# ACKSYS WaveOS - Firmware upgrades for Cellular cards

Changes Log Known issues

## Release notes

### Upgrade instructions

Firmware upgrades for EC25 and EG25 cards come in "delta" form, meaning that only the part which is different between the current version and the next version will be upgraded.

The upgrade package is a "ZIP" file containing other ZIP files named after the firmware versions. So, you must select the precise firmware file which matches the firmware currently installed in the product, and the firmware you wish to install.

You can use the browser interface to find out the version currently installed.

- First, enable the cellular interface in SETUP/Physical interfaces/Cellular
- Second, go to TOOLS/Firmware upgrade/Cellular upgrade; the current version displays just above the file selection field.
- In the file selection field, choose the appropriate ZIP upgrade file for your case, such as "EC25EFARCurrentVersionM4G-E25EFARNewVersionM4G-update-date.zip"
