Internet plans are sold by the number, but the numbers are easy to misunderstand. Download speed, upload speed, latency and link speed all affect how fast your business feels, and the cheapest way to fix slow internet is often not a faster plan.
This guide explains what the numbers mean, how much speed a business really needs, how to test your connection and what to do when it is slow.
- Mbps and Gbps measure bandwidth; latency measures delay.
- Upload speed matters as much as download for cloud work, video and cameras.
- Test from a wired computer to separate Wi-Fi problems from internet problems.
- Dedicated, symmetrical service performs consistently; shared plans slow down at busy times.
The Numbers, Explained
| Term | What it means | Why it matters |
|---|---|---|
| Mbps / Gbps | Megabits or gigabits per second (1 Gbps = 1,000 Mbps) | How much data can move at once |
| Download | Data coming in | Websites, cloud apps, streaming |
| Upload | Data going out | Video calls, backups, cameras, file sharing |
| Latency (ping) | Delay in milliseconds | Voice, video and real-time apps |
| Jitter | Variation in latency | Choppy calls and frozen video |
Note the difference between bits and bytes: a 1 Gbps connection moves about 125 megabytes per second, which is why a file download shows a smaller number than your plan speed.
How Much Speed Does a Business Need?
Start with the busiest hour of the day, not the average. Count people on video calls, cloud apps in use, cameras uploading, and guest Wi-Fi.
| Business | Typical need |
|---|---|
| Small office, 1 to 10 people | 100 to 300 Mbps |
| Office of 10 to 50 people | 300 Mbps to 1 Gbps |
| Heavy cloud, video or cameras | 1 Gbps and up |
| Venues and events | Sized to attendance |
Why Upload Speed Matters
Many broadband plans offer fast downloads but uploads at a tenth of that speed. That was fine when businesses mostly browsed the web. Today, video meetings, cloud backups, file sharing and security cameras all send data out, so a slow upload becomes the bottleneck. Symmetrical service, with equal upload and download speeds, removes it.
How to Test Your Speed Correctly
- Use a computer plugged in with an Ethernet cable, not Wi-Fi.
- Close other apps and pause backups during the test.
- Run several tests at different times, including your busiest hour.
- Compare download, upload and latency to what your plan promises.
- If wired results are good but Wi-Fi is slow, the problem is your Wi-Fi.
Common Causes of Slow Internet
- Wi-Fi coverage: distance, walls and old access points.
- Old cables or switches limiting your local network to 100 Mbps.
- A shared plan that slows down when the neighborhood is busy.
- Too little upload for video calls and cameras.
- An outdated router that cannot keep up with the plan.

Speed Needs by Activity
| Activity | Approximate bandwidth per user |
|---|---|
| Email and web browsing | 1 to 5 Mbps |
| HD video call | 3 to 5 Mbps up and down |
| 4K video streaming | 15 to 25 Mbps |
| Cloud backup or large uploads | As much upload as available |
| HD security camera (cloud recording) | 2 to 6 Mbps upload each |
Multiply by the number of people doing each activity at your busiest time, then add headroom for growth and guest Wi-Fi. A business that seems fine at 9 a.m. can stall at noon when everyone joins video calls.
Shared vs Dedicated Bandwidth
Shared broadband divides a neighborhood’s capacity among many customers, which is why speeds drop in the evening or during busy hours. Dedicated internet reserves capacity for one business and backs it with a service level agreement. If your speed tests vary widely by time of day, a shared plan is the likely cause.
Getting Consistent, Guaranteed Speed
If your tests show the plan itself is the limit, dedicated business internet solves it with guaranteed, symmetrical bandwidth and a written SLA. Cronus delivers dedicated fiber and fixed wireless in Detroit with speeds from 50 Mbps to multi-gigabit.

Frequently Asked Questions
What is a good internet speed for a business?
Most small offices do well with 100 to 300 Mbps of dedicated, symmetrical bandwidth. Larger offices or those with heavy cloud and video use often need 1 Gbps or more.
What is the difference between Mbps and MBps?
Mbps is megabits per second, used for internet plans. MBps is megabytes per second, used for file sizes. One megabyte equals eight megabits.
Why is my internet slower than my plan?
Common causes include Wi-Fi coverage, old cables or switches, a shared plan at busy times, or a router that cannot keep up. Test from a wired computer to narrow it down.
What latency is good for business?
Under about 30 milliseconds is good for voice and video calls. Consistency matters as much as the number.
