Hello all,
I'm facing problem in AP. We are using standalone access points, all's working fine but signal strength is very weak.
Product/Model Number:
|
AIR-SAP1602E-E-K9 |
System Software Version: | 15.2(2)JB2 |
What I need to do solve this problem.
Solved! Go to Solution.

You have no antenna attached at all? The E models are designed to be used with some form of antgenna, but with nothing attached any signal will be radiated just from the internal connections... Even the little "stick" antennas will give considerable improvement.
The ADVANTAGE of the E is that you have the capability of "optimizing" the antenna based on your needs. Simple omnidirectional, to Yagi directional antenna - whatever suits the environment. But you DO need some antenna or you will get minimal signal. "I" models have an internal omni built into the case - non-optimal, but simple and normally adequate for many environments.

If the AP is set to the highest TX power, there is really nothing you can do to cover more area. When you say the signal is very weak, are you pretty far away from the AP or are there wall or obstruction between you and the AP?

Yes, transmit power is maximum. When I 10 steps away from AP it's showing connected but not signal.

hi,
try doing a site survey and look for possible interferences (neighbor AP/wifi, microwave oven, cordless phone, etc).
you can tweak the 2.4 GHz radio interface: Network > Network Interface > Radio0-802.11n 2G.Hz
Data Rates: Best Range
Transmitter and Client Power: max
DefaultRadio Channel: Least Congested Frequency
you can also enable and configure the less crowded 5 GHz radio: Network > Network Interface > Radio0-802.11n 5G.Hz > Enable Radio > Enable.

Hello,
Thanks for your reply. It's already set to maximum transmit power and best range but still issue is the same.

You need the proper antenna.

This is an E model - what antennas to you have connected to the AP?
03-06-2017 06:28 PM
Hello,
Yes this is E Model. We are using without antenna.
03-06-2017 06:31 PM
You need an antenna for any "E" model antenna. This is what the others were leaning towards.

Ok thanks for your advice.
What type of Antenna we need. This is office where we using APs approximately all users in room.

You can just go with a dipole or maybe any ceiling mount Omni.

maybe this antenna: AIR-ANT2535SDW-R – Dual band (short) dipole (4 required) – 3/5 dBi Dipole

Ok thank you. I'll check with antenna and update you.
03-06-2017 07:05 PM
Here is another one if you want to place the antenna above the ceiling and this on the ceiling tile:
AIR-ANT2524V4C-R=
You want a dual band 4 element Omni antenna

Thank you.
Do I've to configure AP for Antenna. Or Antenna is just plug and play.
03-06-2017 09:23 PM
Basically plug and play. You can do some funky changes, but that's if you want to disable antenna ports which you don't want to. Just get the proper antenna that meets your needs and you should be good to go.
