That is the first pinout I've seen that way. I went with the pinout here:
http://wiki.openwrt.org/toh/buffalo/wzr ... ial.pinout
which was the same as the one here:
http://www.dd-wrt.com/phpBB2/viewtopic.php?p=434920
I also just verified that I am seeing 3.3vdc between pins 1 and 2 so it appears that I am, indeed, using the correct pinouts.
Thanks!

How do you connect it to your computer?

Re: WZR-HP-G300NH-R Fail
Hmm, not familiar with Minicom myself
I usually use Putty thru Windows to connect via a
USB to Serial adapter
115200,n,8,1 is the most common parameters followed by 57600,n,8,1.
No handshake/flow control
(no hardware flow control, no software XON/XOFF flow control)
Should be your settings.
When I used Putty - I had to set those above parameters in 2 places
1) in the putty program settings itself
2) in the hardware port config options in device manager
In Linux - do you have to set it both in the hardware and
the software portion as well?

Re: WZR-HP-G300NH-R Fail
Every instruction I have seen only mentions setting up the USB/Serial in minicom, never in any other setting.
To connect the computer to the router I am using something like this: http://www.dealextreme.com/p/usb-to-rs2 ... reen-24512
It shows up in dmesg like this:
In lsusb it is:
I'm starting to get worried that this thing in borked. But the way it sends data looks like the router is working, its just not getting transferred correctly. Maybe my USB/Serial cable is borked? I might have an old router with a serial port on it that I might be able to look at.
Thanks for the help so far.

Re: WZR-HP-G300NH-R Fail
That could be the reason for the garbage. It looks like the adapter does not support TTL/3.3V.Statik wrote:Every instruction I have seen only mentions setting up the USB/Serial in minicom, never in any other setting.

Here is the exact adapter I have: http://www.dealextreme.com/p/usb-2-0-to ... cable-8757
I don't seem to have a female-female cable or adapter for DB9 so I haven't been able to test the adapter as yet. I'll see what I can locate.
Thanks!

The other one is USB to RS-232 which means its a standard serial port
Keep in mind - DO NOT mess with that 5v signal at all, you can fry parts
of your router and possibly your USB port if using wrong voltage levels.
You should only have to use the GND / RX / TX points of contact.

Re: WZR-HP-G300NH-R Fail
Ok, ordered. Now I have to wait until I can finally get this router working. *sigh* thanks for all your help...it'll be worth it in the end.

Re: WZR-HP-G300NH-R Fail
OK, so my USB adapter showed up today. I just plugged it in and booted the router. Here's what I saw. I'm going to go through it and try and follow the other links I have to upload a firmware. If you have any pointers, feel free to let me know!
Thanks!
