When I connect to any home Wi-Fi network in Router mode, connection is made but the DHCP address from home router obtained is completely wrong e.g it should be 192.168.15.xxx but is in 192.168.0.xxx range. (Router DHCP addresses to other devices correct.). So no Internet. In Cable mode, also 192.168.0.xxx, but works if I set address manually.
It is most likely a problem of your network. Someone has put another DHCP server in your network and issuing wrong IP addresses. This happens if you connect a router’s LAN to your network, which you should connect WAN.
