Hi @BeyhanDerya
May I know what is the status of its network light when VR600 loses network? Can the range extender still work at this time?
Please check what IP address the client obtains at this time? Refer to the following instructions:
How to find IP address on your devices
Please try to see if you can ping the modem normally at this time?

Typically, the modem's IP address is 192.168.1.1
