WiFi on Cetus2 doesn't connect

My wifi router shows up but when I type in the password nothing happens. Once out of about a dozen attempts, I got a little green check mark, but it quickly disappeared. I’m about 15 feet away from the mesh router. I’ve also tried connecting via a usb cable and that seems to work from the wand end. But when I try to print a file, it says it is corrupted. The same sd card works fine when plugged into the cetus2 directly. Any ideas what I should do to fix either of these two issues?
