TP-LINK TL-WR741ND
Wireless router with detachable antenna, upgradable with OpenWrt. Follow the instructions on the OpenWrt wiki. My model is V.4.x , purchased in Italy.
CPU | Atheros AR9330 |
---|---|
RAM | 32 Mb |
Flash | 4 Mb |
This is the recipe to install OpenWrt, I used trunk (BARRIER BREAKER, Bleeding Edge, r39638):
- Factory reset the router
- Download the *-factory.bin firmware image.
- Use the original web-based procedure to upgrade the firmware, upload the above image.
- Connect with telenet 192.168.1.1 and set the root password.
- Connect with ssh root@192.168.1.1

We installed the following extra packages:
- coreutils, coreutils-base64
- etherwake, wol
- kmod-tun, libbz2, liblzo, libpolarssl, openvpn-polarssl, zlib
- libpcap, tcpdump-mini
This is the free space after installing them:
