Machine: Dell XPS17 laptop (702x) Windows 7 home premium Wifi adaptor: Intel Wifi Link 1000 BGN Router: Belkin F5D7634-4 802.11G Reconnection takes 3 or more minutes to establish after sleep. Tried all the on-line advice e.g setting power scheme to max power; unticking box in adaptor settings 'Allow computer to turn off this device'. Tried to update drivers for wifi adaptor but the update process says I have the latest drivers. However Dell's driver site analysed my laptop and says there is a later driver for download. Tried installing this but was stopped by message saying it wasn't authenticated/certified so terminated. Anyone had this problem, and how did they solve it?

Not unusual - sleep function has always been a pain in Windows. I gave up on it a couple of versions ago and judging by forum threads it is still a problem.
