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 succeeds within anywhere from 30 to 290 pings if I continue pinging.
Even then the new device can only connect to the device which it established connection by pinging and not other devices on the network. (I don't know if it is normal behaviour but if I was actively using the device connected to the server and I briefly disconnects and reconnects the device to the network and then try pinging I get a packet loss of about 5 packets and then the connection succeeds)
Once I try to ping the new device from the already existing device(Server) in the network the new device can instantly connect to the existing device.
I also tried keeping my PC as my existing device and disconnected my server from the network and then reconnected it, and the server too has to ping the device continuously to the existing device(PC) to connect to it but the PC can instantly connect to it if the PC now pings the server.
My wlan encryption was set to WPA2 Mixed with WPA TKIP enabled so I changed it to WPA2 but doing it didn't fix it either. I have already tried tweaking the firewall and Dos protection setting, resetting my router etc. My firewall is now set to low and Dos protection is disabled. Don't know if it is relevant, when I checked the connected clients list I could see a column expired time for all clients, set to 300 sec. Is there any solutions or workarounds to this problem(like repeatedly pinging the devices on my network with an interval from the server using static ip for all clients)?
Here are my wifi settings:
