-
Verify that the IP address for your router and your workstation 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.
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 computer has the IP address of your router listed as the default router. 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 router.
•
Make sure that the network address of your computer (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 computer, 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 computers.
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 computer connected to that modem. If this is the case, you need to configure
your router to clone or spoof the MAC address from the authorized computer.
Problems with Date and Time
The Email screen displays the current date and time of day. The Mobile Voice HSPA+
Broadband 11n Wireless Router uses the Network Time Protocol (NTP) to obtain the current
time from one of several network time servers on the Internet. Each entry in the log is
stamped with the date and time of day. Problems with the date and time function can include
the following:
•
Date shown is January 1, 2000.
Cause: The router has not yet successfully reached a network time server. Check that
your Internet access settings are configured correctly. If you have just completed
configuring the router, wait at least 5 minutes, and check the date and time again.
