Hi @Franz_Stegmaier,

Welcome to Zyxel Community!

Regarding the firmware upgrade issue with your GS1900-24E switch, here are several troubleshooting steps to resolve this problem:

1. Firmware File Format Verification

Please ensure you are using the correct file format for the upgrade:

• After downloading the firmware file, unzip the archive completely
• Use the .bix extension file (not the .zip file) for the actual upgrade
• The correct firmware version for GS1900-24E is: V2.90(AAHK.1)C0

2. Firewall Configuration Check

Firmware upgrade failures are commonly caused by firewall restrictions:

• Temporarily disable your operating system firewall during the upgrade process
• Ensure TFTP/HTTP/HTTPS services are not blocked by your security software
• Check that your antivirus software isn't interfering with the upload process

3. Firmware Upgrade Method

Web UI Upgrade

1. Access your GS1900-24E via Web UI → Maintenance → Firmware
2. Choose the "Upload" tab and use the "HTTP" method
3. In Image section, choose: "Backup" (for safer upgrade)
4. Click "Browse" and select the .bix firmware file
5. Upload the file and wait for completion
6. After upload completion, click on the “Management” tab
7. Select the backup image you just uploaded, and then click “Apply” to set the backup image as the boot image
8. Navigate to Maintenance → Reboot to manually restart the device
9. After reboot, verify the firmware upgrade is completed
