Linksys Cable Modem on Cox hi-speed

[Xhavier_5478]

hi,
i am running a pc with dual boot XP SP2 and Fedora Core 3 (with the latest Kernel). here is my problem i have a linksys cable modem connected with Cat5. when i boot into Xp i have no problem with internet connectivity, but as soon as i reboot, into Fedora it comes up as logging into Localhost, and can't connect to anything. i tried, unplugging, and reseting my cable modem. nothing worked, i even tried reseting my software network, but to no avail. eventually it will allow me to sign into messenger services, and websites, but i still get Localhost in Terminal windows. this wasn't happening until about a few days ago, if anyone else has had this problem either PM me or just reply in the thread. thanks in advance to anyone willing to help.

I don't know why you need to do all that cable monkeying to get that to work, some extra details like what network card you have and if you know it's trying a DHCP request might be helpfull

As for the 'localhost' thing, that's just the default hostname that Fedora uses. This can be changed in /etc/hostname and the name changes also need to be made in the /etc/hosts file and with Fedora in /etc/sysconfig/network also

and yes it is DHCP'ing

Was there any steps in wondows that you had to accomplish ie: browse to acertain page and add the cable modem and machines mac address to this page, or anything setup wise like that? If so try doing this with in Linux also. Really COX should only be looking for mac addresses of the nic and cablemodem but it may look deaper or linux may change the mac address (don't know why it would, just a possibility). I know with comcast when i changed routers and cable modems i had to reconfigure my setup wiht them by going to a page they provided.

if its dhcping is there an ip assigned?

if there is, then you have gateways and dns to solve

if not, then you are in more trouble

I think it's that piece of garbage modem Cox gives its customers. Maybe when windows shuts down it doesn't release the DHCP address, so it takes a lot of time to renew it when you boot redhat. I recall that a friends Cox dsl/cable modem had all kinds of restrictions on it to prevent multiple computers from being hooked to it...without paying extra.
What is the output from

/sbin/ifconfig

and watch your logs to see what's happening :

tail -f /var/log/syslog

or

tail -f /var/log/messages

alright, first, yes Cox has the Mac address to my cable modem, no linux isn't altering the cable modems mac. Its not the piece of crap Cox modem, because i didn't take thier modem, i bought my own linksys model number BEFCMU10 ver. 3 and i've always had good luck with linksys wireless access points.
