My new dls modem doesn't connect the internet. Please help.[SOLVED]

jozmak · 11-26-2015, 04:24 PM

Hello,

I got new dsl modem and can't connect the internet. When I set up the new modem all light come up except the internet light.

This is a very basic simple set up. Includes a dsl moden and a dlink router to be able to use wireless devices. Nothing wrong with the dlink router because when I turn it off the modem still can't connect the internet.

I set up the system 10 years ago and ever since I have never had to do anything with networking interfaces. When I installed a new distro the setup always configured my network and it always worked.

But now my old modem is getting a little bit worn out and my internet service provider gave me a new one.

When I set up the new one, it configures itself and all lights come up except the internet light – power, dls, ethernet everything fine.

I have very little knowledge of networking, because I've never had to do anything about it.

So I don't even know how to start trouble shooting the thing.

Is it possible that I have to reenter the username or passwd for the new modem? But I don't even know where to enter them. I remember vaguely, about 10 years ago I entered username and passwd, but I don't remember how it was done.

I went through several network wikis but I found no useful tips of how to go about fixing this problem.

The old modem connects right away when I set it up, so I guess nothing wrong with may network set up.

Perhaps the new modem can't find the ISP address? Could this be?

Could anyone give me some basic instructions how to go about fixing this?

Thank you

Well, it has nothing to do with your distro.

Surely it came with some basic instructions? If not, ask your ISP for info on setup.

Certainly you will need to enter the username and password given you by your ISP.

For most of them, you simply point your browser at the default address in the setup instructions to open an admin page. Then you enter the default password from the setup instructions to allow access.

It will NOT be plug-n-play, and there are no generic instructions, and there is not much anyone here can do to help without knowing the model of the modem and your ISP's requirements.

So read the setup instructions, or ask the ISP how to do it. It isn't difficult.

Methinks you need to log into your modem and set up your account. See the modem manual.

Edit: Came out second fastest.

Thanks for the replies.

The modem came with no manual. The name of the modem is Camatel. I don't think this means anything, nowadays, everything imported from China.

I call the ISP tomorrow but I don't expect much because they probably say open Windows – Control panel blah blah blah.

And when I tell them I have no windows installed, big silence I am sorry we can't...

I know that when I set up my modem the fist time, I entered username and passwd somewhere and it worked right away.

I'm just wondering is there any terminal commands available to set up username and passwd for the modem, for instance, something like when you set up a new user. Because I suspect that is the problem.

So many things have changed since last time I did this.

It's pity that pppeoconf is not available anymore on debian.

I think vaguely I used that when I set up my connection the first time.

astrogeek · 11-26-2015, 06:21 PM

It is very unlikely that there would be any commands in your distro for setting that up.

A quick duckduckgo for 'camatel modem setup' produces quite a few hits, not all of which looked useful. But this one did.

Download it and even if it is not your exact model, try following the Quick Start guide, ignoring the Window$ only parts - they are really irrelevant. Connect it to network, phone and powersupply and start about page 6 with this...

I installed debian pppoeconf, run it and I got the following message:

Sorry, I scanned 1 interface, but the Access │

check your network and modem cables. Another reason for │
the scan failure may also be another running pppoe │

I'm sure you do not need it, your modem does PPPoE for you.

Thanks Emerson,

This is exactly the modem I have.

I followed the procedure but when entered the ip address they gave the supposed username and passwd box didn't come up, instead it said the address was not available.

I don't know why. Maybe the internet service provider already did some configuration on the modem, I have no idea.

Tomorrow, I call them because, at least, now I have something to tell them.

I report back what happened.

My guess is that your computer has no route to this address 192.168.254.254. Fix your network config.

astrogeek · 11-27-2015, 03:13 AM

Yes, berndbausch is right - it might be that your router does not know where to send requests for that address.

You might want to connect your computer directly to the modem to get it going, then sort out the router addressing. If you need more help, it would be very helpful to post your network topology - router gateway and LAN addresses, dhcp options and how many computers are connected.

Also, if 192.168.254.254 does not work (although it should if that is your actual model) you might try 192.168.1.254 which is another common admin default address.

Emerson · 11-27-2015, 05:36 AM

You may add a virtual interface to your computer before attempting connection.

Code:

ifconfig eth0:0 192.168.254.1

Newer distros don't have ifconfig anymore.

Code:

ip address add 192.168.254.1/24 dev eth0

or shorter

Code:

ip a add 192.168.254.1/24 dev eth0

Assuming 24 is the correct prefix.

jozmak · 11-27-2015, 11:38 AM

Thanks for all the replies.

I apologize for replying late but each time I do the tips I have to unplug my old modem which still works – more less - and set up the new one, and the old modem needs time to hook up again the internet. This is a nightmare.

Here is some info on my computer.

As I said I have a very basic set up one computer, one modem and a dlink router.

I connected the modem strait to the computer as astrogeek suggested but still got the same error message.

I added the ip address to the system as many of you suggested but I am still not able to connect to the admin address.

Did you check on the bottom of the modem for a sticker which has the default admin user name and password? Pretty common on newer ones.
Open a terminal and run this command: route -n You should see output similar to that below:

Quote:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0

Note the IP address under Gateway which will probably be different. Open a web browser and enter it: http://192.168.0.1 (obviously change this IP to whatever you got in your output. Hit the enter key and it should take you to the setup page.
