Need to test your office internet speed? The AT&T Business speed test measures both download and upload speeds, which are key to keeping video meetings, cloud apps, file sharing, and daily operations running smoothly. With our business internet speed test, you can see if your internet is fast enough to keep up with your day-to-day business needs.
We recommend running a business internet speed test under normal working conditions rather than during off-hours, when the network is quiet. A few simple steps can make your results much more accurate:
It affects cloud-based software, video streaming, large file downloads, webinars, and everyday browsing. For most businesses, download speeds of at least 100 Mbps provide a solid baseline, though companies with multiple employees or heavy cloud usage often need more.
Unlike home internet, upload speed is critical for video conferencing, cloud backups, sending large files, and sharing data with clients. A good upload speed for B2B companies is typically at least 20–50 Mbps, while businesses with frequent video calls or cloud workflows may require symmetrical fiber speeds.
Low latency is important for VoIP calls, video conferencing, and cloud collaboration tools that rely on real-time communication. Latency under 50 ms usually feels responsive, while latency above 100 ms can create noticeable lag, delays, and audio interruptions.
For reliable small business internet, most offices need at least 300 Mbps to handle email, web browsing, and video calls. Businesses with more employees, cloud-based tools, frequent video conferencing, or large file transfers typically need 500 Mbps or more. If your connection struggles during peak hours, it may be time to upgrade your plan.
A quick business internet speed test can help identify whether your current connection supports your workload or if additional bandwidth would improve productivity.

How do I test my AT&T Internet speed?
To test your actual internet speed, run the business internet speed test tool at the top of this page. All speeds are estimates. For best results, connect your computer to your business network via ethernet cable.
How can I boost my internet speed?
To boost your internet speed, make sure your hardware (modem and router) isn’t outdated, scan for viruses, and find your internet provider’s optimal settings. If all else fails, connect your device with an ethernet cable.
Which internet speed do I need for my business?
The amount of Mbps your business needs varies significantly depending on the number of devices connected and what they’re being used for. For a more clear idea of what internet speed is best for you, call and speak with an experienced AT&T Business agent.
What is a "good" upload speed for B2B companies?
A good upload speed for most B2B companies starts around 20–50 Mbps, especially for businesses that rely on video conferencing, cloud backups, file sharing, and online collaboration tools. Companies with remote teams, large file transfers, or heavy cloud usage may benefit from 100 Mbps or higher upload speeds. Because business operations depend on sending data just as much as receiving it, upload speed is a critical part of any business internet speed test.
Does my VPN affect my speed test results?
Yes, using a VPN can affect your speed test results. A VPN encrypts and reroutes your internet traffic through another server, which can reduce both upload and download speeds and increase latency. If you want the most accurate AT&T Business speed test results, test your connection once with the VPN on and once with it off. This helps determine whether slow performance is due to your internet connection or the VPN itself.
How often should I run a speed test for my office?
Most businesses should run a business internet speed test at least once a month and anytime employees report slow performance, dropped calls, or cloud application issues. It’s also helpful to test during peak business hours to see how your network performs under normal workloads. Regular testing makes it easier to identify recurring slowdowns, monitor trends over time, and determine whether your current internet speed for small business is still sufficient.
