I think I'm back to believing that in linux resume and wireless is too fussy. It's also aggravating
I am on the road today with this laptop which I though was working, but when I opened it up just now it resumed ok but wireless was not working. Finally (after a few minutes) the network I wanted to connect to was found but it wanted a passphrase-for an open network. I had to reboot and then it worked. If you have to always reboot to get services working-something is wrong.
