Can't connect to internet when Vista computer wakes from sleep

When your Computer goes into Sleep Mode, you can wake it by shaking the mouse. If you have Wake on LAN set up, you can wake it up from another location, by dialing in to it.

putting a computer to sleep is not the same as hibernation because sleep mode still is technically powered on it's just in a relaxed state or low-powered state whereas hibernation takes everything that's in Ram writes it to hard drive and then completely Powers down hope that helps

Best way to restart it from wake up is remove the battery (if it is a laptop) or push the power button for at least 10 seconds (or more) until you can't see any lights at all or any sound from the hard drive. That is the only way you can restart the computer if it is not waking up from sleep mode.

I'm not sure what is your problem the WOL or no connection icon after sleep

If the computer goes into sleep mode, some devices won't wake afterwards. As a test, either disable sleep mode, or open Device Manager, find the adapter or its USB port and set the power properties to not allow the device to turn off to save power.

Click on Start, Control Panel, Network Connections, Right click on local area connection that is connected and click properties
Under networking tab, click configure. New window opens, then click on last tab power management, take check mark out of "Allow this device to wake the computer" then click "OK"

When you have access to windows, go to control panel and select Power options and change to time windows puts the monitor to sleep. You can set it so the monitor from a couple of minutes to never goes to sleep. This might help your problem.

One possibility is if you have an optical/laser mouse that is on a relective surface and the mouse light is reflecting and triggering the computer to think that there is activity.

More than likely, your network card is keeping your computer from staying in sleep mode as any internet data activity is taking the computer out of sleep mode making the computer think there is activity.

There is an option in the Network Adapter properties that says to "Allow this device to wake up your computer"

Go to Control Panel and click Classic View on the left hand side

Double Click the Network and Sharing Centre Icon.

On the left hand side of the window that opens, click Manage Network Connections.

Right Click on the connected Network Connection. It is probably the Local Area Connection. Right click on it and choose Properties

A new box will open up. Click the Configure button under the Connect Using: box

Click the last tab at the top that says Power Management.

Under the Power Management tab click the square box that is beside: Allow this Device to Wake the Computer to take the checkmark out of the box. Then Click OK at the botton and close all the windows.

Let the computer go into Sleep mode and see if the computer still comes out of sleep mode on its own.

Let me know if this worked for you,

I'm out for the evening, but I'll be back tomorrow morning. Leave the info and I'll get you a solution.

Go into BIOS and find the wake on LAN option and turn it off.
otherwise check via configuration and select properties of your network card and check if wake up is checked. Ifso, uncheck it and restart.
