Please check the connection following these steps: 
1.  Is the connection between your PC and the router correct? 
The LED of Ethernet port which you link to on the router and LED on your PC's adapter 
should be lit. 
2.  Is the TCP/IP configuration for your PC correct? 
If the router's IP address is 192.168.0.1, your PC's IP address must be within the range of 
192.168.0.2 ~ 192.168.0.254. 
3.  Try the IP address 192.168.0.1. 
If the LAN IP of the modem connected with your router is 192.168.0.x, the default LAN IP of 
the  router  will  automatically  switch  from  192.168.0.1  to  192.168.1.1  (or  192.168.2.1  or 
192.168.3.1)  to  avoid  IP  conflict.  Therefore,  in  order  to  verify  the  network  connection 
between  your  PC  and  the  router,  you  can  open  a  command  prompt,  and  type  ping 
192.168.1.1 (or 192.168.2.1 or 192.168.3.1), and then press Enter.
