 +
 +^ CPU ^ Ram ^ Flash ^ Network ^ USB ^ Serial ^ JTAG ^
 +| MIPS 24KEc V4.12 | 32MB | 4MB | 5x100mbps | No | Yes | Yes |
 +
 +==== WAP3205 ====
 +
 +**NOTE:** These informations refer to the WAP3205 **NOT** WAP3205 v2 which seems to have different hardware!
 +
 +The board is the same one used on the NBG-419N, but has 2 Ethernet ports instead of 4 LAN + 1 WAN. (and has no WiFi on/off switch)
 +
 +The images for the NBG-419N are compatible with the WAP3205, as they have same hardware internally.
 +
 +**NOTE:** when configuring the switch or VLANs, currently OpenWRT lets you setup or tag 5 ethernet ports since internally there are 5 ports on the switch, but only 2 are wired to physical ports!

 +====== Installation ======
 +
 +Support appeared in r28078. ​
 +The prefered method is to build the image by yourself. See [[doc:​howto:​build]]. Select ''​Ralink RT288x/​RT305x''​ as ''​Target System''​ and ''​RT305x based boards''​ as ''​Subtarget''​ in ''​make menuconfig''​.
 +If you dont like to build the image by yourself, you can download recent OpenWrt at https://​downloads.openwrt.org/​ . In the directory /​ramips/​rt305x/​ you would find a file named like ''​...rt305x-nbg-419n-squashfs-sysupgrade.bin''​ . 
 +
 +Unfortunately,​ the firmware cannot be installed by factory web configuration utility. Someone may try to build the sources from ftp://​opensource.zyxel.com/​NBG-419N to check what is needed for it. 
 +
 +Follow the manual for installing OpenWrt via TFTP: [[doc:​howto:​generic.flashing.tftp]]
 +
 +Open the case, connect a TTL-to-RS232 converter cable (not the standard serial cable!) - see [[doc/​hardware/​port.serial]]. You can also use a USB to TTL Serial Cable. See image below for connection.
 +
 +Port speed is 57600, 8 databits, no parity, 1 stopbits, both hardware and software flow control must be disabled. The router sometimes does not power on when serial cable is connected, so you have to try some times or make the serial connection after powering on.
 +
 +If you miss the bootloader (U-Boot) prompt, wait until ZyXEL Linux boots and issue ''​halt''​ or ''​reboot''​. When you see U-Boot prompt, press 2:
 +
 +  Please choose the operation:
 +   1: Load system code to SDRAM via TFTP.
 +   2: Load system code then write to Flash via TFTP.
 +   3: Boot system code via Flash (default).
 +   4: Entr boot command line interface.
 +   6: To emergency.
 +   9: Load Boot Loader code then write to Flash via TFTP.
 +
 +  You choosed 2
 +
 +Put ...ramips-rt305x-nbg-419n-squashfs-sysupgrade.bin to your TFTP server root (usually ''/​var/​lib/​tftpboot''​ on Linux) and start the TFTP server. U-Boot did not like such a long file name, so rename ''​...ramips-rt305x-nbg-419n-squashfs-sysupgrade.bin''​ to for example ''​openwrt.bin''​. Connect one of the router'​s LAN ports and TFTP server to the same LAN.
 +
 +Then press Y and enter IP for your device, TFTP server and firmware image file name:
 +<​code>​
 +  2: System Load Linux Kernel then write to Flash via TFTP. 
 +  Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N)
 +  Please Input new ones /or Ctrl-C to discard
 +    Input device IP (192.168.1.1) ==:
 +    Input server IP (192.168.1.10) ==:
 +    Input Linux Kernel filename (openwrt.bin) ==:
 +</​code>​
 +
 +U-Boot should sucessfully flash and then boot the new firmware image.
 +
 +Its recommended to flash the same sysupgrade firmware file once again with the build in OpenWrt updater and to not save the settings. The TFTP in U-Boot sometimes mess up few parts in the firmware.
