1. Does this router support serial TTL console?
Yes: first read this: Serial Recovery
•
• Do not hook up your serial cable/wiring to the header used for the dome LEDs
• The serial connectors (JP1) are next to the dome LED header. Most production/refurb units will not
have a pin header mounted on the PCB for the serial connections (probably to save manufacturing
costs)
• The FCC photos of the internals show a header for both the dome LED and serial port
• Reference: OpenWRT WNDR3300 wiki
Reference thread for a photo with the pin outs: WNDR3300 serial pinouts
•
• The pin outs are as follows:
1. Pin 1 = 3.3V (towards the front of the router and should have "1" silk screened near the pin)
2. Pin 2 = RXD
3. Pin 3 = n/c
4. Pin 4 = n/c
5. Pin 5 = TXD
6. Pin 6 = GND (towards the rear of the PCB/back of router)
• JP1 = 3.3v TTL Serial, 115200/8/N, 1 row of six pins

Pin Short Recovery
(Not recommended) Short pins 16 & 17 while plugging in the power cable. Ping constantly with 'ping -t -w 1
192.168.1.1', and when you start to see TTL=100, remove the short and tftp a basic *.chk file to the router.
Give it a few mins to figure out what happened, and hopefully the WLAN lights should come back on. If
you're still pinging, things are good if you see a TTL=64, DD-WRT's signature.
Model and Revision Differences
• The WNDR3300v2 is actually a WNDR3400v1. Reference the FCC ID.
