Hi, I have this problem with a Broadcom wireless card:

$ lspci | grep LAN
02:09.0 Network controller: Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller (rev 03)

Is very slow with Hardy, with Gutsy i've never had a problem...

Look at this:

$ iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

wmaster0 no wireless extensions.

wlan0 IEEE 802.11g ESSID:"nerds"
Mode:Managed Frequency:2.462 GHz Access Point: 00:15:E9:01:B5:48
Bit Rate=1 Mb/s Tx-Power=27 dBm
Retry min limit:7 RTS thr:off Fragment thr=2346 B
Link Quality=75/100 Signal level=-56 dBm Noise level=-69 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

The Bit Rate never change in this laptop, even with Signal level=-5dBm, with the laptop side by side with de wifi router. I have another 3 machines in the wireless network and there is no problem with them, one with Ubuntu Hardy on a IBM Thinkpad, a Mac and a Xubuntu in a EeePC, the Bit Rate is between 11 and 54Mb/s in those...

Some workaround for this?

Thanks in advice

I' ve tried doing

#sudo iwconfig wlan0 rate auto

or

#sudo iwconfig wlan0 rate 11M

etc...

but it doesn't change the bit rate, i did

#sudo ifdown wlan0
ifdown: interface wlan0 not configured

Hmmm... so I checked my /etc/network/interfaces file:

auto lo
iface lo inet loopback

and that's it...

In the EeePC the file is exactly the same, but it shows bitrate=54M

There is another way to configure the bit rate???

I was having issues in gutsy with the broadcom stuff. I went to using NDisWrapper and the windows drivers and it cleared it up. Have you tried that?
