TP-Link TL-WR743ND

WR743ND is a low cost (40€) b/g/n 150 Mb/s wireless router, capable of running OpenWrt.

Hardware is the same as TL-WR741ND with PoE capability on WAN port. Read the TL-WR741ND page for more informations.

Opening the case

It's the same procedure as for TP-Link WR741ND (see here for instructions)

Serial

To access the serial console of the wr743nd, you need
-1 solder a bridge like the two red points
-2 Connect a usb serial device (dku-5, ca-42) to Tx, Rx, Gnd.

Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

The above setup may not work (rendering serial console readonly). In that case, try soldering different bridge:
