Public bug reported:
Ubuntu 8.10.
In Network Manager I have Intel Pro Wireless 3945ABG [Golan] and Belkin
F5D7050 v4000. The built-in wireless card is useless more than about 6
feet from the router, so I need the USB receiver.
Sometimes Network Manager picks up a weak signal from the built-in card.
The problem is that Network Manager occasionally shows the signal from
the built-in card as very strong (even though the laptop has not moved.)
Network Manager then tries to connect to the router via the built in
card, prompts for a password and reports that the computer is connected
when it isn't. Network Manager then seems to try connecting via the
built-in and USB wireless simultaneously, with two requests for
passwords and 'connected' messages when there is no connection. Network
Manager then sometimes crashes completely.
I could disable the built-in wireless card from the Windows partition in
Ubuntu 8.04, but in 8.10 this results in 'Enable Wireless' being greyed
out.
To summarise the bug: the signal strength indicator for the built-in
wireless card is occasionally reporting a very strong signal which does
not exist. Network Manager does not seem to be able to handle two
signals from the same router (one from the built-in card, one from a USB
receiver) successfully.
Maybe that's two bugs?
I've attached a screen shot which shows Network Manager reporting a 100%
signal from Intel Pro Wireless- when the laptop was 9m from the router,
and an accurate reading would be ~5% signal strength at best- and both
the Intel Pro Wireless 3945ABG [Golan] and Belkin F5D7050 v4000 buttons
'on', just before problems arose.
