ITunes does not recognize my iPhone when I am connected to the internet!

Question

Okay, I am back with an old problem that I had with iTunes 9.0. iTunes will not see my iPhone if I am connected to the internet. If I turn off the WiFi, I am fine. Is there a fix for this? I found the following (see below) on 1 website and did all of them already. I don't have # 3, so I did not have to try that one thing.
Run through this series of potential fixes, which will solve sync issues for most users:
1. Reinstall iTunes. In some cases this issue can be resolved by completely removing then reinstalling iTunes as described in this Apple Knowledge Base article.
2. Remove third-party backup software. If you’ve installed software for an external hard drive or another device, it may include an automatic backup utility that recognizes the iPad as a storage device, interfering with the normal sync process. Try uninstalling any such software then re-syncing your iPad.
3. Remove iToner. It appears that the presence of Ambrosia Software’ iToner software may cause problems with syncing the iPad. Navigate to ~/Library/iTunes/iTunes Plug-ins and/Library/iTunes/iTunes Plug-ins (the Library folders inside your user folder and at the root level of your startup drive) and look for a file called iTonerSupport.bundle. Remove it, then restart, and check to see if iPad syncing occurs more quickly.
4. Delete iTunes .plist. Delete the following file
~/Library/Preferences/com.apple.itunes.plist then restart
