Wi-fi only works after suspending.

Right after booting (or running 'sudo network-manager restart'), the wi-fi is disabled until I suspend and come back. I wouldn't mind just suspending once every time I boot, but there's a compounding problem with suspend where the pc won't come back from it if I have the nvidia proprietary drivers installed.

This is the result of 'sudo lshw -C network; lsb_release -a; uname -a' while the wifi is disabled.
