Wireless BCM4322 Slow Connection

[gearshifter]

I am having problems with the wl driver for the BCM4322 on 10.10.

It seems with two different routers the connection is really slow and jumpy and web pages barely want to load. I have tried a usb wireless device, and it seems to work much quicker.

Is anyone else having problems with their broadcom cards with the new update?

10.10 64 bit. Using Broadcom restricted drivers (wl)

ifconfig :

I'm getting the same thing in the 32-bit version of 10.10. Slow wireless network but fast ether. Ping response times are horrible with packet loss on wireless but flawless on Ethernet.

I tried the b43 driver and reinstalling the sta bcm4322 driver, but same difference, its still slow. Any ideas anyone?

I will mess around with it again tonight, but I have tried both drivers, and still have the same problem..


I just bought an intel 5300 half card that I will attempt to put in this computer (xps 1340). We'll see how that works....

Same here for 4312. It was working fine in 10.04.

Same here. There was an issue with power management in the previous version (10.04) that could be worked around by doing:

sudo iwconfig eth1 power off

this seems to help a little with 10.10, but it is still slow as hell.

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

This workaround works quite nicely. Thanks to krims0m32.

I'm using a lenovo g430 with broadcom 4312 wireless controller on Ubuntu 10.10 Maverick Meercat.

Again, thanks much.

The issue for me seems to be my home wireless access point. I tested connectivity from a couple of different locations (work, barnes & noble, etc...) ( I made no changes to 10.10 in any way shape or form ) and it works just fine. It's my home router/fw/wap that is the problem.

[gearshifter]

I've tried your script, and I have tried manually shutting of power managment, but I do not see anything that says power management is off in iwconfig..

If you look at the first post, you can see it even thinks I am not associated to an access point..

Anyone else have this problem?

I've tried this on three routers now.. I think all of the routers are broadcom chipsets too.

gearshifter,

have you tried changing the settings on the wireless router? (wep, wpa, wpa2) And then the various settings under each?
