Connection Issue to a router

Has anyone experience this connection issue? If so how did you resolve it?
It can connect to the WiFi, however it won’t appear as online it show that it is offline and I cannot control it through LAN even the LAN control is on. I tried connecting through my friends WiFi it seems that it can connect to their WiFi no problem, as well as if it is connected through a mobile data it connects with no issue.
