Error code in ACNL

[CupcakeZombie]

(If there's already a thread that's similar to this, I apologize)
I have gotten the error code 018-0512 a few times, and it's really frustrating! I have missed many chances of getting villagers or items, or just to visit someone for fun. I just wanted to see if there's more people who keeps getting this code and have a solution for it? (that isnt about assigning a new IP address or turning of the firewall, or something like that, because I cant do that.) Also I have never gotten error codes on Pokemon (for example) it just happens on ACNL.
I would appreciate help, because this stupid error code is destroying all the fun of ACNL online for me.

Place the Nintendo 3DS into your router's DMZ (demilitarized zone)*.

Placing the Nintendo 3DS in your router's DMZ will allow it to bypass your router's firewall and may allow you to connect with others. [How to]

Yeah I know this error code and I agree it can be really frustrating -.-'
I usually get this error code when the weather's bad or I haven't switched off my Nintendo 3 DS/wirwless of my Nintendo 3 DS/router for a few days.
Do you restart your wifi or 3DS if you get this error code?
It might help also visiting or inviting works after a few times asking porter without restarting anything...
