Desktop does not "sleep" after fibre optic broadband installed

This might be what you are looking for. Make sure you create a system restore point before installing a new driver then if it is no good you can easily get back to square one.

Where it says "Search Downloads" copy and paste this "Intel 82566DC Gigabit Network Connection". You should get to a page that looks like this:

Got fibre optic broadband installed by TalkTalk last week. Since then when I put desktop to Sleep, it goes to sleep but gets restarted by itself within a couple of minutes. It then continues to go to sleep and get restarted by itself. However, if the Ethernet connection between the router and computer is removed, the computer stays in sleep. I rang TalkTalk tech support and they say I need to update my network driver. Device Manager on my computer says the Network adapter is Intel 82566DC Gigabit Network Connection. I right-click that and select "Update driver software" and then "Search automatically for updated driver software", I get the message "Windows has determined the driver software for your device is up to date".

I am running Windows 7 Professional on Dell Dimension 9200. The router supplied by TalkTalk is DSL 3780 by D-Link.

Has anybody else experienced this problem? Help!

Thank you mitchell65 and SandeepP for your suggestions. But I thought of doing further digging on the sleep and awake aspect and came across this
Computer frequently wakes up by itself
In that thread one contributor mentions settings for the network adaptor which I followed as follows:
Start
Type "Device Manager"
Select Device Manager
Expand Network Adaptor
Right-click the card - in my case "Intel 82566DC Gigabit Network Connection"
Select Properties
Select tab "Power Management"
Uncheck "Allow this device to wake up computer"
OK

That seems to have done the trick.
