[Hareeshjoshi]

Hi i am using DSL-2750U WIFI router and this was connected to Cyberoam and whenever i want to connect this wifi the connection will be connecting but unable to connect inetrnet, If we put ip then only we can access internet, Even i checked whether DHCP is enabled or no, DHCP is enable.
Please help me from this issue.
