@Marvin_S thank you for the information. Does it mean i can only connect remote if i had a public IP adress? Because i can connect to my Router remote over "Tether" app but not via browser.

@Marvin_S Hi, thank you. can i also do this remote or only on site?

Hi, i have a very high data consumption in my network. is there a oportunity to chek the data consumption per IP Adress so i can check which device had the highest consumption?

any hints how to solve my problem?

@Sunshine Even after the update, the DHCP problem still seems to be present. What could be the reason?

@Sunshine Hi, my FW version is 1.2.0.0.9.1 v0001.0 Build 200511 Rel. 44954n. I think the router is otherwise good, but the DHCP server must run reliably and stable.
