I notice that this was posted quite awhile ago, but I didn't know if you'd found any help in your area other than satellite.
We live 30 miles east of Kansas City, and we only have satellite providers as well.
However, we did purchase the AT&T (shown as the Cingular on this info.) and it works well.
If you have cell phone service in your area, that provider should have something that works....but may only be on a laptop.
My desktop did not have a slot to accept the original wireless card, however they now make them as a USB connection which should work on a desktop.
Our satellite service, Wildblue is horrible, very expensive and the only advantage is our phone line is no longer busy.
I am in the process of researching further ATT products to use on the laptop we got to replace our desktop, that's how I ended up seeing your post.
Call your cell phone provider and they should have something now...I can't wait to cancel my Wildblue/Gotsky service!
