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 is to provide accurate and reliable data that forms the foundation of our recommendations for internet service providers (ISPs). We gather real-world data from millions of global users participating in Speedtest, offering authentic and current insights into ISP performance. Our goal is to deliver a transparent and unbiased evaluation of ISP capabilities.

Understanding an ISP's performance relies on evaluating three key metrics: download speed, upload speed, and latency. Download speed is crucial for tasks such as streaming and downloading, indicating how quickly data can be received. Upload speed is important for uploading content and online interactions, showing how fast data can be sent. Latency, or ping, is vital for real-time activities like online gaming and video calls, affecting how responsive a connection is. With a detailed understanding of these aspects, you can select an ISP that best matches your internet usage needs.

The underlying technology of an ISP greatly influences the quality of your online experience. Fiber optics generally offer the fastest speeds, ideal for bandwidth-intensive activities, whereas cable internet provides solid download speeds but may lag in uploads. DSL is adequate for basic browsing and streaming, and satellite internet, often the only choice in remote areas, tends to have higher latency and lower speeds.

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
  • Download huge files

1+ Gbps (Very fast)

  • Do anything you want on multiple devices

ISP Speeds in San Diego, CA

Our exclusive Speedtest data reveals Cox as the leader in San Diego for download speeds, achieving a median of 250.55 Mbps with their cable service.

As a basic guideline, having download speeds of 100 Mbps and upload speeds of 10 Mbps is generally sufficient for most online activities, such as streaming 4K HD content, downloading substantial files, or engaging in online gaming on several devices at once. The critical determinant of the needed speed for your home is likely the total number of devices connected to your network.

Home Internet in San Diego

San Diego, California, celebrated for its perfect climate, breathtaking beaches, and dynamic cultural landscape, blends natural splendor with city life seamlessly. Residents have access to diverse internet services like Fiber, IPBB, 5G, Cable, and Satellite, supporting a range of needs from simple browsing to sophisticated smart home management.

AT&T leads the market with extensive coverage, reaching 95% of city homes and delivering the fastest advertised speeds of up to 5,000 Mbps with its Fiber service. For those in less central areas, satellite options from Viasat, HughesNet, and Starlink provide reliable, albeit slower, internet access. Selecting the most suitable internet service provider involves evaluating service coverage, type of internet, and speed to match personal requirements and lifestyles.

However, it's important to note that there might be a gap between advertised speeds and actual internet performance, influenced by the chosen plan, network traffic, and local infrastructure. This gap underscores the necessity of selecting a provider known not just for high advertised speeds, but also for consistently reliable service delivery.
