Poor wireless performance

Graham Bell — Mon, 05 Jul 2021 08:44:50 GMT

Hi Guys,

Been tasked with investigating poor performance on one of our APs at a remote site. Reports are of clients 'dropping off the network'. Initial diagnostics shows ping times as below (local layer 3 switch svi to wireless device):

monl3s01#ping 10.140.201.112 repeat 50

Type escape sequence to abort.
Sending 50, 100-byte ICMP Echos to 10.140.201.112, timeout is 2 seconds:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!.!!!
Success rate is 98 percent (49/50), round-trip min/avg/max = 8/136/1737 ms

But 5 minutes later, I get this:

monl3s01#ping 10.140.201.112 repeat 50

Type escape sequence to abort.
Sending 50, 100-byte ICMP Echos to 10.140.201.112, timeout is 2 seconds:
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Success rate is 100 percent (50/50), round-trip min/avg/max = 1/4/17 ms
monl3s01#

Yesterday when the problem was reported I got the following results from wireless device to local router:

30 packets sent, 3% loss, min 4ms, max 3842ms, avg 727ms

There are currently just five clients attached and the issue affects them all. Hardware is a Ct2504K9 WLC running software 7.6.120.0. For some reason (incompetence...) I cannot find the model number of the AP in question in the WLC GUI, is it there?

This is a new network to me and is in a different country so only minimal local testing possible through a local non techie. Unfortunately I also only have read access to the devices at present. I am new to Cisco wireless but have plenty of experience in general R&S.

Thanks for your help!

Hi Ghaham,You have to log

Rasika Nayanajith — Thu, 16 Oct 2014 10:18:26 GMT

Hi Ghaham,

You have to log onto WLC (either GUI or CLI) & provide some more detail to help you.

In GUI, if you go to "wireless" tab you will see the AP information.

If possible SSH into WLC & get following information & attach it in next response.

1. show ap summary
2. show wlan summary
3. show wlan <wlan_id>
4. show client summary
5. show client detail <client_mac_address> For a client you have low performance.

HTH

WiFi is all about having a

George Stefanick — Thu, 16 Oct 2014 13:07:51 GMT

WiFi is all about having a mental check box. Is the wifi designed right. Is the wireless configured correctly. Is the clients configured correctly and optimized.

What are your 5 clients and are they on the latest driver ? Do they all behaving the same way ? Is your WLAN on both 2.4 and 5 Ghz? If so, move to 5 GHz only and test.

When I hear slow networks. First thing that comes to mind is channel utilization .. This is where you might have interference that causes a degraded network. This interference can be co-channel or non wifi.

I would also plug into the switch the APs are attached to. What is your response ? Same ?

Hello Rasika,Thanks for the

Graham Bell — Thu, 16 Oct 2014 13:31:05 GMT

Hello Rasika,

Thanks for the reply, AP is AIR-LAP1142N-E-K9, Primary Software Version 7.6.120.0 Boot Version 12.4.18.0 IOS Version 15.2(4)JB5$

The AP with the problem is MONAP01

The Client in the 'show client detail' output has the following response times:

monl3s01#ping 10.140.200.58 repeat 50

Type escape sequence to abort.
Sending 50, 100-byte ICMP Echos to 10.140.200.58, timeout is 2 seconds:

Success rate is 100 percent (50/50), round-trip min/avg/max = 1/360/1535 ms

Hi George,The clients are a

Graham Bell — Thu, 16 Oct 2014 13:42:42 GMT

Hi George,

The clients are a variety of devices of different type and brands. Some are not company owned. Unfortunately I don't have access to the site nor any meaningful way of doing any tests locally expect that which I can do via SSH/GUI on the WLC. I've posted below the results of show commands as requested by Rasika.

The AP concerned is plugged directly into the core site L3 switch, ping times to the AP itself are fine:

monl3s01#ping monap01 repeat 500

Type escape sequence to abort.
Sending 500, 100-byte ICMP Echos to 10.140.201.101, timeout is 2 seconds:

Success rate is 100 percent (500/500), round-trip min/avg/max = 1/2/17 ms

Graham

At this distance nose floor and slow rates should be expected. BTW this is what the AP hears the client at.

Hi Graham,Thanks for these

Rasika Nayanajith — Thu, 16 Oct 2014 17:37:56 GMT

Hi Graham,

Thanks for these output. As George pointed out this client is having poor signal indicating he is not close enough to an AP. Make sure you have proper coverage in first place (at least -75dBm).

Under SSID, I would disable AES option under WPA & TKIP option under WAP2. If all your client supports WPA2, then I would completely disable WPA. (Note that given client connect with WPA-TKIP & you will never get 802.11n rates unless client connect in WPA2/AES in 802.1X)

2. It looks like client connected at 5.5Mbps, which is a 802.11b data rate.

Current Rate..................................... 5.5

You should disable all 802.11b data rates (under wireless -> 802.11b/g/n-> disable 1,2,5.5 & 11 Mbps & make 12Mbps mandatory, leave other rates as supported)

Also in 802.11a/n band disable 6,9Mbps & make 12 Mbps mandatory & other rates as supported

3. Enable bandselect to prefer 5GHz over 2.4GHz for dual band support clients.

Band Select...................................... Disabled

4. Finally plan for a upgrade your WLC code to 7.6.130.0 as 7.6.120.0 is having lots of bugs & it is not a recommended code to be run. Here is the release notes for 7.6.130.0
