STA Receives Strong Signals from an AP, But the Network Speed Is Slow. How Can I Locate the Problem?
Locate the problem as follows:
- Check the number of users associated with the AP. The number of associated users cannot exceed the upper limit allowed by the AP.
- Check the channel and power of the AP. The channel and power must be set to fixed values, but cannot use default settings.
- Change the connection mode on the AP to high-speed access.
- Check whether upstream bandwidth limit is set on the AP.
- Check antennas on APs:
- The interval between the antennas on different APs cannot be smaller than 10 m.
- The interval between the antennas on the same AP cannot be smaller than 7 m.
- Use the dedicated tools to scan adjacent-channel interference. Check whether there is strong interference near the STA.
