Post update Moblab Ethernet connectivity should work

Post Guado (both Auto & Manual) update to latest v8872.67.0, Ethernet connectivity not working on ChromeBox, Now its stopped working on both the setup.

This happened after the moblab was upgraded to the newest version

Need Google’s input on this issue.

With older version of Guado image (We got issue as “Either chrome ran out of memory or the process for the webpage was terminated for some other reason”. So we updated the Moblab.

But, Post Guado (both Auto & Manual) update to latest v8872.67.0, Ethernet connectivity not working on ChromeBox, Now its stopped working on both the setup.
It's not the network because other computers/Panther Moblab are on the same network, wired, and working fine. I've tested multiple cables & ports on the same router and still the ChromeBox cannot connect.
It worked yesterday on 1 setup for ~ 10 min where Web GUI is not fully loaded, later disconnected. 
Tried Hard Reset & Power wash it still refuses to connect, even to wired Ethernet (Lab/another known working Ethernet cable) and Wi-Fi  option is turned off (Wi-Fi Enabling option is disabled at this stage). 

Without Ethernet connectivity on initial welcome screen of ChromeBox won't be able to log in further to change the settings (to turn on Wi-Fi & other). Need Google’s input on this issue.

While Reverting back to older image also, it checks for connectivity where it still refuses to connect on “Chrome Welcome Screen”.
