Wireless interface template

I state that I have recently approached Openwrt. I noticed that just installed, by default Openwrt has a virtual interface called LAN that relies on a bridge called br-lan between the eth0 physical ethernet interface and the wlan0 wireless interface.

This wireless interface called wlan0 has in the Network field the virtual interface called LAN mentioned above and is associated with the object radio0.

I would like to leave the default configuration, but only change the wlan0 wireless interface settings.

To do this from Openwisp, I created an Interface type template with the following fields:

Interface1: Wireless Interface

name: wlan0

type: wireless

autostart: yes

network: LAN

wireless: access point

mode: access point

radio: radio0

When I go to the AP, I find that another virtual interface called LAN has been created, basically a duplicate. In addition, the wlan0 wireless interface appears to be in WDS.

Why? Thank you

Hi,

Can you share the NetJSON configuration of this interface please?

Federico

Please see the concept of "attached network":

http://netjsonconfig.openwisp.org/en/latest/backends/openwrt.html#wireless-attached-to-a-different-network

This is the conf you should be using:

{
"interfaces": [
{
"wireless": {
"network": ["lan"],

]
}

Hi, I followed the given configuration but I had the following problems:

in Network \ Interface there is a virtual interface called WLAN0 for which there is the error: "Error: Network device is not present".

In Network \ Wireless the wlan0 interface which in Mode is set as Access Point (WDS) must be set as Access Point. How can I solve?

Thank you

I have no way to verify what you're saying.

I suggest you to proceed as follows: forget for a moment OpenWISP and focus on finding out the right OpenWRT configuration that works for the use case you need.

Once you have that, generate the same configuration via OpenWISP (check the generated configuration using preview).

What you say about WDS does not make sense because WDS is set to disabled explicitly, so there's likely an issue somewhere else.

@f.copano:

I am experiencing the same problem...

I have also followed the docs-section (http://netjsonconfig.openwisp.org/en/latest/backends/openwrt.html#wireless-attached-to-a-different-network) but this ends up in an orphaned interface.

The wifi is then assigned to the bridge and an interface consisting only of that wifi.

I have also tried configuring openwrt via luci and open it via netjsonconfig OpenWrt(native=open... but this gives errors like "...is not valid under any of the given schemas"

Is there any solution for this?

Dear AndyX90,

anything can be solved, if the steps to replicate the issue are described in detail, we may be able to help out.

Thank You Sir!

Okay, my AccessPoints are D-Link DAP-2610 with one single Port.
I am trying to accomplish the following:
They should have their only IP-Address on the default Lan-Bridge.
They should bridge multiple WiFi-SSIDs to different tagged vlans without having an interface in that vlan (proto none).
The wireless authentication takes place via radius through their "Management-Interface" on br-lan.

If i configure it via luci, it looks like the following:

network:

    config interface 'loopback'
        option device 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'

    config device
        option type 'bridge'
        option name 'WIFIBRIDGE'
        list ports 'eth0.13'

    config bridge-vlan
        option device 'WIFIBRIDGE'
        option vlan '1'
        list ports 'eth0.13:t'

    config interface 'WIFIBRIDGE'
        option proto 'none'
        option device 'WIFIBRIDGE'

OpenWISP generates the following config:

        option network 'WIFIBRIDGE'
        option port '1812'
        option server '10.10.10.10'
        option ssid 'MyRadiusWIFI'
        option wds '0'
        option wmm '1'

        option ssid 'MyRadiusWIFI'
        option wds '0'
        option wmm '1'

But there are the two "orphaned" Interfaces on top.
Note that luci generates switch-configs according to the new DSA-Style (https://openwrt.org/docs/guide-user/network/vlan/switch).

Also as i stated above, i tried to import a configuration from luci with netjsonconfig OpenWrt(native=open... but it errors that none of the schemas are matching...

Do you have any Ideas?

Thank You very much!

Hi there,

sorry for my late response, I forgot to reply to your questions.

OpenWrt 21 has changed the configuration format quite a bit, OpenWISP does not support this new format yet (DSA, new bridge syntax, "config device").
Since OpenWrt still supports to the old format, we have to stick to that one once the configuration engine of OpenWISP is upgraded.

If you don't know how to use the old format, I am afraid I can't help right now.
