For anybody who switched off their wi-fi in fear of getting the update prompt for 9.3.0, if you have admin control of your wifi router just block nintendo's update servers according to the "Balanced Urls" in this thread: https://gbatemp.net/threads/blocking-update-servers-clarification-needed.367645/ (Note: This will block the EShop too!) Edit: Some users have reported their routers not blocking correctly, please be sure to test if your block works! You can see under the "Domain Name" I put all of Nintendo's update servers and set it so all incoming or outgoing connections to those domains are dropped all day every day for just my 3DS and JAP N3DS LL. I have it set so both my 3DS' will always get assigned the IP 192.168.0.220 and 192.168.0.221 and those IP's are set to block the domain names listed. So far both my 3DS and JAP N3DS LL have been connected to the wifi both on and in sleep mode for about 2 hours now and I've got no updates and I can still enjoy internet features like Nintendo Video/YouTube and such EDIT: If your router isn't blocking the domains correctly or your router doesn't support domain blocking try this: Warning: Spoilers inside! DD-WRT users: Domain blocking won't work since it only blocks HTTP and not HTTPS. If you don't want to use OpenDNS you can try something like this Warning: Spoilers inside! Note: I am not responsible for firmware update nags if your blocking somehow stops working. It's never happened to me before but you never know. Block them before they block you!
