Wireless BCM4322 Slow Connection

[gearshifter]

I believe I tried no security with just a mac addy filter and still had problems...

Hopefully this intel chip works out hah.. I hate broadcom.

Hey,

I am experiencing the same issue on a 13.3" macbook pro (5,5) (Maverick 64bit). The

sudo iwconfig eth1 power off

workaround seems to help a little, but I would say it's still slower than with 10.04.

I swapped my wireless out for the intel 5300 which now will kernel panic my machine if powermode is on. I wonder if swapping wireless cards is causing some sort of improper driver load.

Has somebody files a bug report on this already? Turning powermanagement off for the wifi driver worked for me (Macbook Pro 6,2, Ubuntu 10.10/64bit)

Actually after giving this a second try, it still seems to be a valid workaround.
Stick this script in /etc/network/if-up.d (I call the script powermode), and set its mode to 755. Make sure that DEVICE matches your broadcom device.

#!/bin/sh

DEVICE="eth1"

if [ "$IFACE" = "$DEVICE" -a "$PHASE" = "up" ]; then
  /sbin/iwconfig $DEVICE power off
fi

exit 0

Then disable and re-enable your wireless connection. iwconfig eth1 should tell you that "Power management" is set to Off. Now test your connection stability and speed. It is fine for me now

I'm a little new to creating scripts for Ubuntu, can you explain what you mean by "set it's mode to 755"?

Thanks.

It means to change the file permissions. Use this:
'sudo chmod 755 /etc/network/if-up.d/powermode'
(and you can see the changes with 'ls -l')

I`m having the same issues on my MacBook Pro 5-5 13.3" (Maverick 32bit)
Tried the script fix, that seemed to fix it for like 3 seconds after reconnect, got into 53mb/s mode then popped back to 2mb/s and stayed there.
The power off command itself doesnt seem to do anything at all.
Anyone filed a bug report or found a fix for this yet?

All Help Appriciated!

It's the same with me.

Using MacBookPro 55 13" - Ubuntu Maverick 32bit. Ping-ing to the router results in > 600ms reply.

I found that after I turn of security setting (WEP, WPA, WPA2) in the wireless router, and only use MAC Address allow-association, the connection gets A LOT better. Ping-ing to router results in ~100ms. Still makes me worried, since usually in my MacOSX the results is ~1ms. I try the power off option, resulting to 1ms - 6ms, but sometimes still get >100ms reply.

UPDATE :

Another work-around without have to turn of security setting is to pass kernel parameter, intel_iommu=off .Still trying for about 10 minutes now. The ping results in ~1ms and sometimes jump to ~100ms. I'll report if this doesn't work.

I have a MBP 6,2 and powermode does not appear to make any difference at all:

$ sudo iwconfig eth1 power off
$ ifconfig eth1
eth1      Link encap:Ethernet  HWaddr 90:27:e4:e9:xx:xx

Am I "holding it wrong?"

Thanks krims0n32, that workaround worked just fine for me!

Running Broadcom Corporation BCM4322 which was fine on 10.04, but slow as on 10.10
