obogobo,   I usually don't allow the computer to sleep, just hibernate when to battery gets low. When I wake mine, it would alwasy connect. Try these settings and see if it helps.   I usually do these tweaks on all the computers in my home.   Go to device manager(right click my computer, left click properties, left click hardware, left click device manager)  Go to the USB Controller section and click the + sign.  Go to each USB Root Hub and right click on it, left click properties, left click power management. Uncheck the box, allow computer to turn off this device to save power.  Restart your computer. -------------------------------------- Go to device manager(right click my computer, left click properties, left click hardware, left click device manager). Click on Network and then right click on your wireless adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.     Rick
Every time I close the lid of my Studio XPS 1645, Windows 7 enters sleep just like it should. The only problem is, when I wake it back up, I am unable to reconnect to any wireless network unless I either reboot, or disable and then re-enable the wireless adapter... it's extremely frustrating. This problem occurs when the computer resumes from hibernation as well. I have all wireless power saving modes turned off, both in device properties and under the power plan settings. The driver is current, I've tried both the most recent from Dell and a newer version from the Intel website to no avail. Any suggestions? Thanks
