When I suspend-to-RAM (e.g., by closing my laptop lid) and then reawaken, there's a good chance (>50%) the wireless won't work. It's not an issue with my router; nothing shows up in the list of available networks. Then i have to play around with suspend/wakeup and/or turning airplane mode on/off until it comes back on again, or, in some cases, I have to reboot a la Windows.

Thread https://www.kubuntuforums.net/showth...-Surface-pro-3 discusses the possibility it has something to do with kernel 4-15-0-30. In my case, I've seen this problem before, although it has gotten a lot worse since I upgraded. I don't know if that's just a coincidence.
In the meantime, is there a process or daemon that runs the wireless that I could try sending some kind of signal to, or killing and restarting, because repeated suspend-to-RAM is a PITA.
