Asus RT-AX88U Pro stopped working occasionally

[David Cavalli]

Saw a similar thread with an RT-AX86U with Merlin, but that seemed to resolve to a USB issue. My RT-AX88U Pro is a few months old, but has been relatively stable along the way. For the past few weeks, I've had stability issues. At first, I thought it was related to my cable modem. I replaced it, when ChatGPT said my CM1100 values were heat related, so bought an Arris S33 to resolve the problem. It didn't. My internet unreliability issues look much more likely to be my 88U Pro now. I just had another outage now at 4:24 PM. No ping, ssh, http or any other access to the router. The Wifi light on the router seemed to be off. No deviced wired or wifi had connection to the router. Local connections (i.e. NAS) access was gone. *NOT* an internet issue (i.e. Arris, Cox, w/e). Looking at the log, there seem to be "Invalid device mode -1" lines which looks like something internally is failing.

I saw the other user copy/paste the system log to request help. I'm posting my own fresh down / reboot syslog here to ask for any feedback and/or help. All URL and addresses for VNC were globally replaced for privacy, but can be sent directly if that is somehow necessary. (i.e. Update forced for alias myvncaddy.vnchome.com, new IP# 99.99.99.99 not the right info, but find/replaced.)

Services used was asked. Here's a list of the customizations I can think of from memory:

• profile.add - personal profile cfg
• hosts.add - personal hosts file cfg
• dnsmasq.conf.add - personal mapping MAC to local IP
• smb.postconf - fix SMB directory permissions
• amtm - latest installed but no services currently used
• usericon - custom .log icons for <MAC> devices, same for last few Asus routers
• DDNS service - configured my VNC address
• have an authorized key for SSH access

Thanks in advance!
