Wireless setup

Guest

@Lazar-Demin Could you post how you tested the configuration and the files associated with this setup so i could do some comparisons?

Guest

@administrators after following the tutorial step by step for the 5th or 6th time and connecting my laptop to the ethernet port on the omega it fails to acquire the DHCP setting from my router. Same laptop connected directly to the router works fine? Any input or posting of files which made your connection successful would be appreciated.

Lazar Demin

@Guest Is your laptop setup to obtain an IP Address automatically from the DNS as mentioned in Step 4?
Can you check with another device that has an Ethernet port? Even another Omega + Ethernet Expansion will work.

All of the files on the Omega that have been modified are mentioned in the tutorial.

Guest

@Lazar-Demin Yes it is setup to automatically collect ip address (assuming you mention DHCP server).
And yes can move my ethernet expansion to my other omega and update.

Lazar Demin

@Guest Ok try your other Omega as well, but I meant try connecting the Omega Ethernet Bridge to another laptop or computer, just to make sure that it's not your laptop that's the issue!

Guest

When I connect the laptop to the network with out using the omega it obtains IP address just fine and can access the web.

Lazar Demin

@Guest Yes I figured your laptop can connect to your network just fine without the Omega...

What I was saying is using your Omega Ethernet Bridge with another laptop or computer. So we can find out if the problem is your laptop or the Omega!

Guest

@Lazar-Demin First computer tested was my laptop running windows vista it fails.
Second computer tested was my laptop Macbook it failed.

I do see this on the omega terminal window:

[ 8393.870000] eth0: link up (100Mbps/Full duplex)
[ 8393.870000] br-lan: port 1(eth0) entered forwarding state
[ 8393.880000] br-lan: port 1(eth0) entered forwarding state
[ 8395.880000] br-lan: port 1(eth0) entered forwarding state

But no connection can be made.

I remember to read in one of the Tutorials about using the Omega as router, you have to give access between the wireless and the network over the network adapter. But don't ask me in witch one!

Guest

@Luciano-S. Sorry Luciano but not sure what you are saying, so this my best guess.

The LAN and WLAN could be bridged on the omega in order for this to work and as per tutorial this is were he points out doing the following which I have incorporated into the configuration but still does not work.

CONFIGURE FIREWALL FILE
Step 3: Connect the Two Interfaces via Firewall Configuration
At this point you are asked to modify the /etc/config/firewall file as follows:
add;
line list network 'lan' to the firewall configuration file which I completed.

config zone
    option name     lan
    list   network      'wlan'
    list   network      'lan'    
    option input        ACCEPT
    option output       ACCEPT
    option forward      ACCEPT
	
	
REBOOT

Yes something like this I had in mind. You could do a ifconfig on the omega and post here.

At least the lan IP from the Omega should be in the same range as your Home-lan. I could imagine if this is not the same, you will not reach the DHCP Server from your network.

On a windows computer you can see the IP with ipconfig /all in terminal (cmd).

@Guest if you really need this so much ... you probably should think to hire someone who does this config for you.

@Luciano-S.
After running ifconfig -a on the omega configured as per tutorial: Using the Omega as a WiFi Ethernet Bridge
Here is what I got.

As for the IP from the Omega being in the same range as my home-lan that has occurred to me and thought as you did this was stopping the DHCP server from seeing the Omega. Tested this by changing the IP address in this section of the /etc/config/network file.

config interface 'lan'
   option ifname 'eth0'
   option type 'bridge'
   option proto 'static'
   option ipaddr '192.168.1.98'
   option netmask '255.255.255.0'
   option ip6assign '60'



The results from  running ifconfig -a:

The output from the ipconfig /all file did not show DHCP assigned address indicating it is not seeing the LAN side of the Omega.

As shown above DHCP is configured but the laptop is not getting assigned IP address.

As for needing this so much ....everyone loves a challenge and this is mine. Have been working on this a while keeping one eye on this board to see if anyone has figured out how to make this work and the other continuing to
test and experiment.

Luciano S.

@Guest you have to be more attentive. If you went trough the tutorial 5 or 6 times you have to go trough again and do what is written there.

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.

@Guest said:

Yes learning by doing is a good way to get further. But keep in mind that almost everyone is helping here for free and this without an obligation. So, for missing knowledge you have to give your self more time and should not force to much.

Guest

@Luciano-S. Going to review the steps in " Using the Omega as a WiFi Ethernet Bridge" verbatim, see if I can find your noted "br-lan" naming convention.
It would be appreciated if you posted your files when you went through the tutorial allowing me to see your results compared to the files I posted.
The focal point will be on the area you point out, I am interested as you are as to what created the "br-lan" section of the ifconfig -a report shown in my reply above.
Till then thank you and onward with the experimentation.

Showering accolades and kudos aplenty upon thee.

Guest

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.

Luciano S.

To quote me you have to write

@luciano said:
> my quotes ...

then it appears like that:
@luciano said:

my quotes ...

Luciano S.

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

Guest

@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.
