Hub 3 cannot change DHCP Address to 192.168.1.0
Trying to change the DHCP starting address on the HUB 3. IT is currently 192.168.0.10, when i set it to 192.168.1.10 it fails with "ip address is invalid" error. Changing to 192.168.2.0 works fine. ...
Except, the OP claims that changing the subnet to 192.168.2.0 (presumably /24) works OK. Which suggests that, at least on the Hub 3 it is still possible to change the LAN IP subnet.
The reason they can’t use the 192.168.1.0/24 range is because it is reserved for the guest WiFi network and this is still the case even if you aren’t using the guest WiFi. Alas there is no way round it, short of the modem mode, own router option.
