Programmatically changing wireless router settings

问题:

Is it possible to programmatically change settings on a Netgear wireless router using C#? I have settings that I change often and I would like to create my own interface for making those changes. Currently I navigate to the admin web page (10.0.0.1) and it prompts me for a username and password. After I authenticate I can use the web interface to change the router's configuration.

If this isn't possible with Netgear, do any outher wireless routers have an API for developers?

回答1:

There aren't any APIs out there to do this, but you can write something to make HTTP requests to the router to simulate the webUI being used.

I'm guessing most consumer routers are probably pretty simple to talk to. Authentication is probably nothing more than basic realm.

Selenium offers a firefox plugin that lets you record manual interactions with your browser. And then you can export the steps to python, ruby, java or c#. It worked for me to programmatically adjust my router settings to turn off wifi. Clicking on the elements while recording identifies everything you need.

This code works on an Actiontec MI424WR (FIOS)
Edit the code to add your username, password, and router address.

I'm unaware of any consumer-grade routers that have an API like that, but you could always build something that (ab)uses the Web interface to do what you want, using something like selenium-rc or watir

回答4:

MiktoTik sells customer grade routers that allow ssh configuration (mind that they use ssh, but not bash inside ssh). You can even roll your own PHP REST API for router (not that I like PHP, but people are doing it).

回答5:

If this is just a few things you want to change programmatically, simulating HTTP requests should be simple enough. Another option would be to install DD-WRT in your router, basically transforming it into a small Linux installation that allows full programmatic configuration through SSH using standard Linux commands.

I'm not familiar with this router, but I have done similar stuff programmatically via a telnet connection the router with Python. There's a cood telnet lib for C#: http://www.codeproject.com/KB/IP/MinimalisticTelnet.aspx
