Why Is My Wi-Fi Not as Fast as Advertised?

A Wi-Fi router sitting on a home office desk next to a computer and notebooks.

So the advertising in your Wi-Fi router guarantees a sure velocity however your expertise with the router doesn’t stay as much as that velocity. What provides? Right here’s why you’re not getting the marketed expertise.

Earlier than we leap into speaking about why your router’s velocity is lower than what the field marketed, let’s slender down the scope of this text instantly.

We’re ranging from the place that your web connection is functioning as anticipated (velocity assessments look good, your Wi-Fi sign is robust, and also you’ve used these tricks to optimize your Wi-Fi) however you’re not getting the velocity you anticipate primarily based in your router’s specs.

The Router’s Marketed Velocity Is Theoretical

The speeds marketed on the field and within the documentation for a specific router are the theoretical most velocity the router can maintain underneath excellent situations and when paired with an equal or higher check system in a lab. We focus on this intimately in our article on easy methods to decode the letters and numbers in Wi-Fi router names, however right here’s a fast overview:

Let’s say you’ve a router that’s labeled as AC1900. That letter and quantity mixture signifies the technology of Wi-Fi (AC is technology 5) and the utmost bandwidth the router can maintain underneath supreme situations (on this case, 1900 Mbps throughout all of the router bands/radios.)wss

Whenever you’re utilizing your iPhone, Xbox One, or no matter system in your Wi-Fi community, you’re restricted to the connection that system has negotiated with the Wi-Fi router. Except you occur to be utilizing a contemporary system with an historical single-band router (during which case you possibly can doubtlessly truly max out the out there bandwidth) you’ll by no means see a single system use all of the bandwidth a router has to supply.

On that AC1900 router, as an illustration, the bandwidth is split between a single 2.4Ghz band that maxes out at a theoretical 600 Mbps and a 5 GHz band that maxes out at 1300 Mbps. Your system will both be on one band or the opposite, and may’t reap the benefits of the total capability of the router.

Most Machine Speeds Are Theoretical, Too

Whereas we’re speaking about theoretical speeds, it’s additionally essential to notice that the utmost velocity for a single band can be largely theoretical. A tool utilizing Wi-Fi 5 (802.11ac) on the 5GHz band can theoretically stand up to 1300 Mbps however in apply, it’s going to solely get a fraction of that.

Due to overhead within the Wi-Fi protocol, you may anticipate anyplace from 50-80% of the anticipated “advertised” velocity primarily based in your gear. Newer routers paired with newer units are extra environment friendly, older units and older routers, are much less so.

If you happen to run a velocity check on a gigabit connection and your Wi-Fi system solely will get a portion of that velocity it’s to be anticipated. It’s additionally, by the way in which, why you shouldn’t use your cellphone for velocity assessments.

Sadly, there’s no means to make use of suggestions, methods, or hacks to get round this limitation. The distinction between the way in which router and system speeds are marketed and the way in which they’re truly realized throughout real-world use is at all times going to be out of alignment.

Your Units Are Slower Than Your Router

Someone using their iPhone and laptop on a Wi-Fi connection.

Assuming you’re not working into Wi-Fi points as a result of you’ve an historical router, the person purchasers are possible the bottleneck. Even underneath supreme situations, there’s probability that your router can run circles round your units when it comes to transmission energy and bandwidth capability.

You probably have a router with a 4×4 MIMO functionality, as an illustration, however the units you’re connecting to the router solely assist 2×2 MIMO, then it’s unattainable for that system to even start to strategy the utmost velocity the router can deal with.

As of the time of this text, April 2022, configurations higher than 2×2 MIMO are hardly ever discovered exterior of routers or Wi-Fi entry factors. Some Apple laptops have 3×3 setup, and some high-end Dell laptops have a 4×4 setup, however practically all the pieces else solely has 2×2 MIMO. So even when your router is a Wi-Fi 6 (802.11ax) router and your units assist Wi-Fi 6, there may be nonetheless an imbalance of radio association and transmission energy between your system and the router.

Till most units sport the {hardware} equal to the router and have comparable transmission energy, you’ll at all times be restricted by the system.

So What Ought to You Do About It?

In case your concern was merely that the velocity you noticed in velocity assessments or when downloading massive information didn’t match what you anticipated, there’s actually nothing it is best to do about it now that you already know why it occurs.

There aren’t actually any day-to-day actions the place maxing your Wi-Fi connection to get nearer and nearer to that theoretical velocity issues that a lot. How a lot bandwidth you want for numerous web actions is surprisingly low. Even an outdated Wi-Fi 3 (802.11g) router has sufficient bandwidth capability to stream HD video to your sensible TV or iPhone.

Actually, what issues greater than any particular person system getting a blazing quick single connection to your router is the power of your router to assist a number of units with ease. For the overwhelming majority of individuals, it’s way more helpful to have a router that may deal with a family filled with Wi-Fi units than to have a router that may ship their complete broadband bandwidth capability to 1 system. No one wants a gigabit connection fire-hosed to their iPhone, they want that connection correctly allotted throughout all of the smartphones and units in the home.

If you happen to discovered your self studying this text not as a result of some benchmarks had you curious why you weren’t getting the marketed router velocity you anticipated, however as a result of your Wi-Fi units are struggling and primary residence web actions like streaming video and gaming are a laggy mess, a router improve might be so as. Assuming you’ve an satisfactory broadband connection, the perpetrator is sort of at all times that your router can’t sustain with the calls for your family imposes.

For the overwhelming majority of individuals, they don’t want extra bandwidth, they want higher system administration and bandwidth allocation—and a shiny new present technology router has the {hardware} to make that occur.
