 +======= T-Home Speedport W 303V  =======
 +The T-Home Speedport W 303V is a IAD sold by T-Com with a ADSL2+ Annex B Modem, 11n Wifi and two FXS ports as well as a S<sub>0</sub> bus connector.
 +There are 2 models of it, "Typ A" and "Typ B" having completely different hardware.
 +[[spw303v|Click here for "Typ A"]].

 +====== Typ B ======
 +
 +^ CPU ^ Ram ^ Flash ^ Network ^ USB ^ Serial ^ JTag ^
 +| Broadcom BCM6358@300MHz | 32MiB | 8MiB | 1 + ADSL | No | Yes | No |

 +
 +==== Opening the case ====
 +
 +  * To remove the cover you have two remove two screws, then open a total of eight plastic clips. These are very easy to break.
 +
 +==== Serial ====
 +-> [[doc:hardware:port.serial]]
 +
 +The Speedport W 303V comes pre equipped with a serial header with 3.3V TTL. The serial console is available on J3
 +
 +<code>
 +serial connector J3
 +
 +      |---|
 +      | o | GND
 +      | o | RX
 +      | o | TX
 +      | o | 3.3V
 +      |---|
 +
 +  <Ethernet/RJ45 Ports are on this side>
 +
 +</code>
 +
 +The serial port is the typical 3.3V TTL serial commonly found on router and router-like devices, NOT a PC-style RS-232 serial, with it's different signaling voltages. It's 115200 8-N-1 without hardware or software control.
 +
 +
 +
 +
 +===== Installation =====
 +  - -> [[doc:howto:obtain.firmware]]
 +  - -> [[doc:howto:generic.flashing|Install OpenWrt]]
 +
 +==== OEM easy installation ====
 +
 +This section deals with how you install OpenWrt from a device freshly opened.
 +  * Configure your PC to use an IP from 192.168.2.0/24 (not .1)
 +  * Press and hold reset, power on the device
 +  * Wait until all leds are lit, then stop pressing reset
 +  * Browse to http://192.168.2.1
 +  * Upload openwrt-SPW303V-squashfs-cfe-**factory**.bin file to router
 +  * Wait for it to reboot
 +  * Telnet to 192.168.1.1 and set a root password, or browse to http://192.168.1.1 if LuCI is installed.
 +
 +**NOTE:** If you are using this to recover from a non working flash, you have to first upload a stock firmware using the same procedure, then flash OpenWrt.
 +
 +==== Upgrading OpenWrt ====
 +->  [[doc:howto:generic.sysupgrade]]
 +
 +If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the sysupgrade command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
 +
 +**Note:** You need the -**sysupgrade**.bin file for upgrading.
 +
 +=== LuCI Web Upgrade Process ===
 +
 +  * Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL
 +  * Upload image file for sysupgrade to LuCI
 +  * Wait for reboot
 +
 +=== Terminal Upgrade Process ===
 +
 +  * Login as root via SSH on 192.168.1.1
 +  * Use the following commands to upgrade.
 +
 +<code>
 +cd /tmp/
 +wget http://downloads.openwrt.org/attitude_adjustment/12.09/brcm63xx/generic/openwrt-SPW303V-squashfs-cfe-sysupgrade.bin
 +sysupgrade openwrt-SPW303V-squashfs-cfe-sysupgrade.bin
 +</code>
 +
 +===== Basic configuration =====
 +-> [[doc:howto:basic.config|Basic configuration]] After flashing, proceed with this.\\
 +Set up your Internet connection, configure wireless, configure USB port, etc.
 +
 +
 +===== Specific Configuration =====
 +==== Interfaces ====
 +
 +The default network configuration is:
 +^ Interface Name ^ Description ^ Default configuration ^
 +| br-lan | LAN & WiFi | 192.168.1.1/24 |
 +| eth0 | LAN port | None |
 +| wl0/wlan0 | WiFi | Disabled |
 +
 +==== WLAN ====
 +Installation the proprietary Broadcom drivers
 +
 +<code>opkg install kmod-brcm-wl wlc</code>
 +
 +==== Failsafe mode ====
 +-> [[doc:howto:generic.failsafe]]
 +
 +==== Buttons ====
 +-> [[doc:howto:hardware.button]] on howto use and configure the hardware button(s).
 +
 +The Speedport W 303V has two buttons. They are Reset and Secure Easy Setup. Here, we merely name the buttons, so we can use them in the above Howto:
 +^ BUTTON ^ Event ^
 +| Reset | reset |
 +| Secure Easy Setup | ses |
 +
 +there is a problem with the latest trunk - feb 2014 . the router always boot into failsafe - caused by the button config.
 +take a look at https://dev.openwrt.org/ticket/14546
 +
 +===== Debricking =====
 +-> [[doc:howto:generic.debrick]]
 +
 +The bootloader (CFE) has a web interface for uploading firmware images.
 +Press your reset button while powering up the device, wait ~20seconds, then release the reset button. All LEDs should light.
 +Your device will be accessible on the http://192.168.2.1 address with a very simple webpage where you can upload a new image.
 +The device will not start a DHCP server, you will have to configure your host to the 192.168.2.x subnet.
 +
 +Ps. do not try to upload images with TFTP using the flashimage command in your CFE prompt, because it does not works.
 +
 +===== Notes =====
 +
 +The Bootloader (CFE) is password protected. To abort autoboot you have to either hold the reset button long enough to enter recovery mode or enter ''TCO&'' when it counts down for autoboot.
 +
 +===== Tags =====
