change the connection type, does it change anything?
802.11g, the only type supported by BCM4312
Does another WiFi device tested with the AP have the same problem as the
hardware you initially reported with?
No. Intel's 3945 works ok.
What is the distance of the WiFi device from AP? What is the number and type of
obstructions between the two? If you bring the device close to the AP and
eliminate obstructions, does this change anything?
The two are in the same room about two meters apart, no ibstructions
in between.
Does the issue occur with different APs?
Yes
Is it a regression (e.g. did the problem happen in a prior Ubuntu release)? If
you do not know, could you please test for this in the earliest release of
Ubuntu that is supported as per Ubuntu Releases?
Not a regression. There was the same problem with Ubuntu 10.04.
