Why does my internet connection shut off when I put my laptop to sleep? It happens every time it goes to sleep. Then I have to wait for it to find a connection when I wake it. How can I stop this from happening? Is there an easy solution for this? I am running windows 7 on a Compaq Presario CQ56 laptop. Thank you for your help.
Since your laptop is designed to frequently run on a battery as a portable device, rather than a docked station constantly connected to an electrical outlet, it needs a way to conserve power. The “sleep” mode is one such option, which puts the computer into a suspended state in order to save battery life. If your laptop’s network adapter is currently active, such as when you are connected to a wireless Internet source, then the battery will be drained at a faster rate.
The Windows operating system automatically turns off your network adapter when sleep mode is activated, and then turns it back on when you tap a key or press the touchpad. If you don’t want to have to wait for the Internet connection to be re-established when exiting sleep mode, there is an option to prevent your connection from dropping. Keep in mind however that this will drain the battery faster, so it isn’t recommended if you aren’t leaving your laptop plugged in while it sleeps.
To get started, navigate to the Start menu and locate the “Computer” button. Right-click the button and select “Manage.”
Click “Continue” if a prompt appears asking for your permission to open the window. Click the “Device Manager” entry located at the left side of the screen underneath the “System Tools” heading.
Find the “Network Adapters” option located in the list of entries at the middle of the window. Expand the entry by clicking the arrow button next to “Network Adapters.”
Right-click the name of your laptop’s network adapter in the expanded list of adapter options. For many laptops this will read “Atheros,” but there are other possibilities depending on your laptop’s brand and model. Choose the “Properties” option in the menu that pops-up on the screen.
In the “Properties” window, navigate to the tab labeled “Power Management” at the upper-right corner.
Remove the check mark from all three boxes that start with the words “Allow” and “Only Allow.” Click “OK” to save the change and then completely restart you laptop. Let the computer go into sleep mode and then tap a key to exit the mode. At this point your Internet connection should still be active without have to re-connect to your wireless router.
Depending on your operating system and network connection options, the Internet connection may still have dropped. If you continue to have the same problem, you will need to manually disable another network setting. Return to the Start menu and click the “Control Panel” button.
Open the green “Network and Internet” link located at the left side of the window above the “Hardware and Sound” heading.
Click the “Network and Sharing Center” link at the top of the new window.
Open the blue “Change Adapter Settings” link located at the left side of the window.
Right-click the entry for your wireless network connection and select the “Properties” option.
Locate the check box named “Internet Protocol Version 6 (TCP/IPv6)” and remove the check mark.
Click “OK” to turn this feature off and then restart your operating system again to prevent your laptop from dropping its Internet connection when sleep mode is activated.
