my internet is out at my home, and I'm curious if the sign in for the wifi will affect the portions of the downgrade or A9LH instillation where the 3DS itself has to connect to the Internet.
Not really, I've been in that situation. I use a laptop to spoof the MAC address of the DS so I can sign in to their wifi from the DSes mac address, than disconnect the laptop, and connect the DS, and all is well.If you have to visit a webpage to connect then it won't work on the 3DS.
You should write a tutorial aimed at dummies and post it on the tutorial section. I didn't really follow what you said but would like to be able to do this.Not really, I've been in that situation.

Like mobile phones have IMEI as the unique identification number worldwide, wifi only devices have a MAC address (a smartphone connecting to the Wifi will have a Mac address as well).You should write a tutorial aimed at dummies and post it on the tutorial section.
