b. Verify that the attached switches or PCs are connected to LAN interfaces on the device, and verify that the LED for each interface is normal.
2. Verify external network connectivity.
Connect the external network broadband cable to the PC, set the PC according to the network access method provided by the carrier, and check the external network connectivity.
¡ If the PC can access the external network normally, the external network broadband cable is connected normally. Proceed with the following steps to resolve this issue.
¡ If the PC cannot access the external network, contact the carrier to check the external network broadband.
3. Verify that the network access settings of the device are correct.
According to the network access method provided by the carrier, check the network access settings:
¡ When the external network connection mode is DHCP, identify whether the external network IP address is on the same subnet as the internal network IP address. If they are on the same subnet, modify the internal network IP address.
¡ When the external network connection mode is fixed IP, verify that the external network IP address, subnet mask, gateway address, and DNS server IPs are configured correctly.
¡ When the external network connection mode is PPPoE, verify that the account and password entered for network access are the same as those provided by the carrier.
4. Identify whether invalid DHCP servers exist on the internal network.
Identify whether the IP address of the PC that cannot access the external network is assigned by the device and whether the gateway address of the PC is correct. If the IP address obtained by the PC is not assigned by the device, it means that invalid DHCP servers exist on the internal network. To resolve this issue:
¡ If switches on the internal network support DHCP snooping, enable DHCP snooping on these switches to deny invalid DHCP packets.
¡ If switches on the internal network do not support DHCP snooping, manually locate the invalid DHCP servers and remove them.
