How to setup a wireless router? Say I have about 10 pcs.

This medium is best suited for asking and getting answers to specific questions, not a general tutorial.

Have you read the manual for the router? What specific questions do you have about setup?

Generally you connect the router to your broadband modem and power it up. You configure the router using a wired connection. Then power up the wireless PCs and they should find the router and make the connection.

I agree with Scott. Whatever router you purchase will come with all the documentation you should need. Try it first then come back here if you have any questions.

What are you disagreeing with? You didn't ask a question and there was nothing incorrect with my answer.
