MR60 wont connect to 3 out of my 4 satellites after hard reset of router

[TB0000]

All 4 satellites were connected and solid blue leds prior to hard reset.

I reset the router because the system was dropping out quiet regulararly (noticed it primarily on my 10x shelley smart home relays that are connected to wifi).

Now router is a solid blue and 1 satellite is blue also however the other 3 are amber.

Have tried, power on / off etc, sync, new satellite setup in android app but nothing seems to work - lights are the same (amber) and app only should 1 connected satellite and does not discover the other 3)

What firmware is on the router and the satellites? 

You can hardwire a pc/laptop into the disconnected satellites. when hardwired in, their default address should be 192.168.1.250

You potentially can log into them to check their firmware version. 

Another thing you can try is hardwiring them in to update/sync them. Then disconnect and re-add them.
