[Solved] Broadcom_wl constantly shutting down wifi when on battery.

Hi Guys,

I have this weird bug with my wireless driver when its running off battery. It seems to drop the connection every minute or so and then reconnect.

**Edit**
It seems power management is enabled when I boot up my machine. I have done "sudo iwconfig eth1 power off" and this seemed to help fix the problem. Is there a way where I can permanently turn power management off?

00:19.0 Ethernet controller: Intel Corporation 82567LM Gigabit Network Connection (rev 03)
0c:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

Create a file in /etc/pm/power.d called wireless and put this in it.

#!/bin/sh
/sbin/iwconfig wlan0 power off

Edit: Your wireless most is called wlan0. type iwconfig in a terminal and find out and replace wlan0 if it is not wlan0 with whatever it is actually. Sorry if it is indeed eth1 and if so just put that instead of wlan0.
