I have a D-Link DWA-552 in my desktop. When I awake my computer from sleep mode, my computer is no longer connected. I try to reconnect and it wont do anything. I have to restart the computer to be able to connect again.Win7 64bit.

If you do a quick search of the forums for sleep mode, you'll see that letting the computer go to sleep is a bad idea. Until the issue is resolved, it is best to avoid it altogether.

But there was not that issue in the Beta. Why the back-step???? RC took alot of steps back from the Beta-WMP is not as cool, compatability issues with MSFT products as well as other software.

Hi,y don't u try to change the power management settings of the network adapter.device manager -> right click on network adapters and click on power mgmt.uncheck the option that says allow this device to wake up the computer.if there is no network activity then itmay not come back from sleep.try that. excuse me if the logic is wrong

Yeah, i had already messed with the power options and set my network card to always stay on (though it worried me cuz it increases my chances of getting a virus or something), but didn't do anything. Guess I just wont let my computer go to sleep.

I am having a similar issue. I generally close my lid on my laptop and let it sleep, but sometimes when switching on in the morning again, no network. If I go to the adapter, it shows that it is working, but network center shows it is disabled. I tried to reboot but then logged me in on a temp profile as the network was still down. I even tried changing power profiles on the adapter and drivers. This morning the same happened. Walked away and about 5 minutes later it suddenly worked. So far this is the only major problem I am having. And this has only started in the last week. Been running 32 bit RC build 7100 now since May the 7th.
