In the hardware section of my previous post, I forgot to say that the ground of the transistor circuit is connected to Pin 5 (the ground pin) of the DB9 RS-232 connector.

2. If you put the circuit board on a table so that the WAN and LAN connectors are facing you, power socket on your right, and the antenna on your left, then the 5 pins, from left to right, are Unused, Transmit, Receive, and Vcc (3.3VDC).
>>Hi, DuneBuggy,
In your step2, can we do it by a normal usb-ttl serial cable? I found there's nothing showed up by my usb-ttl cable...
I just got one smcwbr14s-n4 and flashed it with firmwares of the above, but I can't get universal repeater worked, there's no wan ip after setting it to "repeater mode", any advice would be appreciated.

The SMC Barricade N uses Ralink hardware, has a 4MB flash chip, and 4MB RAM. IThe Barricade is not listed on the supported devices, but honestly, I bought it for $20, and it can't do bridge functions like I thought which makes it less than useless for me, so I kind of just want to attempt to flash it and install, with the full understanding that it might brick it. Where can I download the generic Ralink installation?
>>Hi, Arthur,
I just followed your steps on my smcwbr14s-n4,but failed to configure it as a repeater, have you tired it on repeater mode ? there's no wan ip generated though.
I think now you can contribute with sending bricked device to DDWRT team
I will also try flash my device, so maybe I will be the second
Btw did you use the binary for tftp flash or for webflash ? I guess for webflash. Unfortunatelly you can use only tftp method to flash this smc router. It was mentioned before.
FYI: I was able to successfully TFTP both the 2013 image mentioned previously, and the latest beta build (r27490 2015-Jul-06). I cannot yet speak to the stability, but so far so good.
I already had a USB/TTL adapter lying around with jumper cables, so it was actually trivial to connect since the header on the router already has pins. Connected gnd/rx/tx and 115.2k and good to go.
I didn't bother replacing the IP address, I just set my computer to 10.10.10.3 and downloaded tftpd32 and easy peasy.

Today, I had to reflash my smcwbr14s-N4 SMC router, needed the instructions I posted on Jan 22, 2014, 6:59, and discovered that Step 2 had an omission in the pinout for serial communication. From left to right, the pins are Unused, Ground, Transmit, Receive, and Vcc (3.3 VDC). (In my post, I accidentally omitted "Ground".) So sorry if this messed anybody up!
Reply to vkjuju: I have never used a USB-TTL device; so, I don't know how to make that work.
Reply to chienbinhso13: I made the same mistake and "bricked" my smc after web-flashing with the Nov-13-2015 Senao-ESR9752SC-webflash.bin. I followed my Jan 22, 2014, instructions and got it working again using firmware.bin.
