I fixed my issue, but I wanted to share it in case anyone else runs into the same Wi-Fi connectivity issue I did.
I noticed the IP address for my Ender-3 V3 Plus kept changing between 192.168.37.186 and 192.168.37.187 on my network when it was powered on. This got annoying since I kept having to remove it and add it back to Creatlity print to send print jobs. I decided to assign it 192.168.37.187 on my router and this fixed that issue. It worked for weeks… probably a few months flawlessly.
Today, wifi connectivity stopped even though the printer indicated that it was on the network and showed the assigned IP address. No device on my network could reach the printer or even ping the IP address. I tried deleting and re-adding the wifi settings to the printer several times and then did a factor reset - none of which fixed the issue.
I then removed the wifi settings from the printer again and powered it off. I removed the IP assignment info on my router, rebooted the router and then assigned the printer a different IP address - 192.168.37.186.
When I powered the printer on and added it back to wifi network, it was able to communicate again. No idea why this worked. Perhaps this may have been a router issue instead of a printer issue.
