How can I get Internet access at home without having a landline phone for dsl or cable?

There are wireless compaines that will supply you service such as verizon wireless or others that are unique to your location. These compaines are often capable of providing DSL performance without the need for a phone line. Second option is to obtain an omnidirectional antenna and hook it up to a linksys wireless-G PCI card through a pigtail and you will be able to leech off of your neighbors for miles away, depending on geographics. Legit or not legit your call, but both work.

You can still use a wireless card like a laptop from sprint, cingular,etc. in your desktop

Some cell phones can be used as a modem.I have an iDEN motorola i850 with nextel that works. "iDEN USB Installation Application/USB Modem Driver This software applet will install all necessary iDEN USB files and drivers for use with your iDEN USB cable. This will also automatically create a USB Modem for compatible Windows based computers."

AT&T offers a NO phone line DSL service. When you call you have to ask them to transfer you to the DSL with no dial tone line because you go to the main channel and get routed from there. Don't call on a Monday or after 7pm...longer holds.

A few phone companies will do DSL without land-line telephone, and that may be your best bet: the only other alternative is satellite, which is expensive ($50 a month), and at the moment not available because the satellite company is debugging a new bird.
