Abstract: An improved apparatus and method are provided for wireless communication with computers. The communication apparatus is integral with a removable by cover of a computer case and operatively connected to memory means associated with the case. By mounting or affixing the wireless communication device to a bay or slot cover in the computer case, conventional existing computers can be readily retrofitted to include integral and upgradable wireless communication. In certain embodiments, a jack or other connection is provided in the bay or slot cover, and a removable wireless communication member is selectively connected to the jack. Cable means preferably connect a motherboard within the computer housing to the wireless communication device. The wireless communication device or connection may be combined on a single bay cover with a conventional device such as a diskette drive, tape drive, or the like.
