When the Sierra Overdrive 3G/4G hotspot first became available from Sprint, many users (including our testers) experienced a number of frustrating problems. Luckily, Sprint and Sierra Wireless released a firmware update (Version 2.06.06) that vastly improved stability, increased WiFi stability, increased 3G/4G WAN stability and even improved the battery life! Making sure that your Overdrive is up-to-date with the latest firmware ensures that you've got the latest functionality as well as increased stability.

The process for upgrading the firmware is pretty straightforward - you can run an automatic upgrade or do it manually:
