The easiest way to fix it is return it to Wal-mart and never, ever buy another Belkin.... You want a great wireless, buy an Engenius or even a few of the Linksys brand.
Sorry to say this, but Belkin is absolutely terrible.
Ummm. No, not that I know of. Honestly, it's not worth your wasted time when you consider the value of a new part. Unless either a) your time isn't worth anything to you or b) you love to tinker and the thrill of outsmarting the little devil. hehe.
