Wireless Access

Hi,

I've a litte problem and I could not find the reason... I'm using an Aruba 3600 Controller with Software 6.1.2.4.

The voice clients have problems (there are all things configured for that such as WMM and so on). The client could stand 5 meters away from an AP and the Ping-Latenzy is up to 500 ms. I've checked the Way from Controller to the AP, all things fine.

I've searched for Multicast-Streams and so on, nothing to find. If the client makes a call, sometimes it works and sometimes when he moves on the voice quality is bad.

Don't know how 5 meters from an AP can resolute in those problems :-/

Are there any ideas what this problem could be? There are no interferences or something like that. The only strange thing is, that the client goodput is only 10 MBit/s. SNR is over 30, over 50... same thing on all Access-Points :-/

I'm using AP-93 with 2,4 GHz.

What voice protocol is the Alcatel phone using?

alcatel uses noe

Ok,

in this moment i have found the problem. After activation 802.11k the ping is below 100ms. After deactivation the ping is instantly over 400 ms.

How could that be?

Question:

Do other voice devices have such high latency on the same access point?  If not, please open a case with Alcatel to make sure you have the WLAN portion optimized.  If other devices do NOT have a latency issue, we have to troubleshoot interference, etc.

All devices was affected with this problem. After enabling 802.11k ALL devices did have pings under 100ms :-)

One checkbox for all clients :-)

What kind of encryption are you using on the AP and what are the devices are you using?

WPA2 PSK AES for the Voice-SSID and the Data-SSID

Open for Guest-SSID

You might want to open a case with Aruba about that to get to the bottom of this.  Very interesting..

You might have alerady solved this issue - but we discovered the similar issue with AOS 6.2.1.1 and 6.3.0.1 and Alcatel IP Phones.

The phones would NOT connect unless 802.11k was enabled, and after we enabled that reponse where terrible, and unable to place.

eliminated until we discovered that QuietIE advertising might have been the caveat here. Disabled that and response was rapid fast, enabled that and delay was immediate

to disable

wlan  rrm-ie-profile <prfofile-name>

no quiet-ie

to enable

wlan  rrm-ie-profile <prfofile-name>

no quiet-ie

And remember to add the rrm profile to the 802.11k profile connected to VAP for the wireless

show wlan virtual-ap

show wlan dot11k-profile (as mentioned in output above)

hello,

Alcatel 8118Voip model

we have many offices using  Aruba AP-207 without problem with this Phone, but on case of 214 and 204 AP this phone only works with 802.11 a or a/n

we need to solve in order to use with b/g/n as we did with AP 207
