Explanation

When a router is replaced, the new device has its own DHCP server, which may have a different IP address pool, subnet configuration, or gateway address than the old one. Client devices retain their previously leased IP configuration, which is now stale and incompatible with the new router. Running 'ipconfig /release' followed by 'ipconfig /renew' (or simply reconnecting) forces each client to request a fresh IP lease from the new router. This resolves IP conflicts and configuration mismatches. The server going down is unlikely to cause this. Static IPs would not typically be the cause in a SOHO environment. A malfunctioning firewall would cause different symptoms.
