wifi dropping in Ubuntu 14.4
 

wifi keeps dropping in Ubuntu 14.4.This is odd because it didnt drop once in Ubuntu 13.10

What is your wireless chipset? (If you aren't sure, try running the command lspci in a terminal; that should display the information, unless you are using a USB adapter of some sort.)
