Hey, yesterday I got a new router installed with new ISP. They gave me TP-Link EC230-G1 router, for some reason there is almost no documentation and any support for it. Not a single download file on the official TP-Link website too. But whatever, the issue that I have is that not a single device can communicate with other devices on the LAN. No matter if the devices are connected using ethernet cable or via WiFi. When I go to advanced settings > diagnostics and try to ping one of the devices connected (i.e. PC and Server) I get no response, only "Request timed out" - so not even router can reach these devices. What's weird is all of these devices have access to the internet and can browse without any issues. How can I fix this? I cannot access any of my homelab hardware and IoT devices since the new router :(

My current LAN settings are:

IP Address: 192.168.0.1

Subnet Mask: 255.255.255.0

IGMP Snooping & Second IP: Disabled

DHCP: Enable & DHCP Server

IP Address Pool: 192.168.0.100 - 192.168.0.199

Lease time: 86400 seconds

Default Gateway: 192.168.0.1

Primary DNS: afaik its set to my ISP's DNS server by default
