Both AT&T Internet and Xfinity offer fiber-optic service, the fastest connection type and wired internet’s “gold standard.” If you live in a large household with power internet users who connect to the internet on multiple devices, then you’ll want a fiber internet plan to fulfill everyone’s needs. AT&T Internet download speeds reach up to 5 Gbps, making it one of the fastest fiber internet providers. Xfinity offers download speeds up to 3 Gbps, so it’s not far behind.
If you don’t need lightning-fast speeds, then you can opt for either provider’s alternative connection offerings. AT&T Internet plans include fixed wireless and internet protocol broadband (IPBB), whereas Xfinity plans and bundles primarily operate on cable. AT&T Internet’s lowest-priced non-fiber plan is $55 per month, while Xfinty’s lowest-priced non-fiber plan is $39.99 per month. An ISP’s cheapest plan, however, doesn’t always give you the best download speeds.
