Everything you need to know about internet speeds in 2026

A megabit per second (Mbps) is a unit of data transfer speed — specifically, a million bits moving each second. A gigabit per second (Gbps) is a thousand times larger: 1,000 Mbps. Providers advertise plans using these numbers because they describe the maximum rate your connection can move data, not how much data you're allowed to use in a month (that's a separate thing called a data cap, covered in our data caps guide).

Bigger isn't always necessary. A single 4K stream uses roughly 15 to 25 Mbps; a video call uses a few Mbps. The jump from 100 Mbps to 1,000 Mbps rarely changes how either of those feels — it mostly matters when many things are happening simultaneously, which is why plan sizing is about your household, not any single activity.

Download speed is how fast data moves from the internet to you — streaming a show, loading a webpage, downloading a file. Upload speed is the reverse: sending a video call's picture and sound out, uploading photos to the cloud, or sharing a large file.

Most home internet plans, especially cable, are asymmetrical: download speed is much higher than upload. That's fine for a household that mostly watches and browses, but it can bottleneck anyone who works from home with frequent video calls, livestreams, or large uploads. Fiber plans often offer symmetrical speeds, where upload matches download — see our fiber vs. cable comparison for more on this difference.

When comparing plans, look at both numbers. A plan advertised by its download speed alone can hide a surprisingly slow upload speed.

Latency is the time it takes for a signal to travel from your device to a server and back, usually measured in milliseconds and sometimes labeled "ping" on a speed test. It matters most for anything real-time: video calls, online gaming, and voice assistants. A connection can have excellent download and upload speeds and still feel laggy if latency is high or inconsistent.

Wired fiber and cable connections typically have low, stable latency. Satellite internet, because signals travel to and from orbit, has structurally higher latency that no amount of download speed fixes. If a real-time activity feels sluggish despite a fast plan, latency — not speed — is usually the cause.

These are general, commonly cited figures per device or activity, useful for estimating — actual numbers vary by service and video quality.

A speed test only tells you about the exact path it measured, so how you run it matters. For the most accurate read of what your plan actually delivers, connect a computer directly to your router or gateway with an Ethernet cable and run the test — this removes Wi-Fi from the equation.

Run a separate test over Wi-Fi, in the rooms you actually use, to see what your household is really getting day to day. If the wired result is close to your plan's advertised speed but the Wi-Fi result is much lower, the gap is coming from your home network, not your provider — see our modem vs. router guide for how to diagnose and improve that.

Test at a few different times of day, since shared networks can dip during evening peak hours; see our guide on why internet slows down at night if you notice a pattern.

Advertised speeds describe the maximum your wired connection can carry — they're a ceiling, not a promise for every device in your home. Wi-Fi reduces that ceiling for several ordinary reasons: distance from the router, walls and floors in the way, interference from neighboring networks, the number of devices sharing the connection at once, and the age of the device itself, since older phones and laptops often can't use newer, faster Wi-Fi standards even when your router supports them.

None of this means you're being shortchanged — it's simply how wireless networking works. Placing your router centrally and off the floor, upgrading an aging router, or adding a mesh system for a larger home are the practical ways to close the gap between what you're paying for and what you actually feel.

Start with how many people in your home are regularly online at the same time, and what they're doing. A household of one or two people who stream and browse can be comfortable around 100 to 200 Mbps. A busier household with several devices, video calls, gaming, and streaming at once is often better matched to 300 to 500 Mbps. Multi-gigabit plans mostly benefit households with many simultaneous heavy users, frequent large uploads, or a strong preference for future headroom.

Whatever you land on, treat the advertised number as a starting point and double-check upload speed and typical latency for the exact plan you're considering — those two details usually explain more about how a plan will feel than the headline download figure.
