Prolink PWH2004

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 (18.06 or later) 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 will end after 2019.
19.07 will be the last official build for 4/32 devices. After 19.07, no further OpenWrt images will be built for 4/32 devices. See OpenWrt on 4/32 devices what you can do now.

These units have 32M RAM, 8M flash, a serial port with pins marked on circuit board (CMOS level!), 4+1 LAN ports, 1xUSB port and 802.11n WLAN. The device is apparently also sold as Abocom WR5205.

Compiling firmware

Firmware can be compiled from “trunk”:

  1. choose Ralink RT288x/RT305x as target
  2. and RT305x boards as subtarget.
  3. Network interface needs boot option board=…. (WiP)
  4. For WLAN, include rt2800-pci module under Wireless drivers.

The USB port does not appear to work yet (2010/09/12).
