I had to move my modem from where the short cord AT&T provided would allow. I bought a 25 foot cable from Fry's Electronics but it never allowed my modem to reconnect to my ISP. I bought this 25ft cable from Revain and a few minutes after changing the cable I was back online. Speedtest.net showed my DL speed of 50.73 Mbit/s (I have a 40 Mbit/s plan), which means that I didn't lose any performance by changing cables. This cable looks cooler than AT&T's ugly green cable, and the RJ11 connectors look solid on both ends. Happy with my purchase.
