Newly connected devices within the same router cannot connect to other devices that were already connected
I have a media server setup running on a ubuntu 24.04 server. I am using a netlink gpon router as a router to connect to the internet as well as connect my devices to the server using wlan. The problem is that sometimes when I try to connect to my server from some devices I am unable to do so or the host is unreachable. When a device gets re/connected to the wlan the device is unable to connect to other devices for a certain period of time. When I try pinging to some devices already connected to the network I get From my_ip icmp_seq=1 Destination Host Unreachable most of the time. But the ping
This question is one of 2 reports of the same problem:
Why is my PC with RJ45 Ethernet connected to router can't ping to other devices that connected the same router via Wi-Fi?
