Currently, the sub is about 2 feet from the router. No other wifi issues in the house. I have also attempted to plug it in directly to the router via ethernet. Updated the Sonos software. Cycled the power on all my Sonos products. Get the same error regardless.
Any help would be great. Thanks!

I keep saying that I will come back into style someday! :)
Thanks, everyone for the suggestions. I kept tinkering around and finally figured it out. My new-ish Asus router has a known issue with Sonos connections.
If anyone is buying new Sonos stuff and as recently got a new router, you might look into issues specific to it. I followed the simple instruction in the linked thread, and it fixed everything.
