The 5G band steering doesn't works.

[zlinuxboy]

I have been read a lot of posts here and materials about how to encourage client to associated 5G radio, but failed.

these are the config:

additional settings - optional settings

1. turnoff 2.4Ghz 1-24, set 36 to be basic

2. turnoff 5Ghz    1-18, set 18 to be basic

radio profile
3. ng0_clone 2.4Ghz
 deny-client: 80211b
 maximum transmit power: 10
 band-streeing: encourage 5 ghz band usage
 number of connection attempts from 2.4Ghz client to ignore before responding: 3
 weak signal probe request suppression: off
 safety net: off
 enable frame burst: off
 enable short guard interval: on
 enable aggregate mac protocol data units: on
 enable VHT for 2.4Ghz: off

2. ac0_clone 5Ghz

 maximum transmit power: 14
 number of connection attempts from 2.4Ghz client to ignore before responding: 3
 high density configuration: off
 client load balancing: off
 radio load balancing: off
 weak signal probe request suppression: off
 safety net: off
 enable frame burst: on
 enable short guard interval: on
 enable aggregate mac protocol data units: on
 enable transmit beamforming: on

but the nearly half of clients choose to associated 2.4Ghz band, how to solve this problem?

thanks @Sam Pirok , I disable 2.4 on same ap, and change the 2.4G tx power to 5 and going to observe the effect. I have another quesiton.

`show int wifi1` has CRC error rate, but `show int wifi0` doesn’t have it. how to check the CRC error rate of wifi0?

@Sam Pirok look at the preview comments. the 2.4G’s Summary state=High collision, that is the reason I would like to encourage clients to 5G.

Without a support contract you would not be able to open a case. You can adjust the power level on the AP by going to Monitor> Devices> Click on the blue host name of the AP> Choose Configure on the left hand side menu> Go to Interface Settings> Scroll down to the Transmission Power section, change this to manual if it isn’t there already, then use the slider bar to set the power level from 1-20dBm. 

You could also try disabling 2.4Ghz on some APs depending on how many APs you have broadcasting. That would leave the 2.4GHz signal for devices that can’t use 5GHz, but at the same time it will make the 2.4GHz signal significantly weaker than the 5GHz signal.

Is there a particular reason you don’t want clients on 2.4GHz?

well, there is another question, how to change the tx power level below 10? It seems the xiq do not allow to do that.

Hi, ash

the tx power level of 2.4 is 10, and 5 is 14.

yes, of coz, those client which associated with 2.4 are capable of 5Ghz except this one 3402:86aa:4042
