Windows 7: Wifi connectivity lost after sleep mode

Wifi connectivity lost after sleep mode

Hello Friends,
I have Windows 7 on a Dell Inspiron 1545. Most of the time when I put my laptop to sleep and restart it Wifi network connectivity is lost and I have to click the 'Wifi Signal' icon in the system taskbar and click on my network name and click connect to regain connectivity. I have gone to 'Power Management' tab and cleared 'Allow Windows to turn off this device to save power' option as suggested by most posts but it has done nothing to help me. But sometimes even after a long sleep the laptop immediately connects back to the network and sometimes even if I just close the lid and open it after a few seconds network connectivity is lost. Please help.

Windows 7 Ult, Windows 8.1 Pro,

Going into device manager and unchecking the power saver on the adaptor itself has fixed this problem in the past. Or maybe putting check marks in both places will help, hard to say because they all react different to this adjustment.

It's considered to be a driver problem so updating or finding a better driver for your network adaptor might help but unchecking the power saving feature can also work.

I have unchecked the box in the power management box but that doesn't help. I have also updated the drivers. I will try updating again.
