Wireless Internet in Linux Mint
I am a new user in the linux system. I have decided to go with Linux Mint since i was told it was the best for beginners to start with. At home i use two different wireless hubs both by BT as they are my ISP. I am hoping to install Linux mint on a dead PC that had XP previously before made redundant with viruses. i am planning to buy a wireless adapter off ebay, which i hope to use to connect wirelessly to the internet from my new Linux Mint system. I was wondering do i need to be careful about the adapter i buy like i would have to be buying a modem and can i still use my two wireless hubs variably as i wish as long as i install both on the linux mint? and if i do how do i actually go about installing a wireless connction on my linux?
Advice would be most helpful.
