Data test problems
The following section addresses questions about Data testing.
Issue
The IP ping menu says pings are being sent, but the network statistics are not incrementing.
Resolution
Verify that the network is up by checking the Frame LED. It should be solid green.
Verify the IP address and netmask.
You may be behind a firewall. Use trace route to determine whether this is the case.
The IP ping function only attempts to send a ping every second. Depending on certain conditions,
a physical ping packet may not be sent.
If IPoE or PPPoE data mode is being used, the device has to ARP the address first. If this fails even-
tually you will see a ARP HOST UNREACHABLE message. Check to see that the destination IP
address and your configured IP parameters are correct.
If the Ethernet interface is being used, make sure that the cabling is correct. If the Ethernet cable is
not hooked up, or is hooked up incorrectly, a packet will not be sent. Thus the Ethernet statistics will
not increment.
Issue
The Sync LED is green, but the Frame LED status is not.
Resolution
Verify that the Data Mode is not set to None.
Issue
In through mode, I’m connected to the Ethernet connector, but I’m not getting a data connection
(green Frame LED).
Resolution
Go to the Ethernet Settings screen and check the Media Type. If it’s set to Auto, change it to match
the specific LAN speed and duplex type that you are using.
Issue
I’m on an ADSL circuit and the ATM results indicate that I am receiving frames but the Frame LED
is not green and IP pings are not working.
Resolution
Check the encapsulation and the mode. The wrong protocol may be in use.
Issue
I’m on an ADSL circuit and I have a PPPoA service and I get a PPP TIMEOUT message
Resolution
Verify that the VPI-VCI is correct.
