Mesh router shows uptime longer than the device has existed

The most likely cause is that the router's uptime counter is not reset by a fresh setup or by a factory reset that only clears settings, or the device reports time from a clock or firmware value that was set incorrectly, so the number does not match the real purchase date. 1. Check the router's clock first. In the mesh app or admin page, look for Date and Time or System Time. If it is wrong (for example set to a date in the past or using a stale internal value), the uptime will look wrong too. 2. Enable automatic time sync. In the same settings area, turn on "Sync with internet time" or "Use NTP," then reboot the unit and recheck the uptime. 3. Restart each node. Unplug the unit for 30 seconds, plug it back in, and wait several minutes for it to reconnect. Uptime counters sometimes only refresh after a real reboot. 4. Update the firmware. Open the mesh app's firmware or update section and install any available update. Counter bugs are sometimes fixed in newer releases. 5. Check the uptime from a computer if the app shows something different. On Windows, open Command Prompt and run "arp -a" to find the router address, then open that address in a browser. On macOS, use the same address in Safari or Chrome. Compare the reading there with the app. 6. If you have a spare moment, do a factory reset on one node and set it up again, then check whether the uptime starts from zero. If none of this works: the value may simply be a display bug, which is harmless if the network works normally. Contact the manufacturer's support with your model number, firmware version, and purchase date, and ask them whether the uptime counter is known to be wrong on your firmware. Keep your Amazon order record in case you need proof of purchase.
