    Hi @Don,

    Welcome to Zyxel community!

    We had this similar issue on our switch after the Firefox browser upgraded to version 49.0.1 and the issue has already fixed by the latest firmware version.

    Please make sure your switch's firmware version is the latest version V2.30.

    Hope it helps.

    I'm having the same issue, with a GS1900-48. All my browsers are up to date (safari, chrome, firefox), and I can't upgrade the firmware because it says

    "Image Signature Error. Please make sure the image is correct"

    Based on your description, "Image Signature Error. Please make sure the image is correct" means that the firmware file is not correct.

    Please verify if your v2.40(AAHN.1) firmware file size is 6,810KB (zipped).
    Or kindly refer to this link and download the latest firmware version v2.40(AAHN.1).
    Then try to upload again to solve the issue.

    Hope it helps.
