just installed my Honor 3 router after second attempt! Followed this post
Unplug the Honor and switch it off. Put the VM hub into modem mode and wait for the base light to turn magenta (might look red)Once it’s in modem mode, the VM hub must then be powered off. Then, set up your Honor with the WAN port set to be in DHCP mode(probably will be already). Make sure it’s fully initialised (leave 5 min) and then put in the WAN cable to the VM hub (port 1 for me)and now power up the VM hub and leave to initialise you should then get a connection. This order only needs to be done the first time you connect your own router to the VM hub.
Not sure about the Honor sorting out its own setting as before following the above I had already been into its settings and changed to DHCP before rebooting everything and starting again when I couldn’t get it going. You may have to try the above more than once. All seems good so far and even if wifi bars drop on my phone connection is still good and slightly better speed than the hub.
Oh and if like me you get stuck and need the Hub back in wifi mode then you unplug Ethernet cables then stick a pin in the reset button on the back of the hub for a full 60 seconds, will reset out of modem mode and back to wifi.
I’m not tech wizard but it worked for me.
