Unfortunately I won't be able to update to Hardy due to a problem with wireless connection. In fact, today I'll be going back to Gutsy since I cannot work without my wireless access. This seems to be a serious regression and although I filed the following bug on Launchpad it seems that it's not considered a show stopper. The text from the bug I've filed is the following:
------
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

physical id: 3
bus info: pci@0000:01:03.0

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

Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0

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.

If anyone has any ideas what might be causing this I would sure appreciate your input. Thanks.
