What's New in BufferSpeed
1.2.1
October 12, 2026
See where your connection slows down, hop by hop. Path check: two minutes of timing to every router between you and the internet, from your phone. Run it on Wi-Fi, then on cellular, and BufferSpeed tells you whether the problem is your home network, your provider, or somewhere past both. Walk test: carry your phone from room to room while it times your router. Each spot is compared with the last, so "move closer to the router" becomes a measured before and after. Smart Care now asks the right questions after a scan and suggests one concrete check at a time, then measures whether it helped. Guardian and Agency: see your desktop's path runs and incidents on your phone, ask it to check now or trace a path, and get a notification when it finds something.
