A750 Wireless Dual Band Gigabit Router JR6150

For a wired connection, make sure that the numbered LAN port LED is on for the port to

which you are connected.

Check that the appropriate LEDs are on for your network devices. If your router and

computer are connected to a separate Ethernet switch, make sure that the link LEDs are

on for the switch ports that are connected to your computer and router.

• Wrong network configuration

erify that the Ethernet card driver software and TCP/IP software are both installed and

configured on your computer.

erify that the IP address for your router and your computer are correct and that the

addresses are on the same subnet.

Test the Path from Your Computer to a Remote Device

After verifying that the LAN path works correctly, test the path from your computer to a remote

device.

1. From the Windows toolbar, select Start > Run.

2. In the field provided, type:

ping -n 10

where <IP address> is the IP address of a remote device such as your ISP DNS server.

If the path is functioning correctly

, replies like the examples shown in Test the LAN Path to

Your Router on page 151 are displayed. If you do not receive replies, check the following:

• Check that your computer has the IP address of your router listed as the default gateway.

If the IP configuration of your computer is assigned by DHCP

, this information is not

visible in your computer’s Network Control Panel. Verify that the IP address of the router

is listed as the default gateway.

• Check to see that the network address of your computer (the portion of the IP address

specified by the subnet mask) is dif

ferent from the network add

ress of the remote device.

• Check that your cable or DSL modem is connected and functioning.

• If your ISP assigned a host name to your computer

, enter that host name as the account

name in the Internet Setup screen.

• Your ISP might be rejecting the Ethernet MAC addresses of all but one of your

computers.

Many broadband ISPs restrict access by allowing traffic only from the MAC address of your

broadband modem. If your ISP additionally restricts access to the MAC address of a single

computer connected to that modem, configure your router to “clone” or “spoof” the MAC

address from the authorized computer
