I have a Cisco Airnonet 1230B on the top of my building with a 9 DBI omni antenna, totaly isolated from the exterior, powerd with POE (about 50 meters long), and untill now everything went perfect, but yesterday the AP sudently went with no signal/ very poor , first i thought that it was from the pigtail or the connectors, but it was all ok, then i thought that was something wrong with AP, ive tooked to my house and tested with a 2 dbi antenna , when i was mesuring the signal with one wireless client ive noticed that in 1 meter of distance i was associated with -80/45% signal, and the power in the configs was on MAX , radio enabled, antena on the RIGHT, ap configuerd on the right antenna, and antenna gain DISABLED. Could this means that the mini-pci inside the AP could had a shoruted circuit and burned out the main amp. of the ap ?
Yes ive tryed on both left and right terminals and the siganl was the same.
The outside conditions ( weather ) yes it has rained a lot, and we had a strong thunderstorm just the night before ive noticed the problem ( maybee thats the cause of the problem, ive noticed that the lighning protector was missing, some wise guy took it of... ), the power grid in this area it had been 100% fine , also i have an UPS were the power supply of the AP is connected. All the coax system is 100% ok no changes.
