Last week I installed Ubuntu 12.04 on my Dell Inspiron 1520. It used to have Windows, but it crashed and I didn't want to pay for Windows again so I am trying to figure out Linux.
After logging in, I am unable to connect to the internet at all. When the Ethernet cable is plugged in, I cannot connect to the internet. In the System Settings -> Network, there are no wired or wireless options listed for me to connect to.
Other machines in my house can connect directly to the LAN and wireless so I know the internet is working. I have tried restarting the machine with the wifi switch in the on and off positions.
When I ran
sudo ifconfig I get:
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:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
When I ran
sudo iwconfig I get:
no wireless extensions.
Then I installed linux-firmware-nonfree_1.1ubuntu2_all.deb, the non-free firmware for Linux kernel drivers and I am still unable to get online. Now the results of
sudo ifconfig while the computer is wired are slightly different:
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:16 errors:0 dropped:0 overruns:0 frame:0
TX packets:16 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:944 (944.0 B) TX bytes:944 (944.0 B)
What else can I do to get the internet to work on my computer?
