Hi! And thank you for your help in advance!

Windows Time on my laptop is correct because I manually adjust it. When Im connected to my home WiFi or ethernet cable Im unable to sync Windows time like something is blocking the connection to the NTP server.
The router time is correct and it's set to get the date and time from "Get from the Internet" and it's obtaining the date and time normal without issues. The problem comes from my laptop when Im using my own internet and Im unable to sync it.

Yes, I get an error every time I try to sync my Windows Time using my own Internet
Im going to post screenshots from Windows Event Viewer so you can see the errors and I hope this will help solve my problem.
The first screenshots are when Im using my home WiFi and when I can't sync my Windows time. The second screenshots are when Im uisng my phone celluar internet and the time sync is succesful.

Using my home WiFi and Im unable to sync Windows time:

Using my celluar internet and Im able to sync Windows time: ========================================================================

These are my router settings:

Hi,

If you are comparing your home Wi-Fi to your cellular Internet, then you are comparing two different Internet Service Providers. This doesn't really tell you whether it is the fault of the Archer A6 or not.

Like Sunshine suggested you should connect your laptop directly to your home broadband connection and then check if the time is successfully syncronized or not. 

So, if your laptop has an Ethernet port, then plug the cable that is currently connected to your Archer A6's WAN port directly into your laptop instead. If your laptop doesn't have an Ethernet port, then of course you can't do that test.

By the way, if you open a command prompt with admin rights, then you can also sync the time via the command "w32tm /resync" and get any error messages shown directly. "w32tm /query /status" can be used to show the date and time of the last successful time sync.

Hi, unfortunately I've tried that and it makes no difference I also tried with Google public DNS server and it was the same.

@woozle  I'm sorry for not clarifying. I'm not comparing the internet I want to show that when I change my internet with another ( different from my routers internet) that I'm able to sync my Windows Time. I have tried everything to try to fix my problem but without success. I've tried all cmd commands, registry editing, firewall ... every possible solution on the web

Ok, I see. If you can't connect your laptop directly to your home broadband, then maybe try this: Enter the address of the NTP server you use in Windows into your Archer A6 and then click on [Obtain]. Do you get a "Success", like shown in the screenshot below?

Yes, I have no problems obtaining time in router settings.
Also Im using the same NTP server syncing my Windows Time. I have tried different NTP servers in Windows Time and its the same.
