WLAN Latency on Cisco 3650 and LAP2702

[Nicolas Rennetaud]

Hi,

I'm encountering some issues with my network installed last month. There are one Cisco 3650 MC and two LAP 2702. 

Users have latency problems using this network. Laptop to laptop, there could be 400ms ping answer on the same SSID.

Do you know if there's any configuration to implement on the switch of if it's already configured for best performances ? For information, we've tried to connect on g/n on 2.4GHz and n/a on 5GHz and it's always the same.

Thanks in advance.

Regards

Nicolas

Hi Nicolas,

Do change the below setting in WLC:

1. Click on Wireless>>>802.11a/n/ac and 802.11b/g/n>>>RRM>>>>TPC>>>TX power level assignment >>>fix it 1.

2. click on wireless>>>>802.11a/n/ac and 802.11b/g/n>>> network >>>>Data Rates

1 , 2, 5.5, 6 Mbps === set disabled all.

6 Mbps  === disabled

9 Mbps ==== Mandatory

Hi Kamlesh,

Open a new thread as your issue is not related to this original thread.

Also attach AP console output while it is trying to register.
