This problem has surfaced recently. After I switch on my laptop from hibernate/sleep mode, it can't connect to the Internet. It displays all the available networks (wireless) but it never succeeds in connecting to the Internet. It is able to connect to the router though.

I tried many other solutions like disabling windows to turn off the adaptor, but none of these are working.

Additional info:

This problem persists on both wired and wireless. Rebooting will solve the problem until next sleep/hibernate. I am not sure about BIOS, but I had updated windows and drivers recently. Mine is a Dell Latitude E6410 laptop

Something to try- You can right click your network card under device manager, look for a power management tab that talks about turning off the device to save power. "allow the computer to turn off this device to save power" and untick it since you have an issue

also it's worth pointing out that under control panel - network connectinos, you can right click your LAN icon and click diagnose, whenever there is a problem. that can "fix" it quicker than restarting (I tend to set it to DHCP(the default) when doing that).

After waking from hibernation or sleep the router will still be available though the connection would not be able to connect but will show connected (though you wouldn't be able to use internet using any browser or download manager). What you need to do is to disconnect and then reconnect again, it will reconnect( could take some time maybe 1 min more than usual ). After this you would be able to use internet again without any problems concerning the hibernation. You need to do this after every hibernation although if your computer is on sleep mode and you wake it after some time (less than 30 mins after sleeping) then you needn't do it again.

What works for me with my wired connection: Unplug router, then put windows 7 (32) machine to sleep. When you're ready to go back to work, simply reverse those steps: wake up machine, then replug router. It may take 30 seconds or so once the router shows that it is alive.
