Thank you! This solved my problem permanently - at least, for today. :-)
Using Saucy (64-bit Ubuntu Desktop 13.10 beta2) with daily updates, my Acer AO722 notebook computer had been networking well after suspending by closing its lid - until something changed less than a week ago. Beginning then, both wifi (Atheros AR9485) and wired networking would fail after the FIRST suspend, and never recovered without a reboot.
Today I read this thread, closed the lid to suspend, resumed (with networking now disabled) and tried "sudo restart network-manager" just once. It reconnected my wifi immediately. What's more, following that one use of that command line, repeated suspends retain my network connection even after powerdowns! I have not applied that CL a second time.
My network connection again stays solid. That seems better than others have reported. But so far, so good!
