I've been having problems with my wifi setup for a few weeks now. Mostly to do with random & quick disconnects/connects. My cable modem is bridged to an AC3100 router. There is also another ASUS router used as a repeater. It's been stable for over a year. When these disconnects happen, the lights on the modem & router stay on. I've adjusted settings on the router as suggested on this site. Today, the router randomly rebooted itself, all lights off. Firmware is 3.0.0.4.386_41700 Can somebody help interpret the system log for me? I'm assuming the May 5 dates are when it's in reboot mode and anything that happened prior on Feb 5 would tell a story. TIA

So, you have current/386 firmware... have you reset it and configured from scratch?

OE
 
No, I'm lazy. That's the next step this weekend I guess, when we're all not wfh. I've never done that when updating the firmware & things have been fine. Is there anything in the log that stands out to you?

No, other than it's restarting like you said... not normal, not right.

Here are some references... the reset FAQ explains how the factory default reset works and why it might be relevant, especially if you've upgraded from old 384 to new 386 firmware without a reset.

Reset FAQ
Reset Button/webUI Restore
WPS Button Hard Reset

A factory default reset is the first step to troubleshooting weirdness.

Also, disconnect LAN and USB connections and then add them back later, one at a time while observing the network... maybe the cat has chewed on an Ethernet cable.

Thanks. I'm confused by the following:

Factory default reset: before, or after flashing?
Since the goal is to use the NEW default values that are included in the NEW firmware, the factory default reset must be done while the NEW firmware is already flashed. Doing so before flashing will leave you running the OLD default values.

So if I'm understanding this correctly, once I've installed the latest firmware I then do the factory default reset?

Yes. Install, reset, configure from scratch. Do not restore an old/saved configuration since that would restore old defaults.

I prefer to do the webUI Restore with Initialize... it resets and also wipes logged data.
