    This was very interesting you pointed out I named the “lan” as “br-lan” as seen in the ifconfig -a report I posted earlier.

    @Luciano-S said: For example, in your ifconfig from the Omega, you have a br-lan. In the tutorial i dont see a br-lan?! You have to be consequent with the naming. Otherwise it will never work.
    Why not?
    Because you named the lan "br-lan" and in the config of the Firewall it is named just "lan" !! Find the config file on the Omega and change it to the name as in the tutorial.

    There is nowhere in the tutorial, as you point out, where you are instructed to name a
    section “br-lan” and as a result nowhere did I do so. It is my theory this only appears as a function of the config -a command and not in any configuration files, whether it be network or firewall files.

    To quote me you have to write

    then it appears like that:

    If you don't find where you configured it the "br-lan", try in the firewall section to use "br-lan" !!

    By the way, I don't have all the equipment to do the tutorial ... but just from reading here i get chicken skin 😉

    @Luciano-S. Finding where I configured it, is impossible, as stated in my reply I never configured any file to carry the name "br-lan"
    As for trying to change the firewall configuration file from any setting carrying the "lan" name to "br-lan" hmm seems kind of arbitrary,
    but will done none the less.
    There are a couple of places where this shows up in the firewall configuration file as show below using
    <----change to br-lan to indicate where I changed in the firewall config file as you suggested.

    Below see notes where I changed "lan" to "br-lan" assuming that is what you meant. After which will post results. Fingers crossed.

    @Luciano-S tried and no success thanks for the ideas, though.

    @administrators Have decided to continue to experiment with this setup attempting to make it function. Have one last request before I do and that is could you post the network, wireless and firewall files used in the working session you have completed.

    Thank you.

    Now for the cleaning up of the procedure, more to come.

    Hi @Guest,

    I have done the Ethernet Bridge Tutorial (https://wiki.onion.io/Tutorials/Using-Omega-As-Wifi-Ethernet-Bridge) and enabled Internet access on my laptop (with its wireless radios turned off) via an Ethernet cable and the Ethernet Expansion. I am actually using the forum and writing this post using only said Ethernet connection. This procedure takes about 5 minutes.

    Full example /etc/config/network and /etc/config/firewall files are available in their modified and "ready" state here: https://gist.github.com/gbo-actual/ac79e9345a477b0024b368b292d4492b. The link to these files have been added to the tutorial above.

    Once you have updated the files, run the two commands in this specific order (or reboot the Omega):

    /etc/init.d/firewall restart
/etc/init.d/network restart

    And wait until it has finished (the command prompt will reappear). You can now plug in an Ethernet-capable device to the Omega (if it's your computer, disconnect from any wireless networks first).

    When acting as an Ethernet bridge, this disables the Omega's WiFi AP.

    @Gabriel-Ongpauco Thank you Gab, dropped your configuration files over mine (rebooted) and the connection continued to function. Would you post the wireless configuration file?
    Held off posting my solution due to one problem. When connecting laptop all works fine no problems can be found.
    But when I connect my Mole camera as the only device entering the ethernet expansion port it does not work.
    The Mole camera functions fine when I bypass the Omega and connect directly in my LAN switch.
    One test involved turning off the firewall but still no go.

    Agreed concerning turning off the wireless radio on laptop so to avoid alternative wifi connection screwing up the testing. Only using the hardwired ethernet connection on the laptop. As a test I unplug to make sure I am not getting signal from wifi as opposed to hardwired ethernet.

    @Guest said in Wireless setup:

    Does the cam not have a fix ip in a other range than the Omega?? If yes change it to something like 192.168.3.xx (xx) means a number outside of your DHCP range. Otherwise you can get difficulties when you have duplicated IP's.

    My laptop automatically receives all the settings needed to connect via DHCP setting on the laptop. The same settings were configured on the camera as stated before it handled the DHCP connection flawlessly while bypassing the Omega, connected to my LAN. So no, it does not have a fixed or static IP address.

    @Guest,

    The wireless file (I assume you mean /etc/config/wireless) was not changed during the tutorial and it should be fine to use from a factory reset if you need a fresh one. This is also where wifi login info is stored, so I cannot post mine.

    I suggest playing around more with your camera's setup and settings since as far as we can tell, the Omega is providing network access through the Ethernet Expansion and functioning normally.

    @Gabriel-Ongpauco Your assumption was correct the /etc/config/wireless file. FYI if you are stating your 'login info' is exposed I just comment over the top of it like:
    And one last request could you post the results from ifconfig -a from your setup? Thank you appreciate your help.

    @None-None With little or no knowledge dicided to try verbatim your suggestion.
    Started with a FACTORY RESET Omega.
    Then checked out the names of the interfaces which would be needed with the brctl command.

    Ran the ifconfig -a command and got the following:

    Seems like the wlan is not the correct entry, maybe at this point you can see what it is leading me astray?

    @Guest Hi, Thanks for explaining in detail. Is your tutorial will work for:

    Changing network priority between Ethernet and WIFI.

    1. Ethernet need to be at 1st priority.
    2. WIFI needed just as fallback network, If ethernet not working then search for WIFI connectivity
