Comment 3 for bug 1128017

So the command is running, but fail to establish a simple connection. The test is hard-wired to connect to http://cdimage.ubuntu.com.

Can you do a couple things:

1: run the attached script from a terminal twice, like so:

./network_check -a; echo $?
./network_check --url=http://www.google.com -a; echo $?

and let us know the results.

2: if the first one fails (the attempt without the --url), can you try the following:

ping cdimage.ubuntu.com

or try opening http://cdimage.ubuntu.com in a web browser.

This is really a basic test, and if your networking is connected and working properly, the only reason this should fail is failure to reach a specified website.

and one other question,

do you happen to have both ethernet and wifi connected to the same network at the same time? there's a SLIGHT chance that that could cause connection problems (I've observed that before myself, but rarely).
