I purchased an iPad from Apple, and I have been having a problem getting a connection to my wifi home service only. When I begin using the iPad from sleep mode there is no wifi connection. It takes about a good 5 minutes for the wifi service to begin working with the iPad. The iPad has no problems when it is used with another wifi service such as with my employer. Also I have other computer equipment in my home where it picks up wifi service with no problem. Please advise. Thanks.
