If you are getting much lower cable, or DSL, or T1 modem speeds that you expected, it may be due to overloaded Internet feeds that may be shared among all subscribers in your immediate vicinity. This often happens in the evening when people are at home watching online TV movies and videos, which consume a ton of bandwidth. If the problem persists at various times of the day and night, there may be a loose or corroded phone or cable connection to your home.
