There have been Wi-Fi connection issues reported with the iPad. Some users reported that their iPads wouldn't connect to a
Wi-Fi network, while others noted that signal strength dropped off as
they moved
physically further away from a router.

On Monday, Apple posted an article for problems with the device not
reconnecting to wireless networks. Resolutions include updating router firmware and naming dual band networks differently. It is suspected that the problem however is in the iPad itself.
The current model of the iPad only connects to the Internet via a Wi-Fi connection. If problems continue, Apple suggests resetting the iPad's network
settings. iPad users can find those settings under the following file
path: Settings > General > Reset > Reset Network Settings.
They also suggest that the user move closer to the wireless router.
