I think in all my network installs, the pre-setup only worked out 1 out of 10 times. So I no longer do that. Why not try it? You might get lucky.
I have a Ubiquit EdgeRouter PoE and AP that I am going to be installing in my new home within the next couple months. Can I set up the router and AP offsite and have it ready so when I move into the new house, I have little work to get it up and running? The reason is I don't have a TON of IT experience (just enough to make me dangerous) and want to test/experiment with it before moving in.
