There's many reasons why your wifi could be running slow, but you will need to use Google and search for your wifi/routers make and model to find out how to change the settings. This is done by you and not your ISP. Also be sure your wifi access is locked down so that you don't have kids/neighbors downloading movies and leeching your bandwidth. That will definitely cause your speeds to slow down.
