Can't connect to the router

[maqtanim]

I am using Ubuntu 12.04.

Previously I was using a DSL connection. I used to connect that network using pppoeconf. Recently I bought a new connection (to be precisely this one). After connecting the cable to my PC, Ubuntu doesn't get the modem. Even I can't access the router admin panel by typing 192.***.***.***.

Any Help?

In a terminal window type ifconfig what do you see? Remember you are no longer using the DSL entry in Network Connections it needs to be removed. Under the Wired section you need to have an entry "Wired connection 1" or some other name which has Automatic (DHCP) set.

Turn the machine off. Make sure the router is turned on and start the machine. It should be on before the computer is turned on for the system to find it, are all the lights lit?

The result of ifconfig is:

ifconfig
lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:112 errors:0 dropped:0 overruns:0 frame:0
          TX packets:112 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:8512 (8.5 KB)  TX bytes:8512 (8.5 KB)

I've totally removed/deleted the DSL connection from the network manager. But there is not any wired network listed either (like your screen shot). May be the settings from the previous DSL connection making some conflicts. But I don't know how to solve the conflict.

Followed your instruction and all the lights of the router lit during the procedure. No problem with the router, I can even connect to that router and browse internet with another laptop (which is running Ubuntu 12.04) with both the wired and wireless connection.

Your eth0 is not being seen since you just have the loopback showing? Do a 'lspci' and see what you have hardware wise?

hi maybe nm-tool will shed some light on the matter:

nm-tool

also check your /etc/network/interfaces to see if there's any left over stuff about your pppoe connection in there

cat /etc/network/interfaces

I'm not at all familiar with the version of Ubuntu you are using. But..I would try and manually set up your network connection using your Administrator account and make sure you have allowed the connection to be used by all users.

Also check the Ethernet LED on the network card on your computer to see if it's lit and flashing.

If that don't work- buy a book on Relaxation & Calming Exercises and prepare yourself for a few hours of stress and burnout
