Topic: wrt300n V1 serial port and wireless driver
I hope I can help out a few people with the information that I found over the last day or two...
Running Kamakazi 7.09...
I messed up my wrt300n to the point where I couldn't ping it, etc. It appeared to boot, flashing power led for a bit, once booted the LED was solid on. Don't know if this assumption is 100%, but I went with it anyways.
So I decided to open the case an probe around.
Here's what I found for the serial port:
Connector JP2, which is located behind the WAN (blue) port.
Pinout as follows (left to right):
GND ??? RXD TXD VCC (I'm assuming that the ??? is the flow-control pin from the router).
You'll need a level-shifter (MAX232 or equiv) to connect to a standard serial port.
Settings: 115200 8-n-1
Turns out I messed up the config/network file and the lan driver didn't initialize. Easy enough to fix as it booted into the shell.
I set off to figure out how to start up the wireless side.
Looking through the wiki, I found that the Asus WL-500W has the same wireless chipset. (http://wiki.openwrt.org/OpenWrtDocs/Hardware/Asus/WL500W)
So I decided to follow the docs and see what happens. I left the network settings alone and created the config/wireless file.
I then updated and installed the wireless mimo driver:
ipkg install kmod-brcm-wl-mimo
And Viola! I have a wireless AP once again (limited to 54Mbps, of course).
