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.
