EVENT_NACK_LEASE

Question

I'm getting this error in the event log when trying to connect to the internet with my BEFW11S4 ver.4 router:
"Product: Windows Operating System
Event ID: 1002
Source: Dhcp
Version: 5.0
Symbolic Name: EVENT_NACK_LEASE
Message: The IP address lease %1 for the Network Card with network address %2 has been denied by the DHCP server %3 (The DHCP Server sent a DHCPNACK message).
Explanation
The DHCP Server service did not extend the lease on your computer's IP address, so your computer temporarily lost its connection with the network.
This could be caused by a scope change. For example, when a roaming laptop moves from one network to another, its IP address lease might need renewal. When the DHCP Client service tries to renew the address, that request might go to a different server that will not extend the lease either because it does not know about this address lease or because it has already issued the address lease to another client.
This also happens when two DHCP servers are configured to give out addresses in the same IP address range.
User Action
No user action is required. The DHCP Client service will continue trying to obtain a working IP address until it succeeds, and DHCP establishes the network connection on its own."
What is the proper action to take so that I may connect to the internet through the router?

Hi...
You can try releasing and renewing the IP address of your computer.
To release the IP address in the command prompt of your computer type ipconfig /release. This will set the IP address to all Zero's. At the command prompt again type ipconfig /renew.
You can also try by turning OFF and ON the DHCP server of the router. Login to the router configuration page. On the basic setup page you will find the Option that says DHCP server disable it. (In case if you are using an older firmware you will find a tab for DHCP).Save setting. Unplug the power the router wait for 30 seconds and then reconnect the power to the router. Again open the configuration page of the router and enable the DHCP server of the router.
Now try to connect to the internet.
