4G Internet

I have 4G Internet from Clear.com. I had a problem with the on off button so I removed the program. ( I thought I removed the clear progam)
It wont let me install it. Clear.com thinks I am missing the
wireless driver. The Device manager under other devices shows
a problem with Intel(R) Centrino(R) Wireless-N + WIMAX6150

Do have sugestions on how to reinstall my wireless device so I can
reinstall the Clear program.

Thank you
