How many NAS ports are connected to LAN? (Try just one to trouble shoot). When setting NAS port 'at router end' did you set an IP address that was within the DHCP "pool"? Did you check you had the correct MAC address for the connected NAS port when setting? Try removing DHCP setting from Router and just set a static address on the NAS - Use an IP address from outside the router's DHCP pool (adjust the DHCP pool if needed to have an available set of addresses that can be static within the LAN segment.)shahmanank wrote: ↑01 Jun 2025, 04:59 Yes the model number is F4-423. ...... and IP address for the NAS was made static from router end and its dynamic from NAS end.
{Do you happen to have any TP-Link devices on network? Some of these were manufactured with a DHCP server that would automatically start to issue DHCP addresses if no other DHCP server was detected on LAN. This could be random depending on speed of boot up of particular devices and would cause intermittent conflicts. Firmware updates were available for most (some?) TP-Link devices affected. Set the DHCP server in these devices to OFF if possible to be certain.}
