I feel your pain dude, I had WB, they told me nothing of a cap when I singed up, and every time I called it was bad weather(on a bright sunny day?!?!?!) if it was ok weather it was my router OR there was bad weather in Canada(WTF?!@?!?) and Canada was only after we unplugged our router.
Thankfully now I am on an un-caped WISP, and I love it.
