look, i finally set up wireguard on my router cuz i was bored and i'm genuinely surprised it didn't melt. the pro is obvious: every single dumb device in my house, including the smart fridge that probably snitches on my cheese consumption, gets encrypted. the con is that my kids now think netflix is a buffering simulator and i'm a household villain. spent a week comparing throughput against the app on a desktop. router vpn is like putting a civic engine in a semi-truck - functional but you're not winning any races. apps give you protocol switching and split tunneling on the fly, which is great when you want to torrent while pretending to work. router method? you get one setting for everyone. my data shows a 40% speed hit on the router versus 15% on a wired app connection. but hey, at least the thermostat's data is private now, lmao
