Hello,

I have the Archer C7, and I'm connected to a fiber-based ISP.

I'm connected by Dynamic IP, and I get the IP by DHCP. 

I have an issue that the C7 drops the WAN connection. The WAN led turns to a red color.

When I check the network status in the router's interface, I see that there's no internet connection.

I have to reboot the router to renew the IP address and to fix the internet connection.

It happens randomly, every few days.

I've tried to restore the router's configuration to factory default, but without a luck.

What could be the problem?

Regards,

Shai
