I’ve bought a Netgear Orbi mesh system, would I be better putting my Virgin hub 3 in modem mode or leaving it as it is ??
that's teh general recommendation, yes. The orbi routing features are likely to be a lot richer than the hubs.. you need to follow a specific sequence to get modem mode set up..
Log into the hub on http://192.168.0.1 and select the option to put the hub into modem mode The hub will then reboot and come back up in modem mode - give it five minutes to settle down Disconnect all ethernet cables from the hub Power off the Hub and your router/mesh system Connect your router/mesh system to the hub via ethernet cable and switch it on - leave it five minutes to settle down Power on the hub and leave it five minutes to settle down
