Almost every time I wake up my MS Vista desktop computer (with all updates,
SP2+) from the sleep mode (S3) I get a "Local Only" connection, so I cannot
use the Internet until I reboot the computer or reset the network card (or
ipconfig /release / renew).

I can see the following entry in the system log every time this happens:

---
Event Details
Product:
Windows Operating System

ID:

EVENT_FAILED_TO_RENEW

Message:
Your computer was not able to renew its address from the network (from the
DHCP server) for the network adapter with MAC address ###. The following
error occurred:
###. Your computer will continue trying to obtain an address on its own from

What should I do in order to solve this problem? I've tried many things like
disabling the power management for the network card or resetting the Windows
Firewall but none of them worked.

Thank you!
