WL-500g Deluxe Mod
Add Serial : http://wl500g.info/showthread.php?t=1993
J5 - RST, 3.3V, UART_TX/RX1, UART_TX/RX2



wl500gx_serial_pcb.pdf The difference between wl500g and wl500gx that the deluxe does not require a UART chip, so a simple RS232 transceiver will do. The parts you need:
- 1 MAX3232 IC (SO-IC)
- 5 1uF capacitors
- cables, connectors

You need to connect the router's 3.3v, GND, UART_TX0, UART_RX0 pins to the left side of the pcb, set the jumpers, and connect a DB9 connector to the right side. and..
J1 - USB_3, USB_4, GPIO1, GPIO5, GPIO7

VLAN configuration

LAN (vlan0), WAN (vlan1), DMZ (vlan2):
-vlan0ports="1 2 5*"
-vlan0hwname=et0
-vlan1ports="0 5"
-vlan1hwname=et0
-vlan2ports="3 4 5"
-vlan2hwname=et0
As of RC4, the switch is programmed and controlled by a set of switch modules (switch-core and switch-robo or switch-adm, depending on your hardware). These switch modules will create a /proc/switch/eth0, showing the current settings for the switch. The /proc/switch/eth0/vlan/0/ports is used the exact same way as the vlan0ports nvram variable, allowing you to change the switch settings in realtime.


Cisco-Linksys WRT54G
V1.0版，CPU型号Broadcom 4710 @ 125MHz，Flash=4M，RAM=16M，无线网卡使用Broadcom芯片的miniPCI卡
V1.1版，除了无线模块改用Broadcom integrated外，并且增加了JTAG接口，基本上无其它区别；
V2.0版，在V1.1版本上将CPU改为Broadcom4712@200MHz，并且板子上有串口和JTAG接口，支持VLAN；
V2.2版，在V2.0上将交换机芯片由ADM6996L(支持VLAN)改为BCM5325，无其它区别；
V3.0版，配置同V2.2；
V3.1版，CPU主频改为216MHz，其余同V3.0；
V4.0版，CPU改用Broadcom 5352@200MHz，CPU内集成了交换机芯片，这样就省掉了专门的交换机芯片，其余同V3.0；
V5.0版和V6.0版，Flash改为2M，RAM改为8M，其余同V3.0；（注意，Flash和RAM都小了，相当于配置降了）；
V7.0版，CPU与无线模块都与6.0不同，CPU内不含交换机芯片了，另外装了枚ADM6996，无线模块改用Atheros的了。
