My laptop is terribly slow when I wake from sleep or hibernate. I found that if I turn off the wifi before I sleep it is much faster when resuming from sleep. Is there a way to turn off wifi before sleep/hibernate. I am using Windows 7 as my operating system.
Go into Device Manager, find the WiFi adapter, look at its Properties, and see if it has a Power Management setting similar to "Allow the computer to turn off this device to save power". Make sure that's checked.
Also, find your brand-specific "Control Center" or whatever, and see what Power Management features it has -- there may be an option there.
If you want to check the group policy issue and you have local admin authority try running gpedit.msc and looking in the location described below
In situations where you need for users to receive software, implement folder redirection, or run new scripts in a single logon, apply a GPO with the setting Always wait for the network at computer startup and logon to the computer. This setting is located under Computer Configuration\Administrative Templates\System\Logon in the Group Policy Object Editor. For this setting to take effect, Group Policy must be refreshed or the computer restarted.
