Make sure the laptop is not going into standby mode when left unattended or when the lid is closed. Look under power management settings in control panel. This would usually knock out the wireless. Also let windows manage the wireless if you know how to set up your own WEP/WPA
Just get out there and ride. The Peak, Dark or White is bloody brilliant and its on your doorstep if your in the Derbyshire/South Yorks/Cheshire area. I love hitting the Roman Road and shitting myself down 'The Beast'!
