2.“DHCP:offer(192.168.0.1)”.
The DHCP server sent OFFER packet to acknowledge the previous DISCOVER packet. If the router did not receive OFFER packet, it usually means that there is something wrong with the WAN connection. For example:
1.The connection between the router and DSL/Cable modem is not cor- rect. Action: check the LINK status both on modem and the router.
2.The configured Host Name is not correct (for @Home). Action: double check the Host Name configuration.
3.Some ISPs register the router’s MAC address (for example, Me- diaOne). Only registered MAC addresses are allowed to access the Internet. Action: click “Copy MAC” button to copy the registered MAC address (older firmware reads “Clone MAC”).
