    Hi everyone,

    Does Udoo board support the "AP" mode to do a wifi access point with hostapd?

    Does someone can do the following commands to check:

    Code:
    $ sudo iw list
    $ sudo iwconfig wlan0 mode master
    Thanks !

    We're trying to do exactly the same thing with hostapd. A step by step tutorial will be available asap.

    Nice !

    How do you enable master mode on wlan0 ?

    I tested the following commands:

    iw list

    Hi,

    I could not wait! So I recompiled the kernel with support for iptables (.config here)

    The Access Point works fine with this configuration.

    However, the bridge mode of hostapd doesn't work. I would indeed replace my old "Fonera plus" which works as follows:

    Eth0 : Internet (dynamic IP) <<= NAT + DHCPD + DNSMASQ =>> br0 (Eth1 + wlan0) 192.168.1.0/24

    Any advice is welcome !

    Hi,

    I finally successfully set up a Wifi access point ( ethA > bridge [wifiB + usb ethC] ).

    Quick and dirty configurations files are available on https://gist.github.com/2xyo/8452047.

    Hi,

    I tried but can not build the driver - did you use the GUI Debian distri available via the UDOO site, the minimal system (unofficial) or did you build your own?
    If you have been using the release from the UDOO site, what have i to install first to build the driver?


    cheers

    Juergen

    Hi,
    I use the official (old) Ubuntu image :
    Code:
    # lsb_release -a
    No LSB modules are available.
    Distributor ID:	Ubuntu
    Description:	Ubuntu 11.10
    Release:	11.10
    Codename:	oneiric
    # uname -a
    Linux imx6-qsdl 3.0.35-2xyo-iptables-g76d54f2 #1 SMP Mon Jan 20 12:43:33 CET 2014 armv7l armv7l armv7l GNU/Linux
    
    You have to enable the support of iptables and recompile the Kernel Unico. Here is my .config.

    We're preparing a official UDOO OS (Ubuntu armhf) with hostapd already in it ;) Wait for it.
