Digital Subscriber Line (DSL) is a type of Internet access that normally offers high connection speeds. However, various problems can cause DSL to slow down, especially when you make changes to your computer or telephone equipment. After determining why your DSL has slowed down, you may be able to correct the problem. Ask your Internet Service Provider (ISP) for help, or at least understand why you will have to accept a lower speed. Another possibility is that unfiltered telephone devices interfere with your computer’s connection to the DSL service. Verizon warns that missing filters can cause DSL connections to slow down (See Reference 3). DSL users should connect filters to every telephone and answering machine on the same line as the Internet connection. Perhaps you installed a new telephone without the necessary filter just before your DSL slowed down. Writer Bio
