When you first start working with OpenWrt it can be very confusing, hopefully this will help you get started. This page is oriented to the VoCore, but only a few details are specific to a VoCore since it is a fairly standard OpenWrt installation.
First you need to realize that the VoCore is based on the development trunk of OpenWrt which means things are always changing, each day there is a new build available from OpenWrt.org and this is where the VoCore is configured to get software packages. My VoCore came with an image based on the Linux 3.10 kernel, the latest builds are using a 3.14 kernel so you can’t use the kernel module packages unless you upgrade the kernel too. There are several configurations out there, some have no default password, others have the password set to vocore, some set a default IP of 192.168.61.1 others are set to 192.168.1.1. Of course you can (probably will) change this but when starting if the password or IP address doesn’t work, try the alternative.
When you first power up your VoCore it will open a WiFi access point with a ssid of VoCore_xxxxxx, connect your computer, smartphone, tablet whatever to this AP and open a browser and connect to the Luci configuration page. To do this enter the IP 192.168.61.1 in the address bar, if 192.168.61.1 doesn’t work try 192.168.1.1. This will give you the login page, log in and set a password by dropping down the system menu and taking the administration option.
You can wander around here and look at what is available but one of the first things I did was connect the VoCore to my home wireless network. It is easy to make the VoCore unreachable through the WiFi at this point so be ready to hookup the USB/Serial adapter to be able fix things. The key to not needing the adapter in the following is to NOT apply the changes until the very end, use the Save button NOT the Save & Apply button!
Here is how I set my VoCore up:
1. Drop down the Network menu and select WiFi, push the edit button and in the General Setup tab under Interface Configuration enter your network name for ESSID, select client in the Mode drop down, check the box by create and enter wwan for the interface name.
2. Press the Save button (not Save & Apply!).
3. Switch to the Wireless security tab and select your encryption type in the Encryption drop down and enter you network’s passphrase in the key field, push the Save button again.
4. Drop down the Network menu and select interfaces. On this page press the add new interface button and enter wwan for the Name of the new interface and select DHCP client for the Protocol of the new interface and check the radio button by Wireless Network and press the Submit button.
5. There should be a box at the top that says Unsaved Changes, click on this, double check the settings (especially the ESSID and passphrase) and then click the Save & Apply button.
The webpage will sit there forever with a spinning wheel because the VoCore has shutdown it’s AP and connected to your home network. Go to your wireless router’s dhcp client list and find the ip for the new connection, this is the VoCore so enter it in the browser’s address bar and login to the VoCore with the password you set.
