Can't change the network ip address #53

I'm trying to set a custom network address, but unfortunately it never changes.

I'm running the access point using this command:
sudo ./lnxrouter --ap ap@wlan0 MyAccessPoint -p MyPassPhrase -g 10.10.10.10

When I look at my ip address, I have this:

4: ap@wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether e4:5f:01:5c:51:af brd ff:ff:ff:ff:ff:ff
    inet 192.168.4.1/24 brd 192.168.4.255 scope global ap@wlan0
       valid_lft forever preferred_lft forever
    inet 10.10.10.10/24 brd 10.10.10.255 scope global ap@wlan0
       valid_lft forever preferred_lft forever

The first one never changes, regardless of what I give in -g or even if i set -g.

I can ping 10.10.10.10 from the host itself, but not from a connected client.

Concerning the clients, they got an a dress in 192.168.4.0 too:

3: wlp59s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether a8:7e:ea:30:ad:09 brd ff:ff:ff:ff:ff:ff

What OS distro and version?
I guess there's another DHCP or some services running on your host .(Try find them and stop them first.)
Post the logs.

I'm running Ubuntu 18 on a raspberry pi 4

After searching for DHCP services I didn't find anything (I searched for lease file in /var/lib/dhcp but I don't have a dhcp directory, and I didn't find any services that looked like DHCP services)

Here are the lnxrouter logs:

What's the full command you ran?
Did you use --no-virt? Your log shows it did not create new virtual interface.

If that's true, ap@wlan0 must be created and was being handled by another service.

This is the full command I use:
sudo ./lnxrouter --ap ap@wlan0 MyAccessPoint -p MyPassPhrase -g 10.10.10.10

You're right, I've created a virtual interface myself using this command:
sudo /sbin/iw dev wlan0 interface add ap@wlan0 type __ap

I use this virtual device in order to still have wlan0 as a classic wifi client.

Moreover, this is maybe an other issue, but if I'm trying to run the hotspot with on wlan0, here is what I get (with logs):
sudo ./lnxrouter --ap wlan0 MyAccessPoint -p MyPassPhrase -g 10.10.10.10 --log-dns --hostapd-debug 2

It looks like two instances are run.

Regarding the errors in the logs (Failed to set interface 3 to mode 3: -16 (Device or resource busy)), I didn't find any process which could keep the interface busy, even if I stop the netplan service.

  1. Have you tried a virtual interface name without @? just letters only

  2. ss -tlunp list listening ports. Let's see what services probably running?

  3. If you run with a manually created ap interface while wlan0 as client , try some different --freq-band <GHz> and -c <channel> combinations. Ap and wlan0 having same or different channels.... See will that make some difference

  4. Since it is warning about imcompatible driver , which I'm afraid I can't help with. Maybe we can wait for some people's help

  5. It looks like two instances are run.

    The pid number tells only one instance was running. Two errors caused that message

Wow, using apwlan as an an interface name seems to work, I have my ip well set to 10.10.10.XXX, and so are the devices connected to it. Do you know what can cause this ?
In fact, apwlan0 works well too, but not ap@wlan

Just in case, here is the output of ss -tlunp:
