At first it was thought the problem involved the positioning of the antenna on the back of the device. But in a recent knowledge base article, Apple has come forward with an explanation and is assuring customers that this has nothing to do with the iPad hardware itself. Instead, the company claims it is third-party dual-band routers that are causing the issue and suggests a fairly simple workaround: creating separate names for different Wi-Fi bands (add a G to the 802.11b/g network name and an N to the 802.11n, for example) and make sure they have the same security settings.
If that doesn't work the article suggests resetting the iPad's network settings under the following file path: Settings > General > Reset > Reset Network Settings. Users are also advised to make sure they are running up-to-date wireless router software and that they are within range.
