Connectivity Issues
The iPad was designed to connect to the Internet over a wireless connec-
tion, so not having that connection can be frustrating. If you can't
connect, try the following:
Look for a connection indicator in the upper-left corner of the screen
( Figure 12.4 ). The Wi-Fi icon appears when you're connected to a Wi-Fi
network. If you're using a Wi-Fi-only iPad, the lack of the Wi-Fi icon
means you have no connection. If you're using a 3G iPad, as shown
here, the cellular 3G network is active when Wi-Fi isn't available.

On a 3G iPad, the network indicator icon and signal strength bars
appear even if you haven't paid for an active data plan. If the signal is
there but you can't get online, make sure you've activated a data plan,
or that you've not reached the limit of your data plan (see Chapter 1
for more information).
Try turning off Wi-Fi and turning it back on again. In Settings > Wi-Fi,
set the Wi-Fi switch to Off, wait a minute, and then set it back to On.
Similarly, try turning off the cellular radio on a 3G iPad and then turning
it back on. In Settings > Cellular Data, toggle the Cellular Data switch.
In the Wi-Fi settings, tap the Detail ( ) button next to the name of the
active network to view its advanced settings ( Figure 12.5 ). Then, tap the
Renew Lease button, which makes the iPad request a new temporary
IP address from the Wi-Fi base station.
