it works like a cell phone. Usually a 3G network. Contact your local phone company, see what they offer, and see what is needed for the laptop. Usually a plug in card.
Easy. But don't expect blistering speed. It's better than dial-up but no where near cable speed. As mentioned above, it uses the cell phone data network, so expect connectivity issues unless you're under a cell phone tower.
I'm retiring my 8 year old HP Pavilion and am looking at a laptop and wireless internet. My current intenet provider is my cable company (no other alternatives). I travel to my parents house where dial up is the only way to access the internet. I have read a lot of the postings on this forum and I am a bit overwhelmed. There seems to be problems with connectivity and speed. Is wireless internet a viable option for someone not totally tech savvy?
