Verify the DNS server settings on your router and individual devices.
Test DNS Resolution
From a connected device (if possible), try pinging an IP address directly (e.g., ping 8.8.8.8) and then a domain name (e.g., ping google.com).
Inspect UPS Status
Check the status lights and battery levels of all UPS units powering network equipment.
Check Building Power
Verify if the entire building or office area has power.
Reboot Core Equipment
Attempt a controlled reboot of the primary network devices, starting with the modem/router.
Inspect Core Equipment
