Eye-Fi Card SUCKS.... looking into wireless USB options. Can anyone help me out?

Hey!

Okay i'll get right to it... i saw someone on here mention a wireless USB option to have photos automatically upload to your computer, and i'm confused about the whole thing. So any help would be greatly appreciated!

I have a nikon D5100 with a Eye-Fi x2 8gb card. I'm having SO MANY problems with the eye-fi card that i'm just about ready to break something. Some of the problems:
-Card takes 10-20 minutes to start uploading pictures
-Card never uploads
-Pictures show up half gray sometimes, rendering them useless

-when i insert the eye-fi card into my computer, it freezes. last time it basically jumbled all the images and their names into files like D.2XXp%-6.JhZ, and i had to reformat the card.
-sometimes all my new photos disappear and the card is empty.

I'm done with it. At this point i can't even take pictures and insert the card into my computer and copy them manually.

So i've been looking up wireless USB and i'm confused about it a little. Do i need a wireless USB device for the camera AND for my computer? On the D5100, it has a mini-USB port. Do they make mini-usb wireless adapters? Can anyone suggest a device or product that would work for my camera?

Any help would ge greatly appreciated!
