So today I bought a new3ds xl 10.7 32, as far as I know I can downgrade and install a9lh which I think is the best cfw for the 3ds, with 10.7 I know that I don't need a hard mod, nor any games for that matter because browserhax should work, but my problem is that I have no access to the router, I looked up browserhax instructions that says I have to access the router to block the Nintendo website, but I also heard from another member here that it is optional, it's just a precautionary measure to prevent update or something, so I wonder if I can safely use browserhax without accessing the router to block nintendo site? I also heard that I can use DNS, but I have no idea how that works. Thanks
