Wan IP Problem-Help Please

[NightmareTuga]

Hello

I have an Asus Router RT-AC86U.

From time to time, I think that every 15 days, I have no Internet, but the lights on the router do not change. To have Internet again I have to restart the router and Wan always has a new IP, does anyone know how to solve this? Or why this happens?

If it's the AC86U hardware, it will likely get worse until it fails. Othewise, investigate the WAN equipment.

Firmware version?
What apps are you running?
Have you tried a reset and manual configuration?
Are you running a USB device?

Only about a million causes that need narrowing down

This sounds like the lease has expired on your internet connection and the router cannot renew it.

You could try setting DHCP query frequency (WAN - Internet Connection) to either Aggressive or Continuous. But I doubt that will help. If it doesn't help there's probably nothing you can do as it's likely an incompatibility with your modem.

For more clues, when it happens look in System Log if this message appears:

WAN Connection: ISP's DHCP did not function properly.

Thanks, but I always use that system, so far no problems, but now the problem happens.

If you have never reset the firmware, I would do that for a known starting point, and configure it from scratch.

Also, login to your GUI, come back here and click on the link below:

http://router.asus.com/ajax_coretmp.asp

This will show you current CPU temperature. Some AC86U routers have overheating issues.

Thanks for all the answers and help.

I will do a reset and install merlin firmware.
By the way, merlin firmware works with aimesh?

Yes, but you may need to run stock Asuswrt on your nodes.
Asuswrt-Merlin is unlikely to solve your WAN disconnection issue.

 

[NightmareTuga]

I understand, thanks
Why I need to use official firmware on nodes?

In WAN - DDNS - DDNS Status, is Inactive with an yellow exclamation point, but I can connect to the router, very strange.
