Answer 1

There is no need. You only need to have an Internet Service Provider, they furnish you with a Modem that allows you to connect via an ethernet cable.
You need 2 things to be wireless.
1st you need to have a wireless card in your computer.
2nd you need a Wireless Router that will then connect to your Internet Service Providers Modem to get wireless service.

Answer 3

There is no need to uninstall your wired Internet software, and it is a bad idea to do so. If you have a wireless router, and a wireless card in your machine, you can contrive to use that combination, and make it the preferred means of internet connection.
