Coming from an IT and networking background, I am embarrassed to be asking for help with something so basic.
I recently reinstalled Windows 10 (latest version) on 3 PCs in my home, since then these 3 devices cannot communicate with each other, ping, RDP, access file shares etc. All devices are connected to the same wireless network and receive IPs via DHCP from the router (AC3100 running Asus Merlin). I can see the PCs\IPs in the router log. All devices can ping the default GW, access the internet and can ping other devices on the same LAN (ex: firestick, doorbell camera, etc) but not each other. I disabled windows FW on the PCs, I do not have any other security software that can be interfering with communication. AP is set to "not isolated" I am at a loss as to why these devices can't communicate with each other. Is there a "Windows 10 setting" that can be causing this issue ?
