it still doesnt work.
im going to have to put windows back on (shudder) if it isnt resolved soon as i cant have a pc without internet for much longer.
If you can, post the complete output of lsmod and also your make/model of your usb cable modem. Perhaps there are drivers that need to be loaded for it to recognize it.
Also, you've mentioned that you've re-installed a few times, but the first time it worked flawlessly with no internet problems. I'm curious to know which kernel you chose on installation. If, on your first install, you chose a kernel with USB stuff built in and on the subsequent installs you just chose bare.i kernel then that might be why it's not auto-detecting everything. Perhaps as a last resort you could try to re-install with the usb kernel.
Also, rather than running back to windows, check out some other distributions that you might enjoy moreso than RedHat *cough*Slackware*cough*.
i wont be running back to windows, just installing it so i dont have to keep running around the house. but thats not something i want to do i'll copy up the lsmod now.
I would recommend to just re-install your system if you're going with a different kernel, BUT you don't actually need to do this. You can just put in some modules.
uhci
usbcore
You'll probably need these if you want any usb stuff to work.
modprobe uhci
modprobe usbcore
as root and one at a time of course. Hope this helps you out.
xerosis, usb is a poor connection method, even on Linux. You will find it your interest to go out and pay £10 for a NIC, install, and then connect through that.
Have you spoken to your ISP to make sure this is not a network fault or possible fault with the cable modem? Always worth just a quick call..
i can't connect via ethernet as i've stated above: an older computer is connected as well which only has a usb slot, if i used ethernet and usb, i'd fry the modem. i assume the connection's is working as i have it working on this machine.
