An ad-hoc network allows you to connect an iPhone to your computer. The setup process is relatively simple but sometimes complications can occur related to software incompatibility and improper configuration. When the ad-hoc connection is not set up correctly, your iPhone does not recognize or connect to the network. Ad-hoc networks generally represent a temporary type of network, and the risk of a security breach increases with this type of network.
Firewalls protect public and private networks by preventing unauthorized access to a network. Before connecting your iPhone to an ad-hoc network, verify that the configuration of the computer’s firewall will accept the iPhone. A firewall’s settings can prevent wireless devices from connecting to the computer. This prevents the iPhone from connecting to the computer’s ad-hoc network. If your iPhone does not connect to the network, temporarily disable the firewall to determine if it is the cause of the connection problem.
Connection problems can occur if the Wi-Fi module on your iPhone and the computer are not compatible. Determine the mode used by both your iPhone and computer. The mode is the 802.11 number. Make sure the letters following the numbers match. If they do not match, try using a different Wi-Fi channel. If this does not work, you may need to use an access point such as a Wi-Fi router to connect your iPhone to your computer.
Establishing a Connection
After setting up the ad-hoc connection, verify if the DNS IP of your computer is empty or different from “68.28..”. An empty or modified DNS IP means the DHCP did not work. Further, if the name of the ad-hoc network does not show up on your iPhone, the connection was not properly established. Tap the “Forget This Network” on your iPhone. Once your iPhone indicates the connection was dropped, attempt to connect to the ad-hoc network again. If the iPhone still won’t connect to the network, try deleting and recreating the ad-hoc network from your computer.
When you set up an ad-hoc network, you have the option to make the network public or private. Any security measures implemented can create conflict when connecting your iPhone. Wired Equivalent Privacy, Wi-Fi Protected Access and WAP 2 are security protocols supported by the iPhone. Conflict occurs with the security protocol if the ad-hoc network uses a different security protocol not supported by the iPhone.
