i try to install D-Link access point with 4 dBi, actually the D-link access point wireless coverage range better than CISCO AIR-CAP1702I-E-K9
Hard to determine why the signal for the 1700 is bad as there are a lot of factors involved.
1. How is the AP installed;
2. Co-channel interferrence;
3. Distance of the AP being measured;
4. Data rates used;
5. Dynamic power assignment
