I am a Comp Sci student and I had to replace my dev laptop with an old Dell Inspiron 1150. First tried loading Ubuntu 13.10 but it wouldn't render graphics correctly on this old machine, so I put on 12.04 LTS instead.

During install from DVD, it recognized internet connection (I had an ethernet cable plugged into my wireless router and the linksys wireless-G adapter plugged into the bus, so I don't know which connection it was using). But now that the OS is installed, it says Network Disconnected and I can't get it to recognize either connection.

the output of

sudo ifconfig

is:

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:65536 Metric:1

TX packets:192 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:15744 (15.7 KB) TX bytes:15744 (15.7 KB)

and the results of

sudo lshw -C network

is:

*-network UNCLAIMED

I manually typed this in, so hoepfully no typos

  • "unclaimed" usually means that there is no driver installed - please search here for broadcomm or BCM.
