Set up Calibre’s content server (if you prefer wireless transfer). In Calibre, go to “Connect/share” and select “Start content server”. On your Kindle, open the web browser and enter your computer’s IP address followed by “:8080” (e.g., 192.168.1.2:8080). Browse and download the eBooks from the Calibre content server. 7. Use Alternative Reading Apps (Optional) For a more versatile reading experience, you can install alternative reading apps on your Kindle, but this might require jailbreaking your device, which can void the warranty and risk bricking the device.
