We have 2 branches that have each an RAP-93 and they are complaining about WiFi signal and dropping connections.
Here is the output for one of them (the other is almost the same):

Our SSID's are "OFFICE1" and "OFFICE1_A".
The solution that we thought are as follow :
1) Changing the Min TX EIRP to 18 (but doing this will make the cell of coverage smaller and we wouldn't have service in all the branch)
2) Adding a second RAP 93
4) Changing the to a RAP-105 and steer clients more to the 5GHz instead of the 2.4.
The RSSI is -61 at the far ends of the coverage. (values were obtained while using a smart phone).
