At the web sites of the five largest cable operators, upload speeds almost never get the same billing as download speeds; at worst, you may need to look up a technical-support document. Comcast, the nation’s largest internet provider with 27.8 million residential broadband customers, doesn’t list upload speeds if you check for its Xfinity service at an address or start ordering service at its site. Spectrum, the second-largest provider, also doesn’t list upload speeds if you check for or order service.
