Usteer high broadcast traffic rate port 16720

Installing and Using OpenWrt Network and Wireless Configuration

When debugging broadcast traffic to improve airtime, I noticed high rate of traffic (3 req/sec) from 192.168.1.1:16720 --> 255.255.255.255:16720 for usteer

The impact of high broadcast traffic is increased airtime utilization (reducing capacity), which increases collisions and latency for other senders.

to debug your usteer traffic, use this tcpdump command

 tcpdump -i br-lan port 16720

To reduce this , I added the following configuration . In general I increased the "interval" values by 2-5x

config usteer
        option network 'lan'
        option syslog '0'
        option local_mode '0'
        option ipv6 '0'
        option debug_level '1'
        option local_sta_update '10000'
        option max_retry_band '3'
        option remote_update_interval '10000'
        option roam_scan_interval '20000'
        list ssid_list 'xxxxx-x01'
        option load_kick_min_clients '25'
        option initial_connect_delay '100'

You can set network to 'loopback' and local_mode to 1.

You can set network to 'loopback' and local_mode to 1.

can you explain how that works? i do need steering to broadcast to my SSID for the clients to receive it , right?

Read your post for reference. No, you do not need to broadcast anything to clients.

5

I read it and the combo was unclear . Please explain your suggestion and how it will help

6

No idea what you mean.

7

Why are you proposing those changes ? Explain

8

To zero generated ip traffic.

thanks for clarifying, but how does usteer send out steering signals without IP traffic? is there another radio non-IP signal sent out? and what's the purpose of the IP traffic?

Make a management interface on each ap and have the ap's communicate via that.

that's a good tip, but how to configure the usteer signals to client stations ? This is for steering 2.4g to 5g

Well, no IP and communivation happens, call it magic or read history books.

You don't need to worry about this, it goes via hostapd on the interface that the clients connect to
