I have been running a 2 nodes Deco mesh using the X60 with wired backhaul, it's been working great for a few years now. I am moving house and it doesn't have Ethernet port, it doesn't look possible...

I agree I have also asked TP-Link what differences between v1 and v2 and got the same basic answer that there isn't any. So why is there 2 different versions? TP-Link really needs to be more...
