My local library offers free wi-fi internet. I want to buy a netbook computer which has a built in wi-fi receiving modem. Is this all I need?
If two wi-fi signals cover the same area (eg the wi-fi range of the coffee shop outside overlaps into the library) will the computer give me a choice of which signal I want to use?
