- Make sure the Modem’s IP address matches the IP address previously stored into the
Modem’s configuration. You must have previously set the Modem’s Ethernet IP address
and subnet mask, saved the Ethernet configuration changes, and rebooted the Modem
for the new IP address to take effect.
- Make sure the PC and the Modem are on the same IP subnetwork or the target router is
reachable through a router on your LAN.
- Make sure the TCP/IP properties setting is correct in your PC.
12.4 Problems when accessing the Internet or remote network
1. Cant’s access the Internet or remote network
There are four possibilities to causes this problem
1. The connection between the computer and the Modem
2. The connection between the Modem and your NSP
3. The connection between your NSP and your ISP
4. The connection between your ISP and the Internet
To isolate the problem, you can verify IP connectivity with following steps by running a
ping <IP address> command. For example, ping 192.168.0.1 .
1. Ping the IP address of your PC. If you get a response back, proceed to next step
directly. If you don’t get a response back, check that:
- The network adapter card is installed.
- The TCP/IP protocol is installed.
- The TCP/IP protocol is bound to the network adapter.
- You’ve correctly set the IP address of your card.
2. Ping the IP address of your Modem. If you get a response back, proceed to next
step directly. If you don’t get a response back, the problem lies between your PC
and your Modem:
- Check the cables.
- Check the hub.
- Make sure that your PC and your Modem belong to the same IP sub network.
- Observe the TX and RX LEDs to see if data traffic flow appears to be normal
3. Do you have a connection to your ISP. Check the status for your WAN interface
(ppp-0). It should show a valid IP address for the interface. If it shows 0.0.0.0 then you aren’t
logged into the ISP.
i. Check your account username and password.
ii. Try the ‘bt_test@startup_domain’ test account
(password can be anything you want).
4. Ping the WAN address of the router. If you don’t get a response back then the
problem lies in the routing table in your PC or in the router:
iii. Check that you have the correct default
gateway or router address set-up in the TCP
settings of your computer.
