Bug Description

Hello
This is reproducible with every type of card I've tried.

If a freshly created live-usb session with persistence is launched, the NM triangle still empty, clicked it don't show access points.
If instead I Edit Connections, when ready it start to scan.
Elsewhere it will works at the second boot
Thanks
Fabio

This would be a driver-specific issue.

Can you tell me if from the live session you can run "iw dev wlan0 scan dump" and provide me with the results? You may need to install the 'iw' package for this.

To better understand, if at ubiquity-dm I click to see them, they are showed.
But when live session is ready they aren't showed.

Probably catch the wrong haighway as keyboard layout was used to do before....

That's fine. This means that after 'iw dev wlan0 scan' you'd likely then have results listed in nm-applet. I can't reproduce this with today's daily image (20120412) on my machine, so it's probably also device-specific.

reassigned to Network Manager because this is just a graphical issue, when the accesspoint are showed they can be connected, so this isn't a linux problem.

I am unable to reproduce this on multiple different hardware devices.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:

* Is this reproducible?
* If so, what specific steps should we take to recreate this bug?

This will help us to find and resolve the problem.

Hello,
Sorry is a mine error, #5 is not clear.

* Is reproducible everytime

- Insert the cd and let it run till the page of Language selection.
- If at this point if you click NM icon access points are showed.
- If instead you select a language and press try Ubuntu, live session will be loaded.
- When live session is started if you click on NM icon noone access point is showed, or at least, if you are lucky, they will be showed after many minutes, but not all the times. I've monitores this well.

For this reason i'm thinking that linux has done well it's work as NM too, but my fear is that something is missed again between the language selection window and the live session.

I've tested on:

I observed the same behaviour on a ThinkPad T61, but after installation, not on live session. The list of access points was not visible on first login, but it was after logging out and in. However, after reinstalling the system with a new image cd (14-Apr-2012), I'm no more able to reproduce the bug.

All of the devices listed above seem to be using some form of an rtl driver.

Renzo, what gets listed by 'sudo lspci -vnvn' ? Normally in this case, a T61 shouldn't have rtl devices, I think they usually ship with Intel chipset for wireless...
