Zero or incorrect speed readings

Fix NetSpeedDisplay showing 0 speed or numbers that do not match what you expect.

Safe checks first

1. Is anything transferring? Start a download and see if the value changes.
2. Right adapter? Select the adapter you are actually using. See network adapters.
3. VPN active? Traffic may appear on a virtual adapter. Try the VPN adapter.
4. Units: KB/s, MB/s and Mbps differ by a factor of eight. See units explained.
5. Restart NetSpeedDisplay.

If it still reads zero, email support with your Windows version, edition, and adapter type.
