Tp-link tl-wr841n dd-wrt
The Barrier Breaker image already includes a GUI, you do not have to install it manually.. Note: Newest version of tp link firmware (tested on TL-WR841N_V9_150310 / 3.16.9) does not accept openwrt firmware filename, because they are too long ; rename it to something < 64 chars, ending with .bin.
