Have you power cycled your router already?The only changes I've made to my router lately is to update the wireless "Guest" network that I relegate my 9 year old to using with her toys. My daughter's laptop and tablet must use the wireless "Guest" network because she's not old enough to understand viruses and malware and I don't want that crap having access to my regular LAN.
So for Christmas, we bought her a Nintendo Switch gaming thingy and I had to allow it access to the "Guest" network, and then I blocked it's access to the wider web for now.
I make configuration changes to allow and block LAN devices all the time and have never had a problem.
It almost feels like you are on the "guest" wifi
