Recently purchased (late June) Inspiron 545s.

OS: Vista 64bit Home Premium (all updates installed)

Network cable connection to Belkin Wireless G Router (NOT using wireless connection)

 

The internet connection randomly drops out then comes back (dropouts normally last for up to 1 minute).

 

I have a laptop running XP Pro connected to the same router that does not display this problem, so I assume the problem is with the Dell computer.

 

Troubleshooting steps I have taken:

Control panel - Network and Sharing Center says it cannot diagnose the problem.

 

I downloaded and installed the latest Vista64 network card drivers from realtek.com.tw.

 

Problem still occurs. Any ideas?
