Bug Description

Software Center shows "No network connection" warning when there are actually a network connection.

It probably relies on Network Manager for it. But I don't use Network Manager. In the past six years, it never worked for me. Not when I was on dial-up, not when I used DSL, not when I use wireless now.

Can Software Center take more smart approach, and actually try *using* network. If that fails, it should properly handle errors.
Because when there is no network connection, but Network Manager tells it is there, you should properly handle errors anyway.

Not sure if this is the same bug but I've noticed that this message is always displayed when trying to install a .deb file (which will presumably not have an entry in the Ubuntu review database).

I installed using x86 Alternate because GUI setup would crash and not complete install.
After i booted first time after using Alt, disk. i noticed that the internet would work but Network Manager and Software Center would not show an Internet connection. After a reboot the entire internet connection didnt work, no IP nothing. I modified /etc/NetworkManager/nm-system-settings.conf to Managed=True, because Network Manager said Device Not Ready (AR5007). The internet worked afterwards but the Network Manager still showed disconnected. Same thing with Software Center

I was also getting the same error when I try install from Software Center. It shows the search results, more info and other details but when click on install It will say "No internet connection".

But After sudo apt-get update the issue got resolved.

I'm using a ralink wireless usb dongle from linksys with the driver RT3572STA and NetworkManager doesnt handles it well so I disabled it and manage my connection manually with iwconfig. So I get the message also on software center about no network connection so I had to go back to apt-get. Also it seems that the update-manager is affected it downloads updates fine, but the changes of these updates cant be read on the GUI since it shows the same error, no network connection.

I've set this one as a duplicate of bug 911706. Indeed, that is a later bug, but we have been tracking the fix for this one there, and furthermore, that bug includes a very informative comment from mpt (comment #4).

If anyone would like to add any information from this bug or any of its dupes, please feel free to do so in bug 911706.

Many thanks, all!
