Hi,

I’m considering purchasing the TP-Link M8550 and noticed there are different hardware versions (v1 and v1.6).

Could you please clarify:
1. Are there any differences in performance or stability between v1 and v1.6?
2. Do they use different chipsets or internal components?
3. Is firmware support the same for both versions?
4. For long-term 24/7 usage with a mobile SIM, which hardware version is recommended?

Thank you for your support.
