Modem mode vs simply switching off WiFi

Just got a new Hub 5 but I’m going to be using my own mesh system, reading up putting it into modem mode seems hit and miss, what’s the difference between that and simply switching of WiFi on the Hub 5? That way you can also use the Ethernet ports on it.  

This is probably a really stupid question 🙂

    Main reasons other than those just stated are that in router mode the VM hubs have very few options for tailoring parameters and the biggest one is that they work excellently as just a modem because the under powered CPU does not have to do DHCP, WiFi and network switching. If you have not got many ports available, just buy a cheap network switch for about £15.

    An equally possible approach is to use the Hub in Router mode with it's Wi-Fi enabled
    and configure your Mesh in Access Point mode.   Think of the Hub as a free Wi-Fi AP with 4 ports !

    One day VM will do CGNAT to the point in router mode they don't show your WAN IP and show nothing but you going to whats my IP site and is that really your IP?

    Support modem mode let VM know you want your own WAN IP

    Try setting it up again as per....

    _________________________


    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.
