It gets the job done
Overall I’m happy with it. Some days are slower than others but I’m able to use it to stream tv shows and movies on my smart tv and I’m on my iPad all of the time using it so it does exactly what I need it to do. 😄

Best internet providers in San Diego, CA
Whether you’re streaming Max or teaching your grandma how to FaceTime, AT&T Fiber is one of the best internet providers in San Diego, California. The provider’s top-rated fiber service offers fast, symmetrical speeds that let you download a large movie file faster than it takes a Tesla to steal your parking spot in Mission Beach. Another great option is Spectrum, which offers a cable internet connection with speeds up to 1,000Mbps. In terms of speed and reliability, fiber providers should definitely be the first pick for any San Diegan, and cable providers second. However, college students and other folks on a budget can also try out T-Mobile 5G Home Internet, which is widely available, easy to install, and stays at a fixed price.
