Carlos has Spectrum broadband and it starts fast but then slows down gradually to a stop. Leo says that Spectrum has a "burst mode," which is designed to fool speed tests to make you think you're getting faster service than you are actually paying for. But it shouldn't slow down to a stop. Carlos has said that they have rewired the house, checked outside, and they can't track it down. Leo says it could be a bad splice at the junction box. You can also try a new router. Really the only choice is to change providers.
Jeff bought an Senior 55 unlimited plan from T-Mobile, but his data plan is extremely slow. Leo says it's likely unlimited because you get 3G data access, not 4G/LTE. But he's not getting hotspot mode, because it constantly disconnects. Leo says that hotspotting with your laptop is never going to be as good as direct connection. Your phone's connection may go to sleep, dropping the hotspot.
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!
Steve wants to know if the rated speed the ISP says he's getting is legit. Leo says it's ideal and it's subject to a lot of factors. Broadband often has shared bandwidth, so if everyone is watching Netflix, it's going to slow down. It's also dependent on wireless congestion. Wired is always faster. It can depend on the quality of wiring, the age of the router, and more. It's very complicated. It can even be his computer that's slowing his internet speed down, and one will be faster than another.
