Changing IP address in iPhone 4

I use Keynote on my MacBook Pro and I bought the Keynote Remote app for my iPhone. This works perfectly on my home Airport Extreme network. I teach at UMass and we have secure and non-secure Wifi networks. Both my iPhone and MacBook are on the networks, but they have different IP addresses.

Wifi support here suggests I change the IP address on my phone to the IP address on my laptop so that the remote will work. I cannot find how to change that. In the meantime, I'm going to try to change the IP address on my laptop to match my phone.

Any other suggestions would be welcomed. Thanks in advance.

iMac & MacBook Pro, iPhone4, iPad, Airport Extreme, Mac OS X (10.6.4)

To set a static IP address on your iPhone, go to Settings/Wi-Fi select the greater than sign ">" next to the network name you are connected to. Select the Static Tab. Enter the desired IP address, Subnet Mask, Router, etc. With the Static Tab still showing, select the arrow to return to the Wi-Fi screen.

Warning: Having 2 devices with the same IP address on the same network will cause problems.

Thanks. I have given up on trying to use my iPhone as a remote. I think the potential problems aren't worth it.

This is intentional. Each device on the network is meant to be assigned a different IP address.

The remote app works using Bonjour I believe - there should not be a need for both devices to have the same IP address.

Can you ensure that both devices are on the same wifi network - if one is one the secured network and the other is on the unsecured network the app's will not be able to communicate.
