Problems solved by technology

Thus, it is impossible to constitute optimal communication conditions for communicating with the access point
Furthermore, it does not take into account interference from other wireless devices or the MFP's surrounding environment (for example, the material of the wall where the MFP is installed, the distance from the wall, or other factors that may cause radio wave interference with opposing devices) Countermeasures
[0006] Besides, in the case of MFP, there is such a problem that, for example, even if the communication conditions are suitable when the MFP is installed, it is still difficult to know how the communication environment due to external factors will subsequently deteriorate

Embodiment Construction

[0018] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] figure 1 The external structure of a digital multifunction peripheral (MFP) of an image forming apparatus according to the present invention is shown. Specifically, the MFP 1 includes a sheet conveyance cassette 2 at its front lower portion, and an operator panel 3 at its front upper portion. An automatic document feeder (RADF) 4 is assembled on the upper part of the MFP1. In addition, a main antenna 5 and a sub-antenna (sub-antenna) 6 are provided on the rear side of the MFP 1 . The main antenna 5 and the sub-antenna 6 are constituted by, for example, a dual-band antenna. Furthermore, the operator panel 3 is provided with a liquid crystal display unit 7 .

[0020] figure 2 The structure of MFP1 is schematically shown. The MFP 1 includes a main CPU 10 that performs overall control and can be used as an acquisition device; ROM 11; RAM 12; a ...

Abstract

In a digital multi-function peripheral, a network button (Available Network) is provided on a liquid crystal display section of an operator panel. When a user presses a currently available network button, a wireless communication control unit provides a main CPU 10 with an SSID that is used in a connectable wireless device (access point), along with a wireless mode, a channel and an RSSI. The main CPU causes the liquid crystal display section of the operator panel to display the RSSI value that is provided from the wireless communication control unit.

Description

technical field [0001] The present invention relates to an image forming apparatus having a wireless LAN function such as a digital multifunction peripheral (MFP), and a wireless communication control method. Background technique [0002] In recent years, with the development of wireless LANs, there has been a problem that adjacent wireless LAN systems interfere with each other. Therefore, it is very important to provide countermeasures against this problem, for example, to recognize communication conditions (sensitivity) on the device side of a digital multifunction peripheral (MFP). [0003] However, an image forming apparatus such as an MFP does not have a countermeasure against an indication of communication sensitivity such as a wireless LAN. In other words, the image forming apparatus does not have means for providing optimal installation conditions for communicating with opposing wireless devices (ie, external devices such as access points). [0004] Also, currently...
