Are you sure there's not a moisture problem in the antennae cabling?  Get
an SWR meter that can handle the 2.4 GHz range and make sure that SWR is
very low (approaching 1:1 but certainly less than 2:1).  Hook up the meter
in-line at the AP.  Test this after everything is wet and again when
there's been a dry spell.  Minimize the number of exposed connections and
use dielectric grease.

Use dielectric grease sparingly on the outer threads of the connector. Don't let it get in contact with the inside where it bridges the center pin and the shield. This will cause nasty impedance bumps. The inside of the connector should be dry. The grease on the threads helps to ensure this.

Any exposed connections should be well wrapped
with that rubberized electricians tape first, then with regular.

Yep, the stretchy stuff. 3M type 23.
