I cannot access the router's Web User Interface.

Solution 1:

Make sure that the power cord and all the Ethernet cables are connected correctly. This includes the cables connecting the Wireless Router and all the computers.

Solution 2:

Make sure that your computer is using an IP address that is within the default range of 192.168.2.xxx. Make sure the address of the subnet mask is 255.255.255.0. The Default Gateway should be the IP address of the Wireless Router, which is 192.168.2.1.

Solution 3:

Verify the connection setting of your Web browser and that the HTTP Proxy feature of your Web browser is disabled. You need to do this so that your Web browser can read the configuration pages inside your Wireless Router.
