Lenovo PC Diagnostics vs Internet Quality

When your ThinkStation workstation (models P920, P720, P520, P520c or other supported models) or ThinkPad P series laptop encounters a diagnostic error, this app decodes it from audio signals, even if the the system will not boot or fully power on. You can also use the app to check your warranty status, look up diagnostic codes and manage all of your system diagnostic events in one app.

Internet Quality shows how your Wi-Fi actually performs, room by room and right now. Walk through your home with your iPhone camera. Internet Quality measures your connection at every spot you pass and builds a map of where your Wi-Fi answers fast and where it struggles, live in AR, then as a 2D floor plan and a 3D map you can revisit and share. WHY NOT SIGNAL STRENGTH (dBm)? iOS doesn't let App Store apps read Wi-Fi signal strength in dBm, so an iPhone app that shows it is estimating. Internet Quality measures what signal strength only hints at: how quickly and how reliably your router answers you at each spot. Strong bars don't guarantee good Wi-Fi. Interference, crowded channels, thick walls, mesh hops and a busy router all slow you down while the signal still looks full. Response time and dropped replies show what your video calls, games and streams will actually get. WIFI OR INTERNET?
