MS60 Amber Lights on All 3 Satellites, Blue Light on MR60. Satellites Have Internet.

I was having pretty much the same issues! Same diagnosis from yesterday evening. Thanks to your Post I got to the solution (with some extras) . The only step missing for you is to upgrade your MR60 firmware to 1.1.6.122. The MS60s are already ok.

So to sum up for the community:
- Upgrade triggered late afternoon yesterday.
- after this, Router kept blue led, 1 satellite was blinking white, 2 were steady amber.
- overnight after a couple resets, nothing happened and the connectivity was terrible!
- This morning after 2 straight hours (luckily within my stay at home holiday) I managed to confirm that: Router had not been well updated (and no upgrade was proposed by the system %#*#), the 2 amber led satellites were good with the 1.1.6.122 version loaded and running, and the white blinking m*** was not reachable (nothing, neither resets, nor direct 1 to 1 ethernet with laptop was effective).

This was it, the full diagnosis. Two upgrades, one to go and one damaged device. Now to the action.

- 2 Satellites were OK so no action.
- Router, upgrade thanks to downloadable package
- Damaged satellite (tricky one): access with direct 1 to 1 ethernet and TFTP file upload.
