Hi, thanks for posting question here.

Can you confirm the model on the router bottom and share us?

Can other devices get the internet access normal from the router?

How did your windows devices connect to the router, wireless or via cable? 2.4GHz or 5GHz wifi band? If no internet access on your windows laptops, you change change DNS on your laptops.

Hi Marvin,

 

Other devices are not having issues to connect to the internet. Windows devices are not doing this all the time.

 

SSID is same for 2.4 and 5 ghz, so i guess windows choose 5ghz for connection. (laptops has 5ghz support)

 

 

Regarding your answer " If no internet access on your windows laptops, you change change DNS on your laptops. "

 

As a network engineer, i can clearly say that its not dns issue. When i check the status of the connection, there is no ip assigned by dhcp on windows device. You can also confirm it by checking the logs i sent you. There is dhcp loop.

 

Thanks

Hi, what is the moel number and operation system of your Windows laptop?

It is suggested to update driver of the wireless adapter on the Windows laptop.
