TL-R605 issuing same IP address to mulitiple devices (including OC200 controller)
Since a few days, my router suddenly starts assignming the same IP to different devices on my LAN.
As a result, my access points lose connections regularly (~once per hour at the moment). The OC200 controller managing the setup is not accessible through local IP because its IP address is wrongly mapped to another device. Therefore I cannot check the router configuration or perform any debugging. Through Omada cloud, I cannot access the router configuration because it only let's you monitor the ports. There, even the switch is not visualized (I expect for the same reason) and the network topology is broken, as a result.
Hardware setup
1 TL-R605 VPN router
1 TL-SG2008p switch
3 EAP245 (PoE powered)
1 OC200 Omada controller
Firmware versions are up-to-date, however because OC200 is not accessible I cannot report versions.
The days before the issue started, I got regular notification from the OC200 that the maximum number of log entries had been reached. Apparently this is just a notification but should not be problematic for normal operation.
What I tried:
- reboot all hardware
- remove as many LAN connections as possible to avoid any duplicate IP assignments
- replace the OC200 USB stick for storage of backup and logs
