Wireless connection keeps getting interrupted.

[thebestofall007]

Hello, I am having an issue with my wifi connection to my router consistently getting disrupted every 4-5 or so minutes (but not all the time). When I first installed kubuntu, I didn't have this problem. I am using Kubuntu 12.04 on a macbook pro 4.1 laptop with the broadcom BCM4321 wireless card. I have tried:

sudo iwconfig eth1 power off

command, switching from network-manager to wicd network manager, resetting the router, tried making a script that disables wireless power saving that contains:

#!/bin/sh

/sbin/iwconfig eth1 power off

and placing in the /etc/pm/power.d folder and naming the script "wireless".

the output to the /var/log/syslog of when this event is happening is here:

What it seems to be doing is disabling wireless channels whenever it feels like it, and consequently, my connection, so I have to go into wicd to connect again. It's getting obnoxious, and I have looked all over the internet for the solution but I can't find up-to-date information on this (as I have seen others have it with older versions of ubuntu/kubuntu have similar issues).
