The SBG3600 LTE performance seems to be much lower for me than it should be. Are there any firmware updates? This is what I've got now:

Main Current Firmware Version: V1.00(AAKO.9)

WWAN Current WWAN Package Version: 1.15

LTE Current Firmware Version: ALT3100_04_05_06_10_B8_LO

kind regards,

    I have Zyxel SBG3600-N B model, please send me a link to latest firmware also for the router and the LTE upgrade. My current firmware is V1.00(AAZE.2) I downloaded several version from the Zyxel website, but It was not clear which was the latest version to use, and received error messages during upgrade on one of them.
