If you are experiencing difficulties using the DR-C225W or DR-C225W II wireless (via Wi-Fi ) on macOS 11 (Big Sur), please follow the steps listed below.
Use the Wireless Connection Tool to automatically acquire the required network information from the wireless settings of the computer connected to the access point, and connect the DR-S150 to the same network. Follow the steps listed below to successfully connect your scanner to a wireless ( Wi-Fi ) network.
Connecting to a Specified Access Point To connect the scanner to a computer via an access point that does not support WPS, select the access point for wireless connection from a list. - If the access point is using security settings (such as MAC address filtering), change the settings to allow connection to this scanner. - To ensure good Wi-Fi communications, perform this procedure with the scanner initially located close to the access point.
