Link down Prusa Core one+

Hello, 

I am currently setting up my small garage print lab, and my Core 1+/w MMU will not fit in my home office anymore. Unfortunately, it has never wanted to connect to wifi (even when it was a MK4S) which was not an issue since it lived right next to my CAD box. I am hoping to use Prusa connect on it, but sadly it will not even connect to wifi. My other two Prusa machines (Core 1L and XL) connect without issue. I can see my C1+ on the network, but it always has shown as Link down. 

I am assuming I have a bad wifi module but curious if I am missing something.

Try reregistering your printer with PrusaConnect. If your printer is on the network and has an IP address assigned then it's probably not an issue with the WiFi. As a test, does it work with PrusaLink?

Turns out it was a bad update at some point, which caused the machine to not be able to connect to my home network. 

hard reset fixed it all~
