I will note that sometimes, restarting network-manager doesn't work, especially if I have put the machine to sleep prior to trying to access the network. Here's a dmesg where it did come back after network-manager restart.

Restarting network manager via service network-manager restart temporarily resolves the issue. This issue began appearing a week or so ago -- almost definitely not a month ago; my wifi used to be fine previously.
