Oh man, I feel your pain on this one! I did the exact same thing last year and that paperclip reset hurt my soul, because I had named every device on my network and set up guest access and all of it just vanished in seconds. Now I snap a photo of every settings page on my phone before I touch anything, and I keep a little notebook with the login info and the weird options written down too. My family thinks I'm nuts but guess who never lost two hours to a router again. Better paranoid than locked out, that's what I say.

Make your own, honestly, saves so much money.

Does the grocery bag trick work when the cavity has fire blocking partway down, or does it just snag on the wood? Seems like the suction would die once it hits a horizontal block. Curious how you get past those spots without cutting in.
