- Verify that the Ethernet card driver software and TCP/IP software are both
installed and configured on your PC or workstation.
- Verify that the IP address for your router and your workstation are correct and that
the addresses are on the same subnet.
Testing the Path from Your Computer to a Remote Device
After verifying that the LAN path works correctly, test the path from your PC to a remote
device.
¾ To test the path:
1. From the Windows toolbar, click the Start button, and select 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 as in the previous section are displayed. If you do
not receive replies:
• Check that your PC has the IP address of your router listed as the default router. If the IP
configuration of your PC is assigned by DHCP, this information is not visible in your PC’s
Network Control Panel. Verify that the IP address of the router is listed as the default
router.
• Make sure that the network address of your PC (the portion of the IP address specified by
the netmask) 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 PC, enter that host name as the account name
in the Basic Settings screen.
• Your ISP could be rejecting the Ethernet MAC addresses of all but one of your PCs. Many
broadband ISPs restrict access by allowing only traffic from the MAC address of your
broadband modem, but some ISPs additionally restrict access to the MAC address of a
single PC connected to that modem. If this is the case, you must configure your router to
clone or spoof the MAC address from the authorized PC. See the Mobile Voice HSPA+
Broadband 11n Wireless Router MVBR1210C Installation Guide.

the following:
• Date shown is January 1, 2000.
