Problem with Internet connection

Question

I have Windows Vista and 12.04 on my Dell D630 laptop. I'm using Huawei MT882 modem.

I have installed Ubuntu two days ago using WUBI.

I have tried with USB or ADSL cable but on Ubuntu, Internet connection won't work. On Windows however, it works perfectly (both USB and ADSL cable).

Is there any way to fix this problem?

Output of ifconfig:

And output of nmcli dev:

Answer 1

You may need to manually create a DSL connection, start nm-connection-editor, go to the DSL tab and click Add:

Then enter your username, password and service name you got from your Internet Provider. I think that the service name is optional. Go to the Wired tab and choose the Device MAC address from the network card you connected the modem to. From what I see in your output of nmcli dev, it should probably be 00:1B:9E:bC:0D:DA (eth1).

Then go to IPv4 settings and make sure that the Method is Automatic (PPPoE). Check Connect automatically, click Save and see if it connects.

Answer 2

You might like to try this hopefully it'll work for you as it did for me;

In edit connectios make sure the Connection Name: is Auto(eth0)- NOT Wired Connection,-In the IP v4 Settings set Method: to Automatic(DHCP),- Tick both boxes for 1.Require IP4 addressing for this connection to complete and 2. Available to all users

In IP v 6 Settings set Method: to Ignore, and tick the box for Available to all users
