Merlin 386.7_2 bug on AX68U: random reboot

[KattinVN]

Hi guys
My old router is AC3100 currently running 386.7_2 without issue
I decided upgrade it to Wifi6 so i choose AX68U, buy it from local store at china a few day ago
after received I flash merlin 386.7_2 but the router auto reboot randomly anytime ~every 1-3 hours

After few day check:

#1. Checksum SHA256 386.7_2 to verify file correct	still reboot randomly
#2. Check power line	still reboot randomly
#3. Factory default on webUI also tick "Initialize all the settings"	still reboot randomly
#4. Not setting anything on router, only set SSID and password	still reboot randomly
#5. Turn off setting on web interface i think it's the fault	still reboot randomly
#6. A whole day no device connect to AX68U	still reboot randomly
#7. Flash merlin 386.5_2 and factory reset	still reboot randomly
#8. Flash merlin 386.5 and factory reset/not change anything on setting	currenly testing
#9. Flash stock rom 386.49479 use same setting on merlin 386.7_2	work perfecly fine

I hope @RMerlin can find out the bug

This router is not very popular here on SNB Forums and has quite a bit issues reported:

ASUS AX68U 5GHz Band Dropping / Disappearing

Hi, I purchased a ASUS AX68U last week and am having a problem with the 5GHz band disappearing and all connections dropping. Initially set it up with separate 2.4GHz and 5GHz bands with some devices connected to each band. All of a sudden the 5 GHz disappears and no devices can connect to it...

If you can, return it and go for RT-AX86S or RT-AX86U instead. Both are better routers.

If the router is crashing then I'll need the crashlog entries from the system log.

The router does not look like it's crashed. The router was rebooted from the web interface at 14:24. Then it looks like the power was removed sometime after 14:30 and the power was restored at about 15:09.

Check the power supply for loose connections.

Or check the kids if they rebooted the system for reasons of their own...

If you're not using a saved backup config file from your old router to configure the RT-AX68U and a full (and proper) reset to factory defaults isn't giving you a stable network, the only conclusion is that the hardware is faulty. Return and buy another RT-AX68U (do not exchange it, the original return period will apply).

Here is what I would do to rule out user/firmware errors.

Wifi not secure after install 386.7.2

After installing v386.7.2 , I noticed that my 5ghz channel was unsecured. I was able to connect to it without a password. See the wireless networks in the image. My ssid's are ASUS-AEM-5, ASUS-AEM-6, and ASUS-AEM-2. There are two 5ghz channels. My main router is an axe11000 and I have two...

Your stated issues are not normal on any of the many RT-AX68Us I have set up for my customers. There is nothing for RMerlin to 'find out'. 386.7_2 works extremely well.

i think because i using model from china maybe it different model US, so the rom merlin not compatible because i run stock rom it perfectly fine

I don't think that is it.

As others told you, there no crash there. First time it was explicitly rebooted from the webui:

Aug 27 14:24:26 rc_service: httpd 1009:notify_rc reboot

And second time since there is a significant time gap, the most likely reason is a power outage, or the router was turned off/unplugged.

A crash would have generated log entries.
