i just set up a wireless router for wifi in my house this week.
i was nervous about it but the software wizard took me through the whole thing stepby step.
like:
first disconnect your modem from the power supply
(then the software checked on this)
now connect the router to the modem using the blue lan cable provided. plug it int the router in the outlet called internet 1
(then the software checks on stuff)
now connect etc
then it asked me some questions like what kind of security do i want to set up and it explained the choices, what password for the wifi, what password for the router, etc.
then it recorded all the passwords and names in a text file that it put on my desktop.
the whole thing was painless, about 15 min
i used d-link brand, no reason, my kids bought it for me.
i imagine other brands are also helpful.
