Public bug reported:

I can make this happen by trying to upload a large file using Firefox
Nightly to https://send.firefox.com/ Within a few seconds (like 10-15)
my wifi stops responding.

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.
