Don't use the WiFi for the connection. Use USB. See the linked article I gave below.
i have had my iPhone 4S connected to my laptop wifi which works good, BUT it keeps disconnecting for no apparent reason.
my laptop does have a problem in that it has always turned itself off, then back on again, a problem the techs tell me, its had since manufacture, but not using it often I did nothing about the warranty.
but even when the laptop is going, the wifi connection will disconnect.
Any solutions please??
