Is their a way I could set up my wireless router from my computer?How do I set up a wireless router without being the host computer?
Well, A router does not use a ';HOST'; computer. It is a stand alone network device and there is no HOST for it!

So if you are authorized you can change it from ANY machine connected to it.



Most routers have a web interface at one of the following addresses.. just type them into your web browser to connect
