How do I remove a computer from Wi-Fi syncing

Question

I have an ipad which was set up to sync via WIFI to a Dell laptop I had when I bought the ipad.  That laptop was failing so I purchased a new one (another Dell) and somehow when I set up the new ITunes, the ipad somehow got confirured to sync to the old laptop for Apps and Podcasts while the new one is configured to sync for Books and Tones.  I cannot figure out how to remove the old laptop from the Itune WFI Sync and add the Apps an Podcasts to the new laptop.  I did unchceck the Sync to this laptop with the ipad connected to the old laptop but that did not result in any change on the ipda in the general setting>iTUnes Fi-Fi Sync screen.  I would appreciate any help anyone can offer
thanks

These instructions are given under the assumption that your entire iTunes library is now on the new computer.
On the old laptop, launch iTunes and go to Edit>Preferences>Devices and check the box that says "Prevent iPods, iPhones and iPads from syncing automatically. Click OK and quit iTunes. Now connect the iPad to the computer with the cable and launch iTunes. Select your iPad under the devices heading. Click on the Summary tab. Uncheck the WiFi sync option and click on Apply. Then remove the iPad from the computer and quit iTunes.
Restart your computer and then launch iTunes. See if the iPad shows up under devices and also check the settings on the iPad to see if that computer is no longer listed.
On the new computer, just select the apps that you want to sync to the device in your sync preferences and then sync the apps to the iPad. If you want to use WiFi syncing, select that option in the summary tab and click on Apply in the lower right corner of iTunes.
Assuming that you are running the new set iTunes version, this will help with setting up syncing on the new Dell.
