I look around in the standard Asus FW, and couldn't find it, maybe Merlin FW has the option? Thank you
 
See if you have this in SSH:

Code: 
 pwr config ...
           [--wait on|off]             : keeps CPU in sleep state without spinning
           [--ethapd on|off]           : Ethernet Auto Power Down Enable
           [--eee    on|off]           : Energy Efficient Ethernet Enable (all ports)
           [--dgm on|off]              : Switch Deep Green Mode Enable

No such settings in GUI. It may not survive reboot as well.

I need Merlin for SSH, right?
 
No, available in stock Asuswrt. Administration, System tab.

I remember Asus was disabling "wait" on some AX88U routers fighting with an issue. It was long ago though.

Thank you, can I add scripts with the standard Asus FW or do I need for that Merlin, apologies if this is a basic question

Thank you, do you know if this will survive a reboot?
 
It won't survive a reboot.

You don't need a script for testing. Change the value, test before you reboot. Unlikely to be related to your MoCA issues though.
Click to expand...
Understood, my script question was general question, no necessarily related, if I am able to create a persistent script without having to install Merlin
 
There is one option with usbmount, but I'm not sure if it still works with newer Asuswrt. @RMerlin knows if still usable or not. Otherwise no - no custom scripts with stock Asuswrt. I don't think you need this anyway for the MoCA issue you are trying to troubleshoot.

The usbmount script no longer works with stock firmware. Asus has removed it since their firmware didn't actively need it, and some malwares were using it to get launched at boot time.

Do you mean your new MoCA adapters? I would test related cabing first... temporaily setup some good patch cables (Ethernet and coax) and see if the issue persists.

The issues you described previously sound more like your ISP gateway has EEE enabled and it is not working right.

I am having these random disconnections in the WAN port (connected to the ISP gateway via a pair of MOCA devices over Coaxial cable), that I think (I might be wrong) are caused by EEE on the AX88U, then the MOCA device close to the AX88U reacting (by shutting down the ethernet link on the MOCA LAN port) to EEE with a disconnection on the LAN port, so it is kind of a self inflicted wound:

Sep 12 00:02:03 WAN Connection: WAN(0) link down.
Sep 12 00:02:08 WAN Connection: WAN(0) link up.
Sep 12 02:40:25 WAN Connection: WAN(0) link down.
Sep 12 02:40:35 WAN Connection: WAN(0) link up.
Sep 12 07:52:54 WAN Connection: WAN(0) link down.
Sep 12 07:52:59 WAN Connection: WAN(0) link up.
Sep 12 08:05:36 WAN Connection: WAN(0) link up.

I have disabled EEE on the AX88U to see if this changes, via SSH:

pwr config --eee off
PHY EEE (*) ==> Disable

pwr show

Power Management Configuration
WIFI Off Disabled
DISK Off Disabled
PCI ASPM Disabled
UBUS DCM N/A
CPU Off N/A
CPU Wait Enabled
CPU Speed Disabled
XRDP Gate N/A
NET Down Disabled
PHY Down Disabled
PHY EEE Disabled
PHY APD Enabled
SF2 DGM Enabled
DRAM SR N/A
AVS Enabled

I have done manual simulation of the situation by disconnecting the LAN port on the ISP gateway, and the WAN port on the AX88U, any manual LAN port disconnection on the ISP gateway is not detected in the logs of the AX88U, any manual disconnection on the WAN port on the AX88U is detected in the logs, therefore that means that the disconnections showing on the logs are not caused by the ISP gateway, the ISP gateway is connected using 2 MOCA devices via coaxial cable with the AX88U.

Perhaps when you leave the AX88U WAN connected to the near MoCA adapter, then that link remains UP no matter what upstream segment you disconnect... UP but no WAN/Internet.

Using the Screenbeam MoCA 2.5 adapters with my ASUS routers has been plug and play here.
