I think I may have hit this as well. I installed the A+ over last weekend and it's been humming along just fine. (Routing + NAT)
My wife just texted me and said there is no wifi in the house, but wired devices (Playstation 4, etc) are working.
She doesn't want to deal with power-cycling the A+ so I'll check it out when I get home tonight and update this post with additional details.
Thanks
UPDATE: The LAN was not working either, there was a confusion in the texts with the wife
I power cycled it and it just got stuck at a white screen. I've posted a new subject since it seems more serious/permanent than this bug(?)
