For those of you who aren't familar with DD-WRT, it can replace your home router firmware and provide much more control and additional features not normally available.
Some people I have spoken to dismiss it as a software hack for recreational use, but I have been using DD-WRT for work and find it very helpful for some jobs. I use it in my lab, in the field, my wireless class, in my office and for some consulting engagments.
For example, some of the wireless features are;
- create multiple SSID's with different authentication settings
- configure each SSID with diffent QOS settings
- monitor clients' radio stats (RSSI, NOISE, etc)
- create a bridge, WDS or use the router as a client
- can perform site survey to record what SSID's it can hear
Some other features;
- I can monitor usage, number of TCP and UDP connections
- can use Radius to Authenticate
- QOS support
- NTOP Statistics
- VPN (Open, PPTP) client and server (with vpn version)
- SSH Server and Client
- Telnet server
and many other features. In this tutorial, I show you how to get started by installing DD-WRT on a Linksys WRT54G home router. Then I briefly show you some of the wireless features within DD-WRT.
