Thanks a lot. Is there any workarounds to avoid the issue? Probably to disable any services or change config...

Hi all. After updating FW to 3.9.3 (stable) my Keenetic Ultra starts to completely stop working. I have some error messages in log (located on syslog server). After that I can see all services become unavailable: first of all WUI and cli than DHCP than Wifi than Internet access completely. I tried to remove entware USB-flash and change Ping checker config, but without any success. Reboot fix the problem for some time: it works good from dozen minutes to several hours and than stops again. Any ideas? PS. I haven't tried to reset to factory settings yet.
