Frontier ranks first for upload speed
While Spectrum takes the first spot for download speed, it ranks sixth for upload speed. Frontier claims the top upload speed with 151 Mbps, and AT&T ranks second at 139.79 Mbps.
Fast upload speeds will give you a better internet experience overall, but not all providers offer symmetrical upload and download speeds (e.g. 300 Mbps download, 300 upload Mbps). If you’re looking for a more seamless internet experience, fiber plans with symmetrical upload and download speeds will be your best bet.
