 +====== Linksys WRV54G ======
  
 +The WRV54G is an X-Scale based 4-port router with WiFi support. The released firmware is based on Jungo's OpenRG.
 +Initial investigation was done by [[http://www.seattlewireless.net/LinksysWrv54g|Seattle Wireless]]. Another source of information is http://www.phj.hu/wrv54g/.
 +
 +Note that the WRV54G is known as a Gemtek GTW5715 when configuring the Linux kernel. Currently, the default OpenWrt configuration does include kernel support for this device. To use this device, an image must be built from the OpenWrt sources and use ''make kernel_menuconfig'' to select the GTW5715.

 +<WRAP box center 80%> {{:meta:icons:tango:48px-emblem-question.svg.png }} If you can **confirm** that OpenWrt is running on this device (i.e. you or someone else has **tested** it), please update the data accordingly. -> Click //View/Edit data//

 +
 +===== Installation =====
 +
 +Installation involves replacing the manufacturer's firmware (Bootloader and OS). 
 +
 +The bootloader will be replaced with a custom Redboot bootloader.
 +The OS you have to compile yourself :-). The WRV54G does not work with the stock builds avaible.
 +
 +To replace the original firmware you have three options:
 +  - Telnet (requires fw 2.03)
 +  - Serial (requires soldering)
 +  - JTAG (requires soldering)
 +
 +Telnet was disabled with firmware 2.10 and higer. Downgrade first. Simple feed te upgrade page from the web interface the older firmware. [[http://dl.dropbox.com/u/74388427/WRV54G/wrv54g_2.03_fw.rmt|wrv54g_2.03_fw.rmt]]
 +Please note that the above file was found somewere on the internets. It may not be safe to use outside a controlled envrionment. 
 +
 +  - Build your kernel and rootfs
 +  - Obtain a custom Redboot from here: http://mysite.verizon.net/jvasco/openwrt/rb-wrv54g-ROM.bin. 
 +  - Then follow the installation procedure described for [[toh:actiontec:mi424wr|Actiontec MI424-WR]].
