Dear 

How can i turn on band streeing feature on 88W9098 chip

Thanks

Dear @ocourson 

Can you tell us who is the end customer name ?

==> Sorry i can't, the project is developing now. 

- host used (NXP i.MX model, other)

==> host is other ARM basse system not I.Mx model

- host interface used for wifi, and interface used for BT (if used)

==> uap0 and muap0, we don't use BT

- host OS and OS version

==>OpenWRT 

- Wifi driver version

==>17.68.1.p109.2-17.26.1.p109.2

I don't understand why the host you run will affect band steering feature?

the band steering is the WIFI chip feature isn't it?

Dear @AllenHsu2 

Band steering feature is not included in all the SW releases, so this is the reason why we need to know which SW version you are using (and host interfaces used, as SW releases depend on this).

Band steering is supported in the FP68 SW release you are using (17.68.1.p109.2-17.26.1.p109.2)

As explained in the README_MLAN file, band steering is enabled by:

- copying a band_steer_cfg.conf file to /lib/firmware/nxp/

Example config file can be found in FP68 release (wlan_src/config/band_steer_cfg.conf)

- adding the following moal.ko parameter driver parameter (or in wifi_mod_param.conf) : "band_steer_cfg=nxp/band_steer_cfg.conf"

Hi @ocourson 
Thans for your sharing the information,

We're using the AP mode not client mode, can i use the same way to enable band steering feature?

After checking the README_UAP.txt, it seems that  I only to do is to issue 

uaputl.exe band_steering_cfg 1

Is there any thing i need to do?

thanks 

[ocourson]

Dear @AllenHsu2 

I believe the band sterring is only AP mode

 "uaputl.exe band_steering_cfg 1" is enough to enable the feature.

Then you can use moal.ko driver parameter (band_steer_cfg=nxp/band_steer_cfg.conf) if you need further configuration.

Hi @ocourson 

Thanks for your great information, Is there any document which describe the folloing configuration?

If  i don't need to block STA by mac, Can i just delete the section 2 ?

Dear @AllenHsu2 

I could not find any other documentation explaining that configuration, apart from the comments provided inside the configuration file example.

If you do not use STA MAC addresses filtering, I think you should keep at least:

# STA MAC addresses for blacklisting
# Max number of MACs supported is 20
pattenHeaderType:2=0x0137
patternHeaderLen:2={
Type:1=0 #Type 0 for Blacklisted MAC Addresses
BlacklistState=0 # for disable blacklisting

}

Dear Allen,

Can you tell us who is the end customer name ?

Can you also provide the following customer setup details ?

- host used (NXP i.MX model, other)

- host interface used for wifi, and interface used for BT (if used)

- host OS and OS version

- Wifi driver version

Regards,

Olivier

Dear @AllenHsu2 

Could you please provide the details we asked two weeks ago ?

We need that information to provide you the correct answer, as band steering feature is not supported by all SW releases.

Regards,

Olivier
