Nätverksförmåge-testare för webbläsare
This reads the Network Information API: whether the browser is online, the connection type (wifi, cellular), and the browser's estimated downlink speed and RTT (round-trip time). Estimates are coarse and browser-dependent, so use them to adapt the UI, not to measure a link.
