Trouble connecting to the internet through ethernet card

[Kronos6948]

Yesterday, I finally took the plunge and turned my box into a dual boot.

Installed Ubuntu by way of Wubi (made things so much easier!), and I was all excited to try out my new OS.

Anyway, I go to connect to the internet, and there's no connection. So, I go into help, and use the sudo pppoeconf command, and I get a response that either a network cable is loose or that something else is using my connection.

I also went into my connections menu (forget what it's called), tried changing from roaming to static (putting in my IP along with subnet and default gateway) to see if that made a difference. Same result.

How do I go about fixing this?

BTW, I'm getting DSL through my ethernet card. Don't know if that makes a difference or not.

First thing's first. Do you have your DSL username/password entered in your router to do the PPPoE connection, or did you use the Windows PPPoE connection wizard when you were booted into Windows. Reason I ask, if you used the Windows PPPoE wizard to connect to your DSL, that's not the best way. You should login to your modem/router's interface and make sure your credentials are entered there.

After that's taken care of, your computer should be getting a private IP address, not your public DSL address. So you should be able just to plug in and go, the computer will pick up a DHCP address from your modem/router.

To be honest, it was so long ago, I don't remember. I do remember that there is a disk that came with the modem that I used.

It might be worth doing a sudo ifconfig, to see if the nic is even recognized first. If it does, you should have at least two entries (eth0 (the ethernet connection) and lo) I purchased a cheap router so I do not have to type in the password for the pppoe after that detail is entered into the router. That way i will not not have to worry about setting that up pppoe on any machine I connect to it. So, if I need to hook a friends machine to the connection, I do not have to worry about changing their network setup.

Oh man.

Step 1: Throw disc away
Step 2: Profit!

If you used the disc you probably have the PPPoE connection configured on your machine instead of the router. Somehow, you need to figure out what your username/password is for DSL. That shouldn't be too hard if you just boot your Windows machine that works with the DSL and edit the connection properties. Once you have that, login to the admin page of your router, modify the connection, and enter the username and password. Once that's done you can hook any machine to your router and it'll get a connection.

I have no router...I'm hardwired. I have an external modem (a paradyne hot wire reachDSL, if that helps), so what do you suggest then?

*edit

This is my one and only computer. I'm basically just configuring this to be a dual boot computer so that I can get used to using Ubuntu, because eventually I'll be building my own computer.

Routers are dirt cheap now. When I had dsl, I had a hard time with it also till I purchased the router. I was also running linux and the support people would not help me. They said I had to run windows or mac only. The SWBell and AT&T dsl support made me feel like garbage. Unless I know there is an actual interruption of service, I do not deal with them anymore. I have been hearing a lot of complaints from their customers all over southeast Texas. With Comcast I have found the same level of expertise in computers, but they do a better job of testing lines. After the switchover of RoadRunner to Comcast, they did rebury my cable after RoadRunner replaced it but left it on top of the ground. Comcast personnel in this area also told me, "I should only run Mac or Microsoft." When I have a problem I just hook up my xp machine to help them get over their anti-linux attitude. When things are fixed. I put my linux desktop back. Since the cable was replaced and reburied, I have not had any problems. (knock on plastic).

@computoman I had the same crap with Verizon when I got my DSL setup. They kept trying to tell me that I had to use Windows or it wouldn't work. Finally I lied to them and said I booted up a Windows computer. All I had to do was hit my router's webpage, so I knew it didn't matter at all what OS I used.

@Kronos6948 If you don't mind spending around $30-40, I'd take computoman's recommendation and get a decent wireless router. Just plug the ethernet cable from the modem into the "internet" port on the router and everything will work. If you don't want to get a router, try these two links. I didn't read them all of the way through, but they look pretty complete.

If one has a spare computer, also I put up a link to setting up ipcop in another thread on this site. He also might want to look at the docs for pppoe also.
