Super Slow Broadcom BCM 4306 rev02

So, I have a Dell Latitude D600 equipped with a Broadcom Corporation BCM4306.

When I perform a lspci -vnn | grep 14e4 command I get:
Broadcom Corporation BCM4306 802.11b/g Wireless LAN Controller [14e4:4320] (rev 02)

I installed the bcm43xx firmware by performing a sudo /usr/sbin/install_bcm43xx_firmware command. The problem I have is that my wireless speed in limited to 1M/sec. I can force it to 2M/sec, but my wireless won’t connect any faster than that. I get the same results whether I connect using WPA or not.

Is there any way I can get it to connect faster?

The BCM4306/2 doesn’t work very well. I get a bit better performance
than you do, but the implementation is lacking something - I don’t
know what.

How are you forcing 2M…I only get 56-100K

The BCM4306 Rev 2 is very old. It was one of the pre-802.11g units.

It will connect faster if you don’t use encryption, but I doubt that is what you
want. You want higher throughput.

What is strength of the AP’s signal as measured in dBm by the 4306? The value
from the iwconfig listing is what I want.

My system lists the strength at -50 dBm, and iwconfig lists the “speed” at 54
Mbps. Pulling a 6 MB file across my NFS network, I get an RX rate of 160 KBps or
1.3 Mbps. Pushing the file is a lot slower. That rate is 53 KBps or 430 Kbps.
This was on a WPA connection.
