Wireless setup

Lazar Demin

@Guest very legible now, thanks!

Nayan

@Guest... Just curious whether you were able to get it working finally... ?

Guest

@Nayan Still reviewing my files and attempting to get it working. In case there was a problem with the cables or laptop used a different set of components still fails. Can you see from the information posted if I have miss-configured anything called out in your tutorial? Have you successfully had this work on your end?
Will go over the steps you call out again and see if there is something I am missing.

Guest

@Nayan read your step by step instructions and took some notes following each step and checking it off but still could not get it to work could you review my steps and see where I am going wrong?

Step 1: Connect Omega with WiFi
Pretty straight forward using the gui for this setup portion.
Step 2: Enable the Ethernet Connection in Omega
Basically what we need to do is to uncomment the following part licated at /etc/config/network:

config interface 'lan'
	option ifname 'eth0'
	option type 'bridge'
	option proto 'static'
	option ipaddr '192.168.3.1'
	option netmask '255.255.255.0'
	option ip6assign '60'

Step 3: Connect the Two Interfaces via Firewall Configuration
There is another tutorial (as I said), click here.
This tutorial is how to make Omega as a router.
The theory is the same, all we need to do is to convert
what is going on in the tutorial.
Step 3a: Turning the Omega Into a WiFi Router
Open up the /etc/config/network file, and add the following line at the end of the file:

config interface 'wan' 
	option ifname 'eth0' 
	option proto 'dhcp'   
	option hostname 'OnionOmega'

Then restart netowrk /etc/init.d/network restart
Step 3b: Step 4: Configuring the WiFi Settings
Next, you will need to open up the /etc/config/wireless file and configure two things.
First, you should disable the WiFi network that the Omega is currently connected to.
You can do this by deleting or commenting out a block that looks something like the following:

 config wifi-iface
	option device 'radio0'
	option mode 'sta'
	option network 'wwan'
	option ssid 'WiFi Network'
	option encryption 'psk2'
	option key 'TopSecret'
	option disabled '0'

Next, you might want to configure the WiFi network that the Omega will be serving.
You can do this by editing the following block:
Within this block, you can change the SSID of your Omega,
as well as the type of encryption you want to use for the router.
NOTE CHECK ON ENCRYPTION USED ON LAN COMPARE TO ENCRPTION SET ON OMEGA

    config wifi-iface
	option device 'radio0'
	option network 'wlan'
	option mode 'ap'
	option encryption 'psk2'
	option ssid 'OmegaRouter'
	option key 'RouterPassword'

Once you have finished customizing the WiFi network, simply save and close the file,
and run the following command to restart the WiFi network:
wifi
Step 3C: Enabling Packet Routing

Next, you will need to open up the /etc/config/wireless file and configure two things.
First, you should disable the WiFi network that the Omega is currently connected to.
You can do this by deleting or commenting out a block that looks something like the following:

config wifi-iface
	option device 'radio0'
	option mode 'sta'
	option network 'wwan'
	option ssid 'WiFi Network'
	option encryption 'psk2'
	option key 'TopSecret'
	option disabled '0

'Next, you might want to configure the WiFi network that the Omega will be serving.
You can do this by editing the following block:
Within this block, you can change the SSID of your Omega,
as well as the type of encryption you want to use for the router.
NOTE CHECK ON ENCRYPTION USED ON LAN COMPARE TO ENCRYPTION SET ON OMEGA <---my comment

config wifi-iface
	option device 'radio0'
	option network 'wlan'
	option mode 'ap'
	option encryption 'psk2'
	option ssid 'OmegaRouter'
	option key 'RouterPassword'

Once you have finished customizing the WiFi network, simply save and close the file,
and run the following command to restart the WiFi network:

wifi

Step 3C: Enabling Packet Routing
Next, you will need to configure the Omega to route packets from the ethernet interface
(eth0) to your WiFi interface (wlan0). To do this, you will be editing the /etc/config/firewall file:
find the the block that looks something like the following:

config zone
	option name     		wan
	list   network      'wwan'
	#list   network     'wan6'
	option input        ACCEPT
	option output       ACCEPT
	option forward      ACCEPT
	option masq     1
	option mtu_fix      1

and add the following line:

list   network      'wan'

What you will end up with is something like the following:

config zone
	option name     		wan
	list   network      	'wwan'
	list   network      	'wan'
	#list  network     		'wan6'
	option input        	ACCEPT
	option output       	ACCEPT
	option forward      	ACCEPT
	option masq     		1
	option mtu_fix      	1

What this tells the Omega to do is to add the wan network
(which we defined in /etc/config/network file)
to a firewall zone called wan.
This zone has already been setup to route packets to another firewall zone
called lan, which contains the wlan0 interface.

Once you have saved and closed the file, run the following command to restart the firewall with the
updated configuration:

/etc/init.d/firewall restart

Once we understand what is going on, we can modify the file. What we are actually doing is to add a single line
of configuration under zone lan.

list   network      `lan`

list means access list, you can get the information through Openwrt Firewall configuration page.

Now, the configuration looks like this:

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

Now we need to restart the service, by doing /etc/init.d/firewall restart and /etc/init.d/network restart
(firewall goes first), or simply reboot Omega.
Step 4: Connect to Lan Switch via Ethernet
Since we configured all the things, and restarted the service, now we should be able to connect with other
devices via ethernet. Unfortunately, Onion does not provide an tutorial about how to connect my laptop to Omega.

Make sure that your connection is set to Obtain IP address and DNS address Automatically. It should be set so by default.

Using this Setup
If you have a device that only can be connected via Ethernet and you only have WiFi available, you could apply this tutorial to make it work!

@Guest erm... is this just the tutorial from https://wiki.onion.io/Tutorials/Using-Omega-As-Wifi-Ethernet-Bridge pasted into the forum???

Guest

It is actually the combination of two tutorials showing the steps taken to achieve the end result. Posted in an effort to share with @Nayan my exact steps taken as well as using it during my setup as a check off sheet. When carrying out the tutorial it was helpful to see the actual steps rather then links to other steps. As of now have not successfully completed this setup configuration and @Nayan might find it useful to trace my steps and see why it has failed.

And you want me to uninstall wpad-mini and installing wpad, correct?

Nayan

Yes... Please try that

Guest

@Nayan ran opkg update, then ran opkg remove wpad-mini all ran fine but when I tried opkg install wpad got:

root@Omega-xxxx:/# opkg remove wpad-mini
Removing package wpad-mini from root...
root@Omega-xxxx:/# opkg install wpad
Unknown package 'wpad'.
Collected errors:
 * opkg_install_cmd: Cannot install package wpad.

Guest

@Nayan did the opkg update it ran no problem then after the uninstall of wpad-mini and attempt to install wpad no longer had connection.
Now when i run opkg update get a:

Collected errors:
 * opkg_download: Failed to download http://downloads.openwrt.org/chaos_calmer/15.05.1/ar71xx/generic/packages/base/Packages.gz, wget returned 4.

When i run opkg update on my other Omega it runs fine?

Guest

For those wondering why this sounded incomplete including our discussion via chat.

Guest a day ago
Any word on the fail of bridge posted my network file for your review
Nayan about 3 hours ago
Hey Guest... sorry have been busy with something... Everything seems legit... I have one last thing you can try (cos it worked for me)... try installing wpad removing wpad-mini... though I do not know the exact circumstance for your network it certainly wont harm ur omega to have the full version of wpad... give it a shot and let me know... in the meantime let me see the config again...
Nayan about 3 hours ago
Hey guest... I just noticed something...in your '/etc/config/wireless' file just change the 'wlan' to 'wan' and let me know the results
Nayan 27 minutes ago
hi there Guest... yes please do those two things and see if it works
Guest 22 minutes ago
root@Omega-xxxx:/# opkg install wpad
Unknown package 'wpad'.

U need to uninstall the wpad-mini first
do an ifconfig to check if you are connected to the internet first
Nayan 4 minutes ago
thats really strange...
Guest 3 minutes ago
Yup did uninstall wpad-mini before attempting to install wpad
Nayan 3 minutes ago
do you mind doing a factory reset?
Guest 2 minutes ago
will do and let you know
Nayan 2 minutes ago
had to do factory reset several times
ok

@Nayan was curious so checked my other Omega with the most current firmware and here is what I got:

wpad - 2015-03-25-1 - This package contains a full featured IEEE 802.1x/WPA/EAP/RADIUS Authenticator and Supplicant
wpad-mesh - 2015-03-25-1 - This package contains a minimal IEEE 802.1x/WPA Authenticator and Supplicant (with 802.11s mesh and SAE support).
wpad-mini - 2015-03-25-1 - This package contains a minimal IEEE 802.1x/WPA Authenticator and Supplicant (WPA-PSK only).

It appears you don't have to download and install as they are already present just not sure if they all are loading concurrently?

Guest

@Haoran-Li followed your tutorial but can not get this to function would you be so kind to review my steps and see if something I did was incorrect?

Guest

@Lazar-Demin @Haoran-Li Never got this to work have you had time to review my steps and help me out?

Guest

Can I get some help with this please.

Guest

@Lazar-Demin said:

@Guest In the post with all of the configuration files, can you please edit the post to format the settings with code syntax? It's incredibly hard to read with the current formatting.
There's a guide here: https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet#code

I'll ask @Haoran-Li to take a look, meanwhile you should experiment as well, we definitely welcome innovation in the community

Do you have an update for me on this procedure did I derail following the instructions? Have not heard from Haoran.

Lazar Demin

@Guest Hoaran's co-op term with Onion has ended. We're hoping to get him back in the fall for another co-op term

In the meantime, we've tried following the tutorial from the beginning with a factory restored Omega and it worked as expected. So we've confirmed the procedure is correct.

Please try a factory reset on your Omega and try the procedure from the tutorial again. We can provide tutorials and general advice, but we simply do not have the resources to debug cases on an individual basis.
