Wireless disconnects when laptop unplugged from power source

My Ubuntu 11.10 laptop does not connect to my home router when the power source has been disconnected. When plugged back into the mains, the wireless starts working again.

I have a HP Pavilion dv6.

Can anyone help?

Thanks.

The Power Manager is invoked when you switch to battery. /usr/lib/pm-utils/power.d/wireless (part of the pm-utils package) is what caused the same problem for me (Dell D630). I looked through the files in dpkg -L pm-utils, read man pm-powersave and found that I could disable the "feature" by creating /usr/lib/pm-utils/power.d/wireless.

So to fix this, open a terminal (Ctrl+Alt+T) and type:

sudo touch /usr/lib/pm-utils/power.d/wireless
