Hello all,
I am new to ASUS Merlin firmware but have a couple observations that most likely may be some sort of defect. I understand ARP requests are normal but when the requester just does not know when to stop, I think it is bugged.
I've noticed the following:
-When a new client (DHCP client in my case) joins, the will send an ARP request for that client IP. This is ideal to increase performance since the router is proactive in finding out the MAC address of the new client. In most cases, that client should respond back to the ARP request. But in the event that the client does not, the router keeps sending an ARP request for this client over and over again. After some time, you can see how these ARP request frequencies can build up.
-When enabling port forwarding for a specific IP, the router also sends an ARP request for that client IP. If that client IP never gets used again, the router keeps sending an ARP request looking for that IP address very frequently. Deleting the entry and even disabling port forwarding does not help. The only way to stop these is to reboot the router.
I don't mean to sound picky, but all these can add up if your router has had a very long up-time. This is even coming to the point where I can honestly say that it is degrading the battery life of your mobile devices such as iPhones. The wifi just does not sleep anymore as it is approaching multiple ARP requests every second.
