How do I update the firmware using the network on the M2022W wireless model?

Open a web browser, enter the printer's IP address, and log in using the Admin Mode credentials (ID: admin, Password: sec00000). Select the Maintenance menu, click 'upgrade wizard,' select the firmware file using the browser button, and press next. SyncThru will verify and compare the firmware version, then the machine will begin upgrading and return to the home page when complete. (Pages 66-67)
