Airlink101 AR670W

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.
DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details.

1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.
This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.

2) OpenWrt support for this device has ended in 2022.
19.07.10 was the last official build for 4/32 devices.

Install OpenWrt (generic explanation)

The stock firmware has a recovery mode triggered by holding down the reset button on power-up or hitting escape at the serial console. The recovery interface is accessible via HTTP at The OpenWrt factory image is compatible.

When connected to the serial console, it is possible to drop into a u-boot prompt by hitting 'q' in recovery mode. Note that there is no saved u-boot environment on flash, so you will have to set e.g. serverip every time you need to use TFTP.

The SoC's builtin Ethernet is connected to a IP175C 5-port 100mbit switch. VLAN setup is supported in OpenWRT.

The serial port is located at JP2 on the board. The baud rate is 57600.
