I don’t see two repositories: packages.zorinos.com and ppa.launchpad.net/zorinos/patches
I strongly recommend you check yourself as well by comparing yours to Software Updater settings - I’m only human and could have missed others.
Once you add these (and any others that may be missing), run the software updater and install any necessary updates. I also recommend that you change the “Download From” to Main Server, if you haven’t so already.
See how it goes after the updates.
Given that the adapter worked fine for two weeks, there is a chance that the hardware may also be failing.
