Jeff has DSL and lately it's been really slow. Leo says that outside, about 2 miles from the hub, DSL is just unusable, which is why cable is a better option. The cable company tech added an "attenuator" on his line, which is designed to protect devices if the cable has too much of a signal. It doesn't affect speeds, it just protects electronics. Just leave it on, especially with 400 MBps!
A TV converter box is the set top box that comes with a cable subscription, and it takes the signal coming in through the copper cable and turns it into something the TV can understand. He would use the converter box to switch channels. The internet box is a bit different, and would give him the cable internet access. Often times companies will combine the two and offer a converter box and a cable modem. He would get more channels on the hybrid cable TV and internet box, but he'd have to pay for the internet access to use that.
Jane had DSLExtreme and she recently lost access to it. She says that DSLExtreme wants to come into her home and install fiber. Is that a good idea? Leo says it will be a bit more expensive. One possibility is that AT&T may be up to something. THey could be cutting the copper in your neighborhood, which is a bad business practice. AT&T is cutting the copper in your neighborhood and trying to get you to sign up for uVerse, which uses fiber optics. It's just like cable, only faster.
