Hello, we are a small ISP and we have installed the Chateau LTE6 for new customers, and we are dissapointed with its modem reliability (FG621-EA).

Without external antennas has bad reception, but its major issue is very bad reliability: we need to reboot it almost each day to keep it connected to LTE. It disconnects for whatever reason and never reconnects, or it shows "connect failed" in red and we need to disable the interface and reenable it, or reboot.

We have even seen, not once, not twice, that the lte1 interface disappears until a reboot! We updated its firmware to latest version (16121.1034.00.01.01.04) with same results. Updating RouterOS and its firmware doesn't help either. It's frustrating.

What's your experience with this modem?

Well, then you should contact support@mikrotik.com additionally. It's OK to ask community here for experiences, but to really resolve the issue its better to contact MT or the distributor where you buy your devices from.

You are right, but we would like to hear other experiences before if possible. Thanks for your reply!
