Right sorry if this is confusing. I have just a got a computer of someone which was a windows 2000 (millenium) because when i boot it up it says 2000 so im guessing it was but its now xp. I wasnt to connect it to the internet. I looked at the back and has no etherent cable input. I looked again and realised that there was no phone line either. I looked and looked and found where it was i got a scredriver poked through the plastic and found it but i really dont think it works. I was confused about these kind of things. I went to the computer shop and bought a wireless internet dongle to connect to the internet downstairs. I went to set it up and it doesnt work. I really dont understand why

Is it becase i have no modem , i really dont know. Could anyone help me and if needing more equipment to point me to it. Id be very greatful !
Thanks
