Detected ARP Conflict on TL-ER605
Please help me with my concern. What does this means,
Module: Firewall | Level: NOTICE | Content: "detected ARP conflict and dropped 1 packets."
Module: DHCP Server | Level: NOTICE | Content: "DHCP Server allocated IP address 10.30.0.x"
TL-ER605 - IP: 10.30.0.1 , MAC: C0-06-C3-A8-07-C3
TP-Link AC1200 - IP: 10.30.0.4 , MAC: 10-27-F5-EB-F5-EA - ACCESS POINT
TL-WA855RE - IP:10.30.0.3 , MAC: B2-A7-B9-0C-43-D1 - WI-FI EXTENDER
Before I have no problem with this running for almost less than 2yrs then suddenly I found out that there is an error in system log, because we encountered no internet connection almost all of the workstation.
Also, we encountered no internet connection on Wi-Fi even the mobile device is connected (especially on Facebook Messenger: Waiting for Network status)
