Users’ devices keep disconnecting of Wi-Fi for half minute and reconnect again, this issue occur every 30-45 mintues when only WDMC is attached to network(modem), tried other ports on modem, reload both WDMC and modem, I also tried to connect WDMC to switch and then from switch to modem with no luck.
You need to log into your router and set up a reserved IP address for your WDMC. This should be outside the range of the DHCP server.
Firstly, login to your WDMC dashboard. Under Settings - Network - select Network Mode - DHCP.
Next login to your router dashboard. Under LAN settings look for the DHCP pool settings. The DHCP start / end range is probably set to 192.168.1.2 to 192.168.1.255. Set the end IP address to 192.168.1.199. Then manually reserve an IP address above 192.168.1.200 for the WDMC, e.g. 192.168.1.201. You will need to specify the MAC address of the WDMC in the router interface so that the router knows which device to assign the IP address.
