Can you perform a "show wlan X" where X is the number of WLAN you're using? Is it configured for WPA2-AES with WMM allowed?

On the MAC recommend that you install: WIFI Signal

https://www.adriangranados.com/apps/wifisignal

Then post what SNR, RSSI and MCS you are getting.

As mentioned, can you share the config of the WLAN you are running.

Hi,

 54 Mbps based on what?  It is an speedtest or something similar?  Or this is actually your air interface speed? Keep in mind that channel width is on variable on the equation.

-If I helped you somehow, please, rate it as useful.-

[Haydn Andrews]

Has a site survey been conducted

From the CLI of the 2504 please share:

show wlan <ID>

debug client <mac address> - share the output of client connecting and disconnecting

Is the 54mbps the data rate being received? or the throughput of the client to speedtest.net?

what RF profiles do you have enabled. Is 802.11ac enabled?

What is the client device? is it an 802.11n or ac device?

[wavelogix]

please attached , not only 54mbps , its disconnects the clients specially iPhones , above I have attached the show wlan 1

[Sandeep Choudhary]

chekc if you enable 802.11n or 802.11 ac rates.

Regards

[wavelogix]

Hi

I have enabled both radio's please see attached

[Ric Beeching]

Can you post a 'show 802.11a' and 'show 802.11b' from the CLI?

Also change your data rate to 20 MHz for now, disable the 802.11b completely and we can work up from there.

Ric

[wavelogix]

Hi Ric

I have moved to 20Mhz and disabled the 802.11b

[Ric Beeching · Accepted solution]

Thanks for the files.

Going back to Flavio's excellent question - Where are you seeing the stat that your client is connecting at 54 Mbps? Does the end device display it?

I would also make 54 supported as mandatory is a bit aggressive:

config 802.11a disable network
y
config 802.11a rate supported 54
config 802.11a enable network

Ric

Ah, it's a cosmetic bug with the Macbook:

https://forums.macrumors.com/threads/imac-pro-wifi-issue.2099199/

Assuming your Internet speed is more than 54Mbit/s, what speed do you get on that same Macbook if you do a speedtest? www.speedtest.net

Thanks,
Ric

[wavelogix]

hi Ric, i have made the cadges as per your suggestion and download the app as per Hayden , the result is much better , but see I have replaced one AP with 2702E as well. will monitor and update
