firmware size?

[DAIDAI]

Hi,

I' concerned about NW traffic because firmware upgrade, I have many MRs.

Someone knows firmware size(kB or MB) of MX, MS, and MR?

I don't, but I suppose it might be possible to discover by forcing an update and capturing with Wireshark. Do you also have MX?   It would simplify packet capture.

I suppose you have capped/expensive internet service?
