I have system log problem with Archer A6 version 3.20. Almost nothing is recorded in the system log. It is recorded only if I make some settings or when the router starts. At the same time I have another Archer A9 router. The system log works great - it records absolutely all events - DHCP server and when a client has received an IP address, WIRELESS - when a client is in range and with what MAC address is the device, etc... He constantly records everything, and Archer A6 no records. I think this is a problem with the firmware and should be fixed for the devices we report to you. From the forum I understand that there are other devices that have the same problem as mine. In my case for the Archer A6.
