BE92U Semi Random Issue / Loss of Web UI access / DNS failures / wifi drops

Hi All,

I finally got around to replacing my AC86U which was working nicely but no longer receiving updates and ended up replacing it with the BE92U. I updated the firmware to 3006.102.5 which was a PITA as the firmware upload would just hang and not proceed. Eventually, I got it uploaded using the Windows Sandbox Edge browser, Firefox and Edge would get stuck at the same upload window with no progress under the main OS. I did a factory reset afterwards and setup from scratch.

Now the issue that I'm running into every once in a while, I'll be browsing through the UI pages and suddenly get booted back out to the login page. I'll attempt to login again and get a login failure and eventually the captcha shows up. I'm using my password app to autofill the username and password so it's not me fat fingering that. I had setup SSH and could login to the device that way and that's where things get really strange. Running 'top' I see that the NTP is using 24% of the CPU. When I check the date command, I get back a date that is August 8 1946, a little while later it reports back Feb 22 1975. DNS lookups are not resolving either. I was able to pull back the syslog.log file and before I ssh'd in it shows Jan 22 as the date (not sure of the year). All during this period the wireless connection is dropping out and eventually I can get reconnected to the router via SSH.

I ended up having to reboot the router from the command line (Feb 22 11:25:07 syslogd exiting) and eventually everything comes back. The page which I was browsing into when it occurred last was the Advanced_VPNStatus.asp.

Noticing that the NTP went crazy and DNS lookups were failing I decided to use the IP address of the NTP server instead of the name as I remember running into weird issues back when I was using the RT-N66U. I'll look at putting it back to the name at a later time when the family isn't using the internet.

Not sure if this is a known issue or something new.

Log file is attached; things go haywire after Aug 14 15:33:06.

Similar issue from the day previous where the router date is messed up.
