is a TP-LINK router with a single antenna non-detachable antenna and a USB port. As of this moment, this is the smallest router available.
The package contains the router, a power supply, a USB-A to USB-micro cable.
|CPU||Atheros AR7240 @ 400 MHz|
|WAN or LAN||1x 100Mbps Auto MDI/MDIX|
|WiFi||802.11 b/g/n 150Mbps (130Mbps real) 20dBm - 100mW|
This router is standardly powered via USB at 5V. The voltage regulator inside is unknown, but its input voltage should be at least between 3.7V - 6V, possibly 8V. Maximum current draw at 5V is 185mA (OpenWrt boot), average current draw with WiFi at 18dBm is 100mA, without WiFi 80mA. Hence the average router power consumption is 0.5W, which is incredibly low.
Power consumption will be higher if a USB device is attached to its USB port!
Restoring to original firmware =
It is opened, by lifting the lid out with a screwdriver.
WAN port protected and isolated with transformer.
To power the router over PoE, R68 and R65 on the bottom side near ethernet connector have to be removed. Pins 7,8 of the ethernet connector have to be patched to GND and pins 4,5 to VCC (opposite pad to R113 mark)
Serial port is available on the board, on the edge opposite to ethernet connector, marked TP_IN - RX and TP_OUT - TX. Power can be harvested from somewhere on the board.
The router can be connected to the computer serial cable using a serial cable.
Connection can be established with the following settings on OS X or Linux:
cu --parity=none -s 115200 -l /dev/(your serial device)
There is already a USB connector.
The router can be upgraded/fixed with a TFTP method, although its use should be avoided if possible. A working serial cable is required.
- connect to the serial interface
- expect Autobooting in 1 seconds
write tpl within a second
- set ip of the router and computer (has to have a static IP)
setenv ipaddr 192.168.1.1 setenv serverip 192.168.1.100
- start tftp server on your computer and include the desired firmware in its path
- run the following commands
hornet> tftpboot 0x80000000 openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin hornet> erase 0x9f020000 +0x3c0000 hornet> cp.b 0x80000000 0x9f020000 0x3c0000 hornet> bootm 0x9f020000
- router will reboot and start with the new firmware
