fedora 3 linksys router woe,s

[Closer]

Im running Fedora 3 and using a linksys 4 port router. I had no problems with road runner but i switched to dsl and now I have no internet with the router installed. Bypassing router and all is good. The router shows external and internal ip address but i cant access internet. It is hard wired and not wireless. I have reset the router, tried powering down router and modem and entering mac address but all failed. I have heard that there is a specific problem with the kernel in fedora core and linksys routers but i didnt have this problem with road runner.

Thanks for any help

I've run RedHat7.x, RH9, FC3, and FC4 (currently) using Linksys BEFSR11, BEFSR41, BEFW11S4, and the venerable WRT54G routers, and can say that there are NO problems between them. In fact, I often use my *nix boxen to update the firmware in other people's routers.

(BTW, I've also used a D-Link DI-514 without problems, too!)

Now, here are some things to check:

1) Make sure your eth0 is set to DHCP (System Settings -> Network {enter pw} -> Devices Tab -> Select eth0 -> Edit -> Select "Automatically set IP using dhcp" and "Automatically obtain DNS from provider". Apply and Save/Restart).

2) Open browser (doesn't matter - I've used Konq, Moz, and FF) and go to http://192.168.1.1 (default for Linksys). Login with username/pw. At the first screen (usually), you'll see a section there that'll let you choose between WAN connection types. You'll want DSL/PPPoE, and then you'll see a spot to punch in your username/password for the ISP. You may have to tack on the "@mydslprovider.com" after the username:
Login Username: fredjmuggs@nbcdsl.net
Login Password: monkeybiz
Also check the "keepalive" or "connect on demand" feature.

3) The biggest thing to check, though, is if you've got one of those "All-in-One" DSL Modem/Router/WAP thingies. What could be happening is that the two routers' DHCP services are fighting each other on the same sub-domain. What exact make/model of DSL modem do you have (and Linksys router, for that matter)? You may not even need the Linksys.

Also if you cannot dhcp find the dns servers that you use and enter some ip into the machine along with the dns, should be under the same screen you chose dhcp, you can find the dns information by loggingin to the router and clickin on status.

Your isp should also have specific information for connecting a router to the modem.

And I just remembered another thing to check:

Open up a terminal/shell/cli and type:

/sbin/ifconfig

to get something like this:

eth0 Link encap:Ethernet HWaddr 00:0A:E6:C3:A1:B2
inet addr:192.168.1.100 Bcast:192.168.1.255 Mask:255.255.255.0
{blah, blah...}

Now, jot down (or just leave open the terminal and use the cut-n-paste) the part after the "HWaddr" (in my case, it'd be the 00:0A:E6:C3:A1:B2 part). This is your MAC address of the NIC on your PC - every one is different.

Head back to the router's configuration screen, and look for the entry for "MAC Address Clone". Type (or paste) your MAC here, and then enable cloning.

Why? Some ISPs are set looking for your particular NIC, identified by the MAC address. If the MAC you signed up with != MAC being seen, then Access==0. The router will have it's own MAC, which is different from the NIC. Fortunately, they thought of this, and allow you to "clone" the number to the router to make the ISP think you're you. I've found that it's mostly DSL that does this (the cable service here doesn't), but it won't hurt anything to try.

Used linksys netcheck tool wich swithed my router ip of 192.168.1.1 to 192.168.2.1 and all is well. A parently conflicting with dsl modem.
