Constant wireless disconnections after inactivity

I've installed xfce 4.6.2 on a laptop running Debian Squeeze. Everything's been pretty good so far except for this wireless bug which is driving me nuts.

Essentially, if I provide input (move the mouse or press a keyboard key) after ~5 minutes of inactivity, the wireless connection dies and reconnects. This is highly irritating, yet Google and IRC have turned up nothing that could help.

Info!

This laptop is an Acer Aspire 5570z with an Atheros AR5001 wireless card. It's running 32-bit Debian Squeeze with kernel version 2.6.32-5-686 and xfce 4.6.2 installed on top of it. In addition to the standard xfce4 package and its dependencies, I also installed the xfce4-goodies package. I think I'm using NetworkManager version 0.8.1 (at least, that's what the applet tells me) to connect to my wireless network.

Here's what /var/log/messages has to say about the disconnections:

Jun 18 00:35:04 nomad kernel: [15741.103789] ADDRCONF(NETDEV_UP): wlan0: link is not ready
Jun 18 00:35:06 nomad kernel: [15742.675230] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready

Jun 18 00:39:14 nomad kernel: [15990.659198] ADDRCONF(NETDEV_CHANGE): wlan0: link becomes ready

This is repeated over and over.

Here's what dmesg says:

I joined #xfce on freenode and while it was theorized that the problem is one of power management, xfce's power management application did not have any settings enabled that would cause that kind of frequent disconnection. My laptop runs on AC power and it was set to dim the screen after 10 minutes of inactivity, but this problem occurrs more frequently than that.

Please help!

Re: Constant wireless disconnections after inactivity

It would appear that the problem is with xfce4-power-manager. If I kill it when I log in, my wireless works normally.
