ASUS RT-N66U: Other odd system log messages explained

Aside from the, ‘WAN Connection: Ethernet link down.’, message I was seeing in my ASUS RT-N66U system log, there are two other error messages that appear often.

miniupnpd: unsupported NAT-PMP version : 2

This message appears in my log every hour on the hour. As near as I can tell it doesn’t cause any problems with my Internet connection or general network performance. I’ve figured out it only occurs when my wife’s Mac Mini is turned on. The Mac works just fine  during and outside times the error message is being logged. Either Mac OS itself or some program she has is using UPnP in a way the ASUS router doesn’t care for. I don’t have a good answer on this outside of saying it doesn’t seem to affect much.

kernel: eth1: received packet with  own address as source address

I have two access points in my home, both with the same SSID. The first access point is the one built into the ASUS RT-N66U, the second access point is an old Netgear router with everything but the access point functionality turned off.

This error occurs when a client moves from the ASUS RT-N66U to the Netgear access point. The network is general is not affected. The client moving between the two access points will lose some packets. The packet loss isn’t noticeable unless you are looking for it.

  1. Whew the own source address one was making me nutty. I thought something was wrong but everything seemed to be working alright

  2. Hi,
    you say that “This error occurs when a client moves from the ASUS RT-N66U to the Netgear access point. ” How sure are you about this? I have also an extra access point and another repeater. Even if I disconnect these I receive the same message so in my case it can’t be due to this. There are pleanty that have this problem but I have not found anyone yet that have a solution.

    1. When I turned off my second AP the error stopped. Turning it back on started up the error again. Then it looked like I could cause it to happen by moving far away from the ASUS router. It’s possible that’s all coincidence though. The error never seemed to cause any problems. Do you have any problems that are related to the error message?

      I ‘fixed’ it by moving the Merlin Firmware. It solved a bunch of other problems I was having, I’m very happy with it.
