Public bug reported:
I have a Compaq Presario CQ70 which is equiped with a specific button to
switch on/off wireless. Whenever I press it, it always stays red (which
I guess would mean "wireless deactivated")
Let me describe the different steps:
- When you first start the computer, wireless is functioning OK even though the
button is red.
- When you push the button, the color doesn't change, but it seems that behind
the scene the wireless connection is broken. In this state, the browser is not
capable of showing any webpage, it is then in disconnected mode. However, the
network manager still displays as connected for at least 20 sec, before
displaying a notification telling that you have been disconnected. At that
point the network manager displays the green circling icon telling that it is
trying to connect, but this will just never work.
- If you press the button another time (again, no color change), it would seem
that the connection comes back to a state where you would be able to connect
(note that it doesn't connect back by itself). If you want to get your
connection again, you need to right-click on the network manager's icon,
uncheck the "activate wireless network", then recheck it, and after a few
seconds the network manager will try to reconnect and will finally succeed.
I guess that this process is not really what we would optimally want. I guess
that pressing this button should do 2 things:
- Immediately change the network manager's status (just like it would do if you
manually uncheck the wireless network by right-clicking on the icon)
- Change the color so that it is consistent with the wireless' state (i.e.
start green, not red)
This is an extract of iwconfig before and after each step described
before:
After starting the computer, with wireless connected (and able to
browse)
wlan0 IEEE 802.11bg ESSID:"epicwireless-guest"
Mode:Managed Frequency:2.412 GHz Access Point: 00:19:A9:CF:E9:02
Bit Rate=1 Mb/s Tx-Power=20 dBm
Retry min limit:7 RTS thr:off Fragment thr=2352 B
Power Management:off
Link Quality=54/100 Signal level:-61 dBm Noise level=-96 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
When I first press the wireless button, I get this (note that at that
point the network manager's icon is still displaying the blue bars). The
main change is that it now says "Access Point: Not-Associated". At that
point I am not able to browse the web anymore
wlan0 IEEE 802.11bg ESSID:"epicwireless-guest"
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=20 dBm
Retry min limit:7 RTS thr:off Fragment thr=2352 B
Power Management:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
OK, now after waiting for 20-30 seconds, a notification appears telling me that
the connection has been lost, and the icon tries to connect again. If I press
the button again (which would normally lead to changing the color of the button
to green as to indicate that the wireless is ON), I get this iwconfig:
wlan0 IEEE 802.11bg ESSID:""
Mode:Managed Frequency:2.457 GHz Access Point: Not-Associated
Tx-Power=20 dBm
Retry min limit:7 RTS thr:off Fragment thr=2352 B
Power Management:off
Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
Note that we have both ESSID:"" and Access Point: Not-Associated. After
waiting some time (like a minute or so), still nothing happens, it seems
like the system is not trying to connect by itself. So I help it by
deactivating wireless network and reactivating it, the icon shows it is
trying to connect, and at the end I get connected...
I don't really know which information I should provide, I have already opened
another ticket concerning the touchpad deactivation hotkey that doesn't work on
my laptop and have attached a few logs to it, maybe it can be useful:

Please tell me which extra information is necessary!
