Camera IP now showing in Router


I am quite new to camera instalation. I have problem that my router is working only with simcard. For some time camera was working but then was disconected and after that my camera is not showing in connected devices in router and after i tried port forwarding in angelcam it shows that all ports are closed even that i opened port 554,8080,8090 and non of them work. Do you guys have any idea what can be wrong?
