Not all plans are available in all areas. Provider plan, availability, and speed tier data provided by BroadbandNow.com. Speedtest real-world data is only present where sample size has reached significance within a region. Additionally, averages may include aggregated tests across multiple Internet Types (Fiber, DSL, Cable, etc.).

At Speedtest, our commitment lies in providing accurate and trust-worthy data that serves as the cornerstone of our ISP recommendations. Our comprehensive insights are derived from the extensive collection of real-world data sourced from millions of Speedtest users across the globe. This robust dataset ensures our analyses of ISP performance are reliable and up-to-date, offering a transparent, unbiased perspective on ISP capabilities.

Evaluating an ISP involves considering three pivotal metrics — download speed, upload speed, and latency. These metrics are essential for various online activities; for example, download speed is crucial for streaming videos, upload speed is important for sending files, and latency is key for online gaming. Understanding these aspects can guide you to make informed decisions about your internet service based on your specific needs.

Various internet technologies, including fiber optics, cable, DSL, and satellite, play significant roles in dictating the quality of your internet experience. Fiber optics are generally expected to deliver the fastest speeds, making them ideal for heavy internet usage, while cable and DSL provide dependable speeds for everyday online activities. Satellite internet, typically used in remote areas, might offer slower speeds and higher latency.

How Much Speed Do I Need?

Download speeds of at least 100 Mbps and upload speeds of at least 10 Mbps are widely considered fast enough to handle nearly any online activity. A quick guide to what speeds you need for different online activities is below, and you can read our full guide to internet speeds and performance for more information. Keep in mind that the numbers below are the bare minimum for one device at a time. If you’re trying to use multiple devices on a network at the same time, you’ll want higher speeds.

0–5 Mbps (Slow)

  • Stream SD video
  • Connect on Slack
  • Use Microsoft Teams
  • Write and read email
  • Scroll social media
  • General web browsing

5–20 Mbps (Better)

  • Stream HD video at 1080p

20–40 Mbps (Solid)

  • Stream 4K video
  • Play games online

40–100 Mbps (Good)

  • Stream HD games

100+ Mbps (Fast)

  • Engage in multi-player gaming

  • Do anything you want on multiple devices

ISP Speeds in Ontario, CA

In Ontario, California, our proprietary real-world Speedtest data based on thousands of user speed tests has identified Spectrum as the ISP boasting the fastest recorded median download speeds at 322 Mbps. This impressive speed highlights Spectrum's robust network capabilities and up-to-date infrastructure, particularly for consumers in need of high-speed internet for streaming, gaming, and other bandwidth-intensive activities.

Regarding advertised maximum download speeds, EarthLink Fiber takes the lead with an astonishing maximum advertised speed topping out at 5 Gbps. It's important to note, however, that there may be a discrepancy between these advertised speeds and the actual speeds users experience, a common phenomenon across ISPs. Other providers like Onward and Spectrum also advertise gigabit speeds of up to 1 Gbps, appealing to customers looking for high-speed fiber options.

A good rule of thumb to remember when choosing the right ISP and plan for your needs is that download speeds of at least 100 Mbps and upload speeds of 10 Mbps are generally considered fast enough to handle nearly all types of internet usage. With 100 Mbps, multiple devices can stream 4K HD videos, download large work files, or play HD games without noticeable lag. Considering your network usage and the number of people and devices that will use the connection is crucial in determining the speed you need. Internet usage is cumulative, meaning the overall network speed requirement increases with each device added to your home network. Just a few connected devices? You can get away comfortably with a lower cost and lower speed plan, but the more you add, like smart fridges or ovens, the more you'll need to think about upping your plan to higher bandwidth speeds.
