If you've good signal strength in all your Signal Strength indicators, but your airFiber5 link isn't able to modulate at maximum data rate for these signal levels (please check the AF5/5U Receive Sensitivity table for more information), please make sure your link meets the following parameters:
- Clear Line of Sight (LOS) between two sites
- No objects that could be causing reflection issues. If the antennas are installed in a roof with metal or any reflective surfaces, install the AF5 as high up as possible, at least 3meters (10ft) above any reflective surface (please read this article Best location for a high performance link)
- There's no high interference in the frequencies you are using, you can use airView to determine the best channel (available in firmware 2.1 or higher)
- There's no signal mismatch among 4 signal strength indicators. Maximum deviation should be less than 4dB.
Important: Since firmware version 2.2, signal strength bar is automatically adjusted to link distance, so if link is aligned perfectly it will show full signal strength bar.
