Dynalink RTA1025W

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.

1. Update the CFE (bootloader) and image format by flashing a new stock firmware

Flash this firmware Dynalink RTA1025W / NetComm NB6PLUS4W In firmware 3.64y the CFE will be “Boot Loader, Version 1.0.37-6.8.5”

Or try some of these if there is any newer CFE in them Stream-TST Firmware Files Forum page (not tested by myself at time of writing)

2. Flash the OpenWRT image - use any preffered method

3. On first boot enter 'mtd fixtrx linux' command in the OpenWRT console without this - the CFE will not boot and will wait for flashing a new firmare

This is all the useful information for this example configuration. The Ethernet frames are bridged by OpenWRT from the Wi-Fi AP to VLAN 15 on the LAN side.


FIXME The picture is in contradiction to the pinout described below. If you know the correct pinout, please correct it.

Serial connector (white, look at the pictures)
| 1 | -> Rx
| 2 | -> Tx
| 3 | -> GND
|_4_| -> +3,3V
