If you're thinking of connecting your iPhone and your computer
to a public wireless access point to transfer files from computer to
iPhone - forget about it. Most public access points try to protect
everybody's privacy by forbidding any peer-to-peer communication. Each
of your devices will be able to access the Internet, but most likely
they will not be able to communicate with each other.
This leaves you with another option - creating your own WiFi network.
Creating WiFi network with a WiFi router. Please consult your router documentation on the exact procedure, but keep two things in mind:
some routers block peer-to-peer
communication by default, preventing your computer and your iPhone from
being able to communicate with each other directly, so you will have to
check for a setting that blocks such communication. Such setting may be
called something like L2 Isolation or some other isolation. Please consult your router documentation for more details.
some routers offer wireless connection
for wireless devices, and Ethernet (cable) connection for your computer.
Such routers will often block direct communication between your
computer (connected by a wire) and your iPhone (connected wirelessly).
Please consult your router documentation for more details.
Creating computer-to-computer ("ad hoc") WiFi network directly from your computer, without any router.
On Windows Vista or Windows 7 computer open the Start menu and select Control Panel:
Select Network and Internet:
Select Network and Sharing Center:
Select Manage wireless networks:
The dialog box will appear. Select Create an ad hoc network:
Skip the introduction screen:
Make up a name for your network and enter it in the Network name field. Select WEP in the Security type drop-down box (this is important!!!). Make up a password consisting of 13 ASCII characters (this is important!!!) and enter it in the Security key field. Check the Save this network checkbox on Windows 7 (or Start this connection automatically checkbox on Windows Vista). The dialog should now look like this:
The newly created computer-to-computer (ad hoc) network now should appear in the Manage Wireless Networks window that you opened earlier:
You're done now. The network should be functional at this point.
note that if your computer was connected to Internet via WiFi (via a
WiFi router or via some public access point), you will loose this
connection after creating your own computer-to-computer network, because
your computer can't host a WiFi network and be connected to another
WiFi network at the same time using the same WiFi card. So if this is
the case, you may want to reconnect to that other WiFi network that you
were using to access the Internet after you're done transferring files
Note on repeated usage of the same ad hoc network (doesn't apply to the first time when you're creating this network): If you checked the Save this network checkbox
on Windows 7, you will still see this network after rebooting your
computer, but it will be inactive. To activate it, you have to connect to
it in terms of Windows (while in fact your computer will be re-creating
this network rather than connecting to it). To connect to it, bring up
the network connection pane (by either clicking on a system tray icon
marked with red arrow on the following screenshot, or by going to Control Panel, Network and Internet,Network and Sharing Center and selecting Connect to a network link). On this connection pane find your network, click it, and then click the Connect button:
