Public bug reported:
I'm using Ubuntu hardy (development branch) version 8.04 on my Fujitsu-
Siemens M1452G and I've noticed a regression in the range of the
wireless connection (I'm using ipw2200 but someone reported the same
problem in the forum using a Broadcom 4312). The driver connects to the
access point only if it's within 1 to 2 meters. Previously I could
connect to the access point anywhere in my home (distances up to 20
meters).
The output from the 'lshw -C Network' command is:
*-network:0
description: Wireless interface

and the output from iwconfig is (sitting next to the router):
eth1 IEEE 802.11g ESSID:"wlanMann"

However, I only need to move a few meters from the router and I can no
longer connect. I've tried both with and without encryption but I always
get the same behavior.
I also uninstalled the network manager and tried to connect manually:
this worked from a distance of about 6 meters but the link quality would
continually oscillate between about 67/100 and 0/100 making the
connection unusable. I did notice when moving from near the access point
to another room a message in the log that informed me that a better
connection was found and it was switching to that connection, but it
could then never reconnect.
I'm not sure, but this problem may have started with the last updates to
7.10 right before the Hardy beta was released (I had the backports
active).
