Xfinity's TECHNOLOGY

Comcast broadband services are mostly "cable", meaning they share the wiring that sends TV through the coax jack.

Cable companies use coaxial copper wires. Cable lines can handle much more bandwidth than DSL service. However, cable has lower speed than fiber Internet service. Cable providers like Xfinity usually have higher download speeds than upload speeds.

Comcast has upgraded to gig download speeds in select areas as of 2018, thanks to DOCSIS 3.1.

Sonic's TECHNOLOGY

Sonic.net offers broadband Internet, TV, and phone services using both DSL networks. Sonic also offers Fiber in some areas.

Their DSL offerings come in two technical flavors —VDSL or ADSL2. In practice, DSL broadband provided via phone lines. Although DSL cables are poorer performers than cable, phone wires are connected directly to residences instead of sharing between neighbors, making Sonic service more reliable during peak use times. [2]

Sonic’s fiber offerings provide FTTH (Fiber to the Home) infrastructure, the best consumer broadband option available to consumers. Because it's expensive to install fiber lines all the way to a subscriber’s building, Fiber to the Home service is less commonly available compared with Sonic DSL network.

Xfinity INSTALLATION

Xfinity self-installation is the quickest choice for most subscribers.

Professional installs come with a small charge. For customers ordering TV services, scheduling a professional installation is best, as the wiring is more complex.

Sonic INSTALLATION

Sonic.net customers have two options: self-installation (free), and scheduling a professional installation, which comes with a nominal fee.

Self-installation isn't complex. Detailed instructions will come with the kit. Essential equipment including the modem unit and gateway will come with the kit as well.

Professional install is best for subscribers who would prefer not to deal with installing and configuring their equipment.

What’s in the contract?

Keep an eye out for extra fees in your monthly bill

Monthly bills have a tendency to creep up, and it’s not always because the provider is pulling anything fishy — broadband technology is constantly evolving, and the price often reflects advances in technology and quality of service. That said, extra fees can sometimes be added to your monthly bill in error, and if you find unexpected line items, don’t be afraid to call up your provider and ask for an explanation.

Additionally, ETFs (early termination fees) sometimes apply to service contracts, and should be considered carefully by anybody who anticipates moving or switching providers. A high ETF can quickly eat up any savings from bundling services or signing a multi-year agreement if you wind up having to relocate before it ends.

Quality of service

How to know if you can trust a provider

Customer reviews online are notoriously difficult to trust. When it comes to broadband providers like Xfinity and Sonic.net, there are two sources you can trust: ACSI ratings and IP-verified customer ratings.

ACSI (the American Customer Satisfaction Index) ratings are particularly trustworthy, since the data is based on surveys manually administered by trained experts. ACSI is the nationwide “gold standard” for assessing quality of service.[1]

In addition to ACSI ratings, you’ll see IP-verified customer ratings on BroadbandNow. These ratings are based on actual visitors to BroadbandNow, using IP-verification technology to ensure that the person leaving a review is actually using the provider in question. Providers with higher customer satisfaction ratings may be worth choosing even if their prices are higher, since you know they’ll be more dependable to quickly fix outages and other issues.
