Hi. Should I leave the wifi key as the default one ? I've always changed the default or just rename my network? Thanks
Entirely up to you. The default is unique and strong so no real reason to change it unless you have a vast number of devices to change the password on.
Thanks about the key any need to change the network name for a bit of extra security?
The network name is just that.. a name. No matter what it is it can still be found even if you hide it so there is no security reason to change it.
