So Lazada didn't quite have a big 10-10 sale or anything, but I went ahead and got some Google Wifi units for the Sietch. Setting up the base pod was pretty easy but the second one gave me some trouble, but a factory reset cleared those issues soon enough. And now we have a mesh wifi network probably oversaturating our one-bedroom condo, but who cares, right? It's another Google thing in our home!
Long story short: the WiFi signal in the bathroom is a LOT better now.
