Windows – How to fix network connection dead on startup, but okay after disable/enable

network-adapternetworkingwindows 7

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.

I had this issue on a friends machine. Seems to be a problem with some Windows 7 installs. The only "fix" I could come up with was to create a batch file with the following:

netsh interface set interface "Local Area Connection" disabled
netsh interface set interface "Local Area Connection" enabled

And have it run on Windows startup. (Replace the "Local Area Connection" with the name of the interface you want to disable/enable)

A little hacky, but it worked.
