Using PPPoE and Windows XP, you may notice a slight hang after startup when you try to initiate a PPPoE connection. This is due to Windows XP trying to get an IP for your NIC. To avoid this:

1. Goto Network Properties
2. Select your LAN NIC
3. Manually set the IP address

This won't affect your DSL connection, and will remove this annoying 30-120 second wait.

Hope this helps.
