When your ASUS Router NTP is not sync, it’s mostly due to faulty settings management. To keep network time updated, your ASUS Router must be in sync with the select NTP (Network Time Protocol) server.
Identifying such problems is simple, as long as you’re aware of how to address the situation accordingly. Let’s see:
To get your ASUS router synced with the NTP, reboot the device and update the firmware of the operating system.
In addition, ensure that the NTP server is set up, and if the issue is still occurring, select an alternative NTP server to sync with.

Why Is ASUS Router Not Syncing With NTP Server?
In order to fix an issue of this kind, it’s first important to uncover all possible causes and reasons for this problem.
That would be the only way to level up your troubleshooting and help you understand the essentials of the problem.
Here’s why your ASUS Router isn’t syncing with the NTP server:
- Improper (Not working) NTP Server Selected
- There’s a Power Problem with the ASUS Router
- Your Router is Running an Outdated Firmware
- Issues with the WAN Connection of the Router
Other reasons for failed sync between your ASUS Router and the NTP server are rarely reported, so focus on the following reasons.
We’ll target all of the problems above, in our upcoming troubleshooting guide, so keep reading further!
How to Fix When ASUS Router NTP Is Not Sync?
We’ve identified that your ASUS Router may not be synced to an NTP server, when particular events take place, such as a faulty WAN connection.
To learn how to effectively troubleshoot the problem, so keep reading!
Solution #1 Setup an NTP Server in Router GUI
Chances are that you haven’t set up an NTP server, using your router’s web GUI. The NTP, or Network Time Protocol allows for clock synchronization in the connected desktops and systems to the router.
Put simply, it’s the time clock of your network and ASUS Router.
- To set up an NTP server, you must have access to the ASUS web GUI!
Follow these instructions to set up an NTP server within your ASUS Router’s GUI:
- Connect your computer to the router via an Ethernet cable.
- Launch an Online Browser on your device.
- Click on the Search Field.
- Paste “router.asus.com” and press Enter.
- Wait to be redirected to the router’s lASUS Login Page.
- Do “admin” as both the username and password for the router.
- Once logged in, go to Administration > System.
- Find “Basic Config”.
- Select “[Time Zone]” and “[NTP Server]”.
- Select an appropriate time zone, answering your real-time location.
- Click the NTP server slider and make a selection from the available options.
Once you’ve made a selection for a time zone and an NTP server as well, press the “Save Changes” button at the bottom-right of the page. This will lock in the changes.
Note: To check if your router’s NTP server is correct, view the Network Time on your system!
Solution #2 Reboot your Router
Performing a Reboot on your ASUS Router will probably refresh the network clocks and fix the problem with the desynced NTP server.
All functions about time and location that applications use based on network time, will also be refreshed along with the router.
Reboot your ASUS Router following these instructions:
- Press the Power Button on your ASUS Router (if your router model has one).
- Once the device has shut down, unplug the router from the electrical outlet.
- Wait for 5 minutes, while the router is disconnected.
- Reattach the power cable of the ASUS Router.
- Wait for your router to boot…
To determine if the reboot of your router made any difference, head back to the ASUS GUI and enter the time zone and NTP tab.
Check if the changes you’ve made previously are still applied and if the network time answers the selected time options.
Note: The key to achieving a full discharge of your router, is keeping it unplugged longer!
Solution #3 Upgrade your Router to the Latest Firmware
To make changes regarding the NTP server and time zone settings of your router, the device should be updated to the latest firmware available.
When it comes down to upgrading your router, you must get the ASUS Mobile Application and sync it with your device.
Here’s how upgrading your router is done on both Android and iOS:
- From the home screen of your phone, tap the ASUS Router App.
- Select “Settings” at the bottom right.
- Choose “Firmware Upgrade”.
- Tap on “Check Firmware Version”.
- The next step is to select “Upgrade Now”.
- Wait for the firmware to be upgraded.
- Exit the tab and close the ASUS Router app.
- Check the network’s time…
Keep in mind that upgrading your router’s firmware might drop the network clock and NTP server changes you’ve made in the previous step.
Access your router’s web GUI, through the connected device and determine if the settings changes are still there.
Note: When your router starts updating, it will restart, hence the WiFi will drop!
Solution #4 Try with a Different NTP Server
Perhaps, the NTP selection you’ve made was incorrect or was not suitable for your router.
Your next move should be to change the NTP server selected for your ASUS Router and check how that would affect the functionality of the network clock.
- Changing the NTP server is also done from your router’s web GUI (Solution #1)!
Here’s how to select an alternative NTP server for your ASUS Router:
- Launch a Web Browser on your WAN-connected computer/laptop.
- Type “asusrouter.com” in the search and press ‘Enter’.
- Log into your router’s GUI.
- Navigate to the Time Zone & NTP Server tab (steps in Solution #1).
- Press the NTP Server slider, so all server options appear.
- Select an option, different from your current one.
- Save the changes by pressing the “Save” button at the bottom of the tab.
It’s important to save the changes made to the NTP server option since otherwise, you would still have the old NTP server selected.
So feel free to test the network time after saving the changes to the NTP server!
Solution #5 Fix the Router’s WAN Connection
If your router is having problems with the WAN connection (the coax cable that connects it to the wall outlet), you’ll be unable to adjust the network time and NTP server.
To address this problem, you should inspect the WAN connection of the router and make sure it is correct.
- Check your ISP’s official website to determine if there are ongoing outages!
If no maintenance or outages are reported, follow these steps to fix the router’s WAN:
- Reconnect the Internet Cable from your Router
- Plug the Internet Cable into a Different Port on your ASUS Router
- Connect the ASUS Router to a Different Internet Outlet (if possible)
Try all of the following steps on your ASUS Router and determine if the device will sync with the NTP server. The problem should go away if the fault was with the WAN setup.
Note: If there’s an issue with the internet provider, waiting it out is your best option!
Solution #6 Restore Router to Default Settings
Performing a factory reset on your ASUS Router is the only way out of the NTP syncing problem currently.
In fact, resetting your ASUS Router to factory defaults is really easy and all you have to do is press the ‘Reset’ button installed on your router.
- Be aware that resetting your router will erase ALL network configurations!
Follow these steps to factory reset your ASUS Router in easy steps:
- Make sure that the router is plugged in.
- Locate the Reset button on the back of the device.
- Press and hold the Reset for about 5 to 10 seconds.
- Keep holding the button while the power LED starts blinking.
- Lastly, you can release the button.
After triggering the reset process, do not interact with the router or press any buttons, hence be patient for the next couple of minutes.
When your ASUS Router NTP is not sync, you should reboot the device and identify issues with the WAN connection.
After that, select an alternative NTP server, upgrade the firmware of the device and in case nothing helps, Reset your ASUS router!
