Recently got 2degrees fibre at home and they supplied a Fritzbox.
 want to configure Fritzbox to be same setup as the Netgear router
Current netgear N series router has a TPlink switch attached
TP Link switch has 4 cameras attached
Home security cameras have static IPs

i.e 192.168.0.200, 192.168.0.201 the 202 and 203

Synology NAS static on 192.168.0.19

Now the default ip for Fritz when you plug it in is 192.168.178.1 - This works and can access the config pages

BUT when I try and change the Fritz ip address to 192.168.0.1 which should be same as what the old netgear was, it all seems to work in config.
After changing the ip to 192.168.0.1 the switch shows up as 192.168.178.24 and i cant access this address to alter the switch ip.
I also cant go to 192.168.0.1 and get the fritz router page even though this is showing as its new ip, i have to use fritz.box to access it again.

Because the switch is getting a higher ip and the cameras are static ip 192.168.0.200 to 203 these are all disconnected as well.
