A report states that flaws in DHCP (the Dynamic Host Configuration Protocol) resulted in some iPad's Wi-Fi problems. In order to facilitate the Wi-Fi connectivity, all the devices need to acquire an IP address from a DHCP server and these IP addresses come with an expiry date and generally majority of devices will try to renew their addresses in advance.

Commenting on the flaws attached to iPad , it has been established that in contrast with iPhone, the iPad's Wi-Fi connection remain active in its sleeping mode; holding the tablet with its old address and does not permit the tablet to renew its address in this state and this causes iPad to carry on the same IP address, even after waking up.

This can create in inconsistency in which one or more devices are sharing a common address will be kicked offline.

Further, it was found that Princeton University's connection problems occurred because of this default. 22 iPads out of 41 iPads recorded to be defective at Princeton, which compelled Princeton to take temporary advisory action against iPads. 8 iPads have been banned from the school network as a part of action taken by Princeton.

A suggestion offered to the iPads users involves, turning off an iPads Wi-Fi connection for few seconds, enabling DHCP to find out duplicate IP addresses and allowing DHCP to give a fixed address to an iPad beyond its range. Meanwhile it is also advisable to extend the DHCP lease time which can at least lighten this hurdle.
