Prolink PWH2004

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 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.

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.
