PLEASE HELP with wifi question?

The name of your network (which is what you mean when you say "router") is called an SSID - Service Set IDentification. - it's given a default name by the manufacturer (you can't change the name of the router since that is the manufacturer's name). There is no strong reason to change it, although some argue that leaving it as the default makes it easier for those who know equipment to figure out how to hack it since the default name gives away the manufacturer, and therefore the default passwords, which can then be used to access your network - unless you change them, which is highly recommended. But if you think changing the name is more important, you can:

Go to the setup/configuration pages. The URL for this should be on a label on the back/under side of the router but for many routers is http://192.168.1.1/ or http://192.168.0.1/ or http://www.routerlogin.net/ or http://www.routerlogin.com,/ so try these in a browser address line, and one of them should get to a login dialogue box asking for username/password. The default for many routers is admin/password, or admin/1234, or admin/_________ (blank) - you'll have to find the one for your make/model since you didn't provide that information.

Once logged in you'll look at the various pages to find the SSID. Simply change it there - and I suggest you write down the new name since it is no longer the default name.

I more strongly suggest you ensure that you are using security measures - WPA2 is considered the strongest currently, and change the default password for this and write it down. This is really your best protection against poaching, since anyone with the proper gear, software and knowledge can "sniff" your signal and hack it regardless of the SSID name, but WPA2 is much more complicated. Anything is hackable, but why make it easy?
