Section 11 - Troubleshooting
Symptom: Router cannot obtain an IP address from the ISP.
Recommended action:
1. Turn off power to the cable or DSL modem.
2. Turn off the router.
3. Wait five minutes, and then reapply power to the cable or DSL modem.
4. When the modem LEDs indicate that it has resynchronized with the ISP, reapply power to the
router. If the router still cannot obtain an ISP address, see the next symptom.
Symptom: Router still cannot obtain an IP address from the ISP.
Recommended action:
1. Ask your ISP if it requires a login program — PPP over Ethernet (PPPoE) or some other type of login.
2. If yes, verify that your configured login name and password are correct.
3. Ask your ISP if it checks for your PC's hostname.
4. If yes, select Network > Internet > WAN1 Settings or WAN2 settings. Select DHCP as the Connection
Type, and enter the Host Name of your ISP account.
5. Ask your ISP if it allows only one Ethernet MAC address to connect to the Internet, and therefore
checks for your PC's MAC address.
6. If yes, inform your ISP that you have bought a new network device, and ask them to use the firewall's
MAC address.
7. Alternatively, select Network > Internet > WAN1 Settings or WAN2 settings. Under MAC Address
section, choose Clone your PC's MAC as the MAC Address Source.
Symptom: Router can obtain an IP address, but PC is unable to load Internet pages.
Recommended action:
1. Ask your ISP for the addresses of its designated Domain Name System (DNS) servers. Configure
your PC to recognize those addresses. For details, see your operating system documentation.
2. On your PC, configure the router to be its TCP/IP gateway.
