### alt text on Startup

When my system starts up, the internet connection is dead. This causes various problems with startup items such as updates and auto-start programs failing.

However, the connection is fine after going into Network and Sharing, Change adapter settings, then disabling and re-enabling the adapter.

**Any suggestions on why this is happening and how to fix it?**

System summary: Windows 7, 64 bit, Realtek PCIe GBE Family Controller, Linksys WRT610N router, Sci Atlanta cable modem.

UPDATE: Lately, the network connection for the system mentioned in this question is working about 80% of the time after startup. Have since updated to W7 SP1.
