 Wi-Fi access points are spaced at proper intervals so that Wi-Fi covers all School of Science buildings.  Wi-Fi access is available, even if no access point has been installed in the room.  If the radio field intensity is extremely low due to access point locations (and if there is a user need for Wi-Fi access), a slight adjustment of access point locations may be considered.  However, the addition of access points is difficult; since the narrow bandwidth of the 2.4 GHz band is shared, an excessively increased number of access points may result in radio interference, further degrading Wi-Fi performance.

 === Login fails for certificate-authenticated services (e.g. Meeting Documents) ===
 If you reissue a certificate for your School of Science account, the old certificate will be invalidated (this is a mechanism to prevent authentication with a certificate that was accidentally leaked). To make sure you have the latest certificate installed, delete the old certificate once and install the newly downloaded certificate and try again.
