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 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.

Usb, wifi, lan, all seem to work. This device is very similar to Dovado 3GN, Same board, cpu. !! WARNING !! Since trunk rev 33300, all lan ports including wan port acts as a dumb switch. There is no NAT. This is not yet fixed and it is related to swich functionality which was added from rev 33300. Everything is working good up to rev. 33298. So remember to compile your own working image. The bug might be fixed in r34379 as claimed in 12125. A working (but maybe older) firmware from this thread. This is an outdated howto.
