Switching Hub 3.0 to Modem Mode and Back Again

[ChrisJB1]

I am about to switch my Hub 3.0 from router to modem mode so I can attach my own router which has better security options for segregating my IOT devices from my main network containing my PCs etc. My question is, were I to run into trouble with setting the new router up and wanted to revert to using the Hub as a router as before, would it still retain all the various settings for IP addresses etc that it currently holds or would I have to start again from scratch and re-enter all  the settings?

Not sure as it's not anything I done, I'm always in modem mode.  You can however, backup your settings when in Router mode and restore when needed.

Set it up this way....

_______________

Switch on and set up your own router or first Mesh unit (in its settings) to have its WAN port set to be in.. Dynamic/Automatic IP or DHCP (& Nat) mode, it may be pre-set that way anyway. Then, disconnect all cables from your new router (or all Mesh units) and switch them off and unplug them. Then, put the VM Hub into modem mode ( https://www.virginmedia.com/help/virgin-media-hub-modem-mode ) and wait for the base light to turn magenta/purple (on a Hub3 - but green on a Hub4 or Hub5).

Once it’s in modem mode, the VM hub “MUST” then be powered off. Switch your router on and make sure it’s fully initialised (leave 5 min) and then put in the Cat6a ethernet cable from its WAN port to the VM hub (any port will do).

NOW… power up the VM hub and wait 5-10 minutes for The Hub to initialise and and you should get a connection. Use the recommended App to connect any other Mesh units to the first one. This order only needs to be done the first time you connect the router to the VM hub. You might also set the SSID and key/password on the new router/Mesh to match that on the HUB so when you swap over, all your wireless devices should just connect automatically.

Yes you can switch back when in modem mode by 192.168.100.1 but you be getting the service you are meant to get from VM in modem mode
