Windows 7: Resuming from sleep...

...will not connect me back to internet.
It just says unidentified network and no internet access, solution is to disable and enable my adapter but it gets quite annoying.

I've noticed this before on my bro's laptop but solution to stop it from happening was never found.

I got asus P5Q-Pro p45 chipset and my card is
"Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller(NDIS6.20)" Yep, copied it from device manager .

This problem is recent, been running windows 7600 professional x64 for some time but never had it happen before on this computer, since now.

I haven't really done anything that could affect it, no new drivers, well nothing related to networking at functionality level... except 1 thing from bios.
Changing sleep mode to s3 which I believe is default because everything shuts down, except ram and that stuff to keep it alive.

Obviously, I'm going to try turning it off.
I believe this is not even rare case but I've not seen much discussion on this so... yeah.

I found this

Helpful, but no instructions of WHERE in the bios to look
Yes - it's happening to me too

I went into power options and switched sleep mode off.

1. Open the Start Menu, and type powercfg.cpl in the search box and press enter.

Then just change the "plan" to "never" for sleep/hibernate mode.
I also made sure the display didn't go off after 10 mins.
