Swap cables between the 857 and Modem and see and try that WAN port Speed setting.
If you connect a wired PC that has Gb Network card directly to the 6120, what light do you get there? Should be blue however if not, could be 6120. Might need help there as well.
I would also call Motorola and see if they can help as well. I called them last year to get a new power supply and got one free of charge. Seem like good support.
Keep us posted.
Did a cable swap between the 857 and 6120 and no-go.
Called Moto last night and they said "sorry" act of God. I kinda figured that. So, I'm back to the 6120 which is fine, I don't notice any difference in speed.
With the 857 I just changed the WAN setting from Auto to 1000MBPS and rebooted both the 857 and the 6120. The LINK light on the 6120 does not light up at all and the Globe on the 857 doesn't either.
I switched the setting to 100MBPS on the 857 and the LINK light on the 6120 flashes amber and the Globe light on the 857 comes up blue. I tested that e4200 (gigabit ports) I have with the 6120 and the LINK light flashes blue, indicating it's maximizing it's potential.
So, yes, I think my 857 was damaged. It looks like the surge came through the cable line, hosed my modem and then entered the 857 through the WAN port and hosed the gigabit part of it and possibly the wifi. I'm also getting spotty wifi connects/disconnects which didn't happen before the storm.
