Hi Everyone,

Every now and again I lose WAN connection, and I'm trying to understand the root cause. Here are the relevant og entries from one of them:

Code:

Why question is, how can I find out what "some issues" are?

Cheers,
Andy

The connection between the router and the modem was broken. The router has no way of knowing why that is so it says it's due to "some issues".

Examine the log on your modem. It's likely that it rebooted itself. Or you've got a faulty Ethernet cable connecting the two devices.

The cable is "known good", in that I've used it for a long time with other equipment, and securely plugged in at either end.

There is no modem log, the "modem" is a fibre ONT. The Asus sets up the PPPoE connection and authenticates etc. I've witnessed it going down, and the fibre light is on solid, just the internal network light stops flashing due to lack of activity, so it's still connected.

Surely the Asus should know if the PPPoE connection goes down and why?

If it were a soft PPPoE error you would get a different set of error messages. The log that you posted shows a hardware disconnection.
Code:
Jul 15 13:40:57 kernel: eth0 (Int switch port: 3) (Logical Port: 3) Link DOWN.
Jul 15 13:41:01 WAN_Connection: WAN(0) link down.
Jul 15 13:41:04 kernel: eth0 (Int switch port: 3) (Logical Port: 3) Link UP 1000 mbps full duplex
Jul 15 13:41:07 WAN_Connection: WAN(0) link up.

I also have a problem with occasional connection drops, but I solve it through the checkwan script, and if the connection is not verified, the wan interface is restarted..

Code:
Jun 27 16:20:02 (ChkWAN.sh): 14952 v1.17 Monitoring WAN connection using 5 target PING hosts (213.81.233.155 94.140.14.14 94.140.15.15 9.9.9.9 1.1.1.1) (Tries=3)
Jun 27 16:24:10 WAN_Connection: Fail to connect with some issues.
Jun 27 16:24:16 WAN_Connection: WAN(0) link up.
Jun 27 16:24:16 rc_service: wanduck 201:notify_rc restart_wan_if 0
Jun 27 16:24:16 custom_script: Running /jffs/scripts/service-event (args: restart wan_if)

That looks great. I'm new to Merlin, how do I get and install/schedule this script? I've changed out all the cabling so I'm just waiting to see if the fault comes back, but it would be good to have this in place.

Download, for example, putty - PUTTY

Enable ssh over LAN in the router interface and also jff scripts

Put the written commands into putty, of course first the IP and port in putty, then the login name and password.. - CHKWAN
