U.S. Cellular® 4G LTE Router (LG2200D)
Erase the Current Configuration Settings
You can use the Erase button to erase the configuration and restore the factory default
settings. You might want to do this if you move the router to a different network. You can also
use the Restore Factory settings button on the router to erase the configuration and restore
the factory settings. (See Factory Settings on page 120.)
¾ To erase the configuration settings:
1. Log in to the router.
2. Select ADVANCED > Administration > Backup Settings.
3. Click the Erase button.
The factory default settings are restored. The user name is admin, the password is
password, and the LAN IP address is 192.168.0.1. DHCP is enabled.
Static Routes
Static routes provide more routing information to your router. Typically, you do not need to
add static routes. You must configure static routes only for unusual cases such as multiple
routers or multiple IP subnets on your network.
As an example of when a static route is needed, consider the following case:
• Your primary Internet access is through a cable modem to an ISP.
• You have an ISDN router on your home network for connecting to the company where
you are employed. This router’s address on your LAN is 192.168.0.100.
• Your company’s network address is 134.177.0.0.
When you first configured your router, two implicit static routes were created. A default route
was created with your ISP as the gateway, and a second static route was created to your
local network for all 192.168.0.x addresses. With this configuration, if you attempt to access a
device on the 134.177.0.0 network, your router forwards your request to the ISP. The ISP
forwards your request to the company where you are employed, and the company’s firewall is
likely to deny the request.
In this case you must define a static route, telling your router that 134.177.0.0 should be
accessed through the ISDN router at 192.168.0.100. In this example:
• The Destination IP Address and IP Subnet Mask fields specify that this static route
applies to all 134.177.x.x addresses.
• The Gateway IP Address field specifies that all traffic for these addresses should be
forwarded to the ISDN router at 192.168.0.100.
• A metric value of 1 works because the ISDN router is on the LAN.
• Private is selected only as a precautionary security measure in case RIP is activated.
