Wireless keeps disabling itself

Hey all,

I've been having some issues with my Zorin install's wireless connectivity. For some reason the wireless will disable itself "by hardware switch" (or so it says). This often (though not always) happens when I close the lid on my netbook; when I wake it up and log back on the wireless is sometimes disabled.

Thankfully it works again once I save my work and reboot my system, but it would be nice if I could fix this without having to restart the machine. I've tried the "rfkill unblock all" trick but it doesnt seem to work.

Any advice?

Could you please post back the result of the following terminal commands?

lspci -nn
lsusb
sudo lshw -c network
sudo rfkill list all
