I use the router ER7206 V1 with a hardware controller OC300 V1. After upgrade to firmware version 1.4 from the previous firmware version 1.3 everything operates normally. The only problem I faced was an enormous number of event logs (not error logs) - more than thousand per 8 hours. I had to downgrade to previous version 1.3 and everything operates normally again - no useless event logs (DHCP server did that or that, numbered in thousands).

Please inform me how I could block these numerous event logs with the firmware version 1.4.

Thank You!
