I have a Dell Inspiron N5010, i5, 2.4, 4GB running win 7 home pre. I am currently using AT&T dsl with their Motorola modem. I am thinking I would like to be able to go wireless so I can move into the familyroom with computer and printer.

What wireless routers on the market today do you like, and what would be good for my needs? Buy new or used?

Thanks for any help you can give me.

What's your budget? If you can, go for one of the new AC routers.

I need to spend as little as possible.

What is an "AC" router?
.
E-bay has used Linksys wrt54g for $25.00 what are your thoughts on that?
Does it support the new lvP6. AT&T is going to lvP6 soon.

Thanks...
