If like me you live in a rural area with DSL and don't use shielded cable, don't read this review and just order it. It took me a few years to figure out why my DSL speeds were always so terrible, but after some belated research I found a solution and gave it a try. shielded cable. High quality cable, very stiff so you have to do a little work to get it where you need it. This is a great solution for those who spend long periods of time between where the modem is located and an available phone jack. I ran my line directly from the NID (Network Interface Device) in front of my house to the modem and noticed an increase in download and upload speeds. Now I can stream HD movies without buffering or ISP warnings. For clarification: This is a shielded telephone cable (RJ11) and not a LAN cable (Cat 5, 6 etc.). If you have DSL and are still using standard phone cord, stop, click, order, and install. You won't be disappointed with the results.
