AP Range and signal strength is very weak

[Jawad Ahmad]

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:  Product/Model Number: AIR-SAP1602E-E-K9  Top Assembly Serial Number: FGL2035X04H  System Software Filename: ap1g2-k9w7-tar.152-2.JB2  System Software Version: 15.2(2)JB2  Bootloader Version: BOOTLDR: C1600 Boot Loader (AP1G2-BOOT-M) LoaderVersion 15.2(2)JAX, RELEASE SOFTWARE (fc1)

AIR-SAP1602E-E-K9

System Software Version:

15.2(2)JB2

What I need to do solve this problem.

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?

[Jawad Ahmad]

Hello,

Yes this is E Model. We are using without antenna.

[Scott Fella]

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.

[Scott Fella]

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.

[Scott Fella]

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. 

[Scott Fella]

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.
