U.S. Cellular® 4G LTE™ Router (LG2200D)

If the path is not functioning correctly, you could have one of the following problems:

• Wrong physical connections.

For a wired connection, make sure that the numbered LAN port LED is lit 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

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

• Wrong network configuration.

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

configured on your computer.

Verify 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 Windows Run window, type:

ping -n 10 <IP address>

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

If the path is functioning correctly, replies like those shown in the previous section are

displayed.

If you do not receive replies:

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

If DHCP assigns the IP configuration of your computer, this information is not visible in

your computer 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 different from the network address 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 could 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. Some ISPs additionally restrict access to the MAC address of a

single computer connected to that modem. If this is the case, configure your router to

“clone” or “spoof” the MAC address from the authorized computer.
