What is your ISP Modem model ?

ZTE ZXHN H288A

Agree with you Sentinel there is something weird with the INP values. However the line is very stable and for now I am only concerned with the 6 day reboot issue. Which is why I have put some settings back to default. And have to wait another 6 days to see if it has any effect , hehe ;-)

Disabled G.INP but adds 30ms to my latency due to ridiculous interleaved settings.

Also added pic of ISP modem, its on 35b profile which I cannot choose on the AC51. Purchased it before they switched to VDSL.

Switched ESNP to stable. Lower training speed as expected.
I think the INP settings are set (too high) by the DSLAM.

Some models have the option for ESNP under DSL Settings (enhanced sudden noise protection) is this ON ?

 

It’s on default through DLA. Have some noise spikes on the line.

Are you sure that it is VDSL (PTM) or should it be ADSL (ATM) as your synch / capped speed is low ? PPPoE / PPPoA Good luck with testing

I understand why you would think that ;-) See screenshot.
Very happy with the AC51 router so far, except for this reboot / memory leak issue.

The last to syslog entries just before it reboots after ~6 days.

Thanks Sentinel,

CRC is always 0/0 (capped VDSL line 5 MBit/3 MBit)
Never had it running for more than 14 days without a reboot, but the latest FW’s last only 6 days.
Must be some setting I use, or its just a firmware memory leak.
Have enabled 5G again and disabled time settings, will see if that helps first.

Under System Log – General Log and DSL Log, are the uptimes the same – I cannot remember but if the times are the same then probable as you say a Memory usage problem, caused by a service like wifi or AiProtection (if applicable) etc. Is the router doing anything special, like handling lots of wifi clients / VPN ?

 

Uptimes are the same, it just konks out every 6 days with around 4MB free memory.
The router load is light (2-4 clients) and I am almost running default settings. No VPN, no Telnet , no UPnP.
I am pinging the router every second over ethernet to keep my powerline adapter alive, but I assume this wont matter.

Thank you Sentinel & Asus, great update ! Curious to see if this FW will make it past 6 days uptime. Fingers crossed ;-)

Let us know how it goes

 

Still cant make it past 6 days without a reboot. Free mem drops to 4MB before each reboot.
Seems no one else has this issue ?, so I have enabled the 5G radio with default settings to see if that might help to get it past 6 days.

i am fix that problem. open telnet function connect via cmd console and type (top) and you can see which one process destroy your ram then you can close or stop that service :). by the way upnp service kill all ram almost using %80 ram. so i close upnp and re-open it’s fixed. @lostcause @uk-sentinel

 

Don’t have upnp enabled. Seems the firmware has a memory leak somewhere as all versions I tried reboots itself < 14 days. The current beta firmware I’m using reboots every 4 – 6 days runtime with upnp & telnet disabled.

When I try to update my ac51 to 1.1.2.3_805 it says that the firmware is invalid. And I try to update it straight from ASUSwrt

Went on fine on my AC51. Downloaded the file from the link a few posts back.

Please unzip the firmware file first then check the MD5 code.

As I understand it, you have zero/alot less errors with the ISP provided modem ?

Anyway  I have zero errors with my Asus on Broadcom exchange , 900m away.
