Connect on fake DNS

Mon May 29, 2023 5:31 pm

Hello All, i am trying to set a dhcp to enable phones to connect to a wifi with no internet in order to connect in intranet.
The problem is that the phones constantly disconnect finding another wifi bec they see no internet here.
Since is a lot of phones and cannot configure all of them, is there a way to make them think there is internet here, so they dont keep disconnecting?
Any ideas appreciated.
Thanks

It all depends on how the phones are checking for Internet connectivity.

If the phone is trying to connect to a specific Internet website or IP address to determine if it's conencted to the Internet then, no, there is no easy way to resolve the problem.

The other thing that might be happening depends on your setup. Do the DHCP clients (the phones) get given a gateway IP address (even if it isn't a real gateway)? Some systems, if they don't have a gateway IP defined, assume that the network is down and will disconnect. The simple solution in that case is to put in a gateway IP that can't route traffic (or blocks all traffic going to the Internet).
