Based on the offers in this comparison, Quantum Fiber and Xfinity have similar pricing at some speed tiers.
Quantum Fiber Pricing
Quantum Fiber’s advertised 1 Gig promotional offer is $45 per month.
A 2 Gig plan is also available in select areas.
Xfinity Pricing

| Xfinity Plan | Monthly Price |

| 500 Mbps | $45 |
| 1 Gig | $50 |

However, availability and promotional pricing can vary by location.
Quantum Fiber vs Xfinity: Speed and Performance
Network technology is one of the biggest differences between these providers.
Quantum Fiber
Quantum Fiber uses a 100% fiber-optic network.
On applicable plans, it offers symmetrical upload and download speeds.
For example, a 1 Gig fiber plan can provide up to gigabit-level upload and download speeds where the plan supports symmetrical service.
This can be particularly useful for:
- Remote workers
- YouTubers and content creators
- Gamers
- Video editors
- People who upload large files
- Households with heavy upload requirements
Uploading a large video, backing up files to the cloud, or participating in video calls can benefit from stronger upload performance.
Xfinity
Xfinity’s network is also fiber-powered, but the connection to the premises can use coaxial cable.
This is different from a full fiber-to-the-home connection.
Xfinity can still provide fast download speeds, including gigabit-level service, but upload performance can differ from a symmetrical fiber connection.
If you mostly browse websites, stream video, use social media, and download files, download speed may be the more important factor.
If you regularly upload large files, the difference becomes more noticeable.
Quantum Fiber vs Xfinity: WiFi Equipment
Quantum Fiber offers WiFi 7 through 360 WiFi with applicable service.
Xfinity also includes WiFi equipment with the plans described here.
This means you don’t necessarily need to purchase a separate router immediately after signing up with either provider.
The actual WiFi performance in your home will still depend on factors such as the equipment, home layout, walls, interference, connected devices, and placement.
Your internet plan speed and your WiFi speed are also not always the same thing.
Quantum Fiber vs Xfinity: Data and Contracts
Both providers offer unlimited data on the plans covered in this comparison.
Neither requires an annual contract for these offers.
This means you don’t have to choose between a cheaper contract plan and a more expensive month-to-month option.
However, you should still review the terms of the specific offer you’re signing up for, particularly if it includes promotional pricing or additional benefits.
Xfinity’s Price Guarantee and Perks
One of Xfinity’s major selling points is its 5-Year Price Guarantee on applicable advertised offers.
This can make monthly budgeting easier if the offer you qualify for includes the guarantee.
Xfinity also has additional services that can add value depending on what you already use.
Eligible offers may include:
- Xfinity Mobile promotions
- A free Xfinity Mobile line for one year
- Peacock Premium on select plans
- Included WiFi equipment
These benefits can make the total value different from simply comparing the internet price.
Quantum Fiber’s Additional Benefits
Quantum Fiber doesn’t require you to bundle other services to get its internet service.
Eligible customers can also receive up to $480 per year in AT&T Wireless savings under applicable offers.
The exact savings and eligibility requirements should be checked before signing up.
If you already use eligible AT&T Wireless service, this benefit could affect the overall cost of your internet and mobile services.
