Hi,

1) How are you powering the access point ? PoE ? Power supply ? If power supply, how many volts does it indicate on it ?

2) Can you show your configuration (show run) ?

3) Did you plug the antenna on the correct side of the access point ? (it should mention 5ghz, antenna A)

3) Did you plug the antenna on the correct side of the access point ? (it should mention 5ghz, antenna A)

A: Yes I have plugged the 3 Antennas in 5GHZ antennas side

Boot the AP.  Post everything during bootup including the "sh log" and "sh version".

[mohammed-amjad]

Hi,

Please find the attachments of show log and show version and this access is converted from LAP to AP.

Thanks,

[Nicolas Darchis]

All looks ok (by the way, the fact that your ssid is WEP prevents to use 802.11n which is a shame with an AP allowing 802.11n :-) )

Can you say which client wireless adapter you have ? The exact model ?

Regards,

Nicolas

[mohammed-amjad]

Hi,

I am using Broadcom 802.11g Network Adapter

[Nicolas Darchis]

So your client is not capable of 5ghz :-)

The AP is transmitting fine on the 5ghz but it's the client who just cannot receive it.

[mohammed-amjad]

Hi,

Thanks for your reply and just I need to know which client adapter will work for this access point.

[Nicolas Darchis]

Any that is capable of 5ghz ? :-)

Usually they put a "a" in the name. Yours only does 802.11g (2.4ghz).

Intel writes "3945 ABG" or "ABGN" if it does 11n as well.

Hi,

Please find the attachments. I brought Linksys WUSB600N Wireless Adapter to support 5GHZ and it works fine but giving me an error when I go little far from the access point I am loosing the signal and I am getting week signal. (What if I use AIR-ANT5195P-R antenna and if I use AIR-5135D-R antenna)

I am getting these errors: Interface Dot11Radio1, Deauthenticating Station 0025.9c9a.fe37 Reason: Sending station has left the BSS

How to fix this problem?

[Nicolas Darchis]

What distance are we talking about ?

[mohammed-amjad]

Hi,

The distance is 2-3 meters far only.

Thanks,

I have this same access point, currently I can only configure it to with WPA - TKIP. How do I upgrade this to run WPA-2 AES encryption. I'm on site and would like to upgrade not just this one but all the others that I have as well. Please help. My current software version is 12.4(10b).JA3

[Stephen Rodriguez]

Lonny,

     This is a very old thread, you really should open a new one.

That being said, the 1252 supports WPA2/AES in that version of code

HTH,
Steve
