Cannot access LAN after Hibernating?

I have a problem with my laptop (Inspiron in sig). Each time I resume from Standby/hibernation, the computer tries to do a DHCP renew. However, it stays stuck at Acquiring network adress even though the DHCP server says it answered the request. The card is a Broadcom 440 10/100 Ethernet.

Tried it with both Dell's driver and Broadcom's drivers

Try typing ipconfig /release --> ENTER... then ipconfig /renew --> ENTER from a command prompt (Start | Run | Type cmd, and click OK), after resuming from standby. You may also want to check out this MSKB article...
