Roaming Issue

Saravana_inflow — Tue, 22 Oct 2019 17:46:53 GMT

Hi. one of customer deploy the AP7632 in three floors. here using totally 15 Access Point. when roaming its not work properly. Eg. first Client connected to the ground floor AP, after he is moving to first floor. in that time client have some disturbing. once if we reconnect its work fine. please Suggest what did i mistake. I shared the Configuratioin backup.

Hi Saravana,

please use at least the WING 5.9.4.1

There are a lot of bugs before this version.

Regards,

Stefan

Also start with default rates before tuning. I think basic-mcs-1s is too optimistic for your environment..

Please upgrade to WiNG 5.9.6.0 and retest, we addressed many client connectivity issues in previous releases.

In addition to the above, here’s an article with some settings you may want to look at:

Recommended settings

Moreover, try grouping APs by floor per this article:

Group APs by floor

If trying this, please remove the ‘group-by area’ setting from the smart-rf policy.

I noticed that you’ve configured on channel on the 5GHz radio in the AP profile used by all APs:

interface radio2
channel 161ww
data-rates custom 6 9 12 18 24 36 48 54 basic-mcs-1s mcs-2s
wlan Tamara-SSID bss 1 primary

Please remove this setting and have smart-rf handle channel distribution per what is configured in the smart-rf rf policy.

Re: Roaming Issue

ckelly — Tue, 22 Oct 2019 21:41:19 GMT

In the AP’s main Profile, for the radios, you have this

interface radio2
channel 161ww
data-rates custom 6 9 12 18 24 36 48 54 basic-mcs-1s mcs-2s
wlan Tamara-SSID bss 1 primary
antenna-gain 15.0
aggregation ampdu max-aggr-size tx 65535
antenna-mode 3x3
antenna-diversity
airtime-fairness prefer-ht weight 10

Do you REALLY have a 15dBi gain antenna attached to these APs?
Also, the 7632 is not a 3x3 AP. It’s 2x2.
You have also enabled antenna diversity, which is not needed and should be disabled as per best practices.
I’d suggest not using an 80MHz wide channel. Use 20MHz or 40MHz
If AP coverage is good, recommend using these data rate settings
- data-rates 5GHz custom basic-12 18 basic-24 36 48 54 basic-mcs-1s mcs-2s

On the 2.4GHz radio, you have:

interface radio1
wlan Tamara-SSID bss 1 primary
aggregation ampdu max-aggr-size tx 55535
antenna-mode 3x3

Again, remove the 3x3 antenna-mode setting.
Again, if AP coverage is good, recommend these data rate settings:
- data-rates 2.4GHz custom basic-12 basic-24 36 48 54 basic-mcs-1s mcs-2s

In the SmartRF Policy, you have:

smart-rf-policy default
group-by area
group-by floor
sensitivity custom
assignable-power 5GHz max 18
assignable-power 5GHz min 10
assignable-power 2.4GHz max 18

smart-ocs-monitoring extended-scan-frequency 5GHz 0
smart-ocs-monitoring extended-scan-frequency 2.4GHz 0
interference-recovery client-threshold 255
interference-recovery channel-switch-delta 5GHz 5

coverage-hole-recovery coverage-interval 5GHz 5
coverage-hole-recovery coverage-interval 2.4GHz 5
interference-recovery channel-hold-time 180
neighbor-recovery dynamic-sampling retries 2

Recommend changing the channel width to 20 or 40MHz
Recommend changing the sensitivity from “custom” and just use “medium” setting.

In the WLAN Profile, you have:

wlan Tamara-SSID
description 173 Residence
ssid "173 Residence"
vlan 1
bridging-mode local
encryption-type ccmp
authentication-type none
wireless-client inactivity-timeout 54000
fast-bss-transition
wpa-wpa2 psk 0 12345678
data-rates 2.4GHz custom 1 2 5.5 6 9 11 12 18 24 36 48 54 basic-mcs-1s mcs-2s mcs-3s
data-rates 5GHz custom 6 9 12 18 24 36 48 54 basic-mcs-1s mcs-2s mcs-3s mcs-4s

Recommend disabling the ‘fast-bss-transition’ setting. This might be the cause of the problem your clients are having roaming. Some clients do not properly handle 802.11r.
