@Fae After uninstall, reboot and install, the problem is still there. I also updated Java to version 8 update 271. Do you want me to send some log files? If so, which do you want?

@Fae To confirm, are you using the Omada Software Controller V4.2.4? Is it Windows or Linux version? Yes, I use Omada Software Controller V4.2.4 on Windows. I will reinstall the Software and test it.

TL-R605 not visible in Dashboard Speed test loops, after 240 it start again
