Hello everyone.

Recently I purchased an ER605 v2 router, but unfortunately I encountered an issue with it - Internet drops out every 10 minutes or so. My network setup is Fiber optic - ONU terminal from the ISP - ER605 v2 router - Desktop PC. Everything works fine on my old router and the Internet connection is stable.

What I've tried so far:

• every firmware version since 2.2.3
• disabled Load Balancing
• disabled Enable Application Optimized Routing
• configured manual Online Detection using ping to 1.1.1.1
• set Online Detection to be Always Online

but to no avail, the problem persisted.

For some reason the log file cannot be uploaded here, so here is a snippet of the logs:
