3 Common Wi-Fi Performance Mistakes and What You Can Do to Avoid Them

Written by Danny Mareco Danny Mareco | March 9, 2017

Having reliable Wi-Fi performance is like having electricity today. It’s not a luxury it’s a utility—a basic requirement for all businesses and organizations to operate.

Trying to deliver the required infrastructure to successfully accomplish this task comes with many challenges; challenges that require experience and the right qualifications to solve.

This is where many businesses get themselves into trouble. Without knowing how enterprise grade wireless works, mistakes are made--and all of them are costly, both in performance and in dollars.

To help you achieve reliable wifi performance and to maximize your budget, here are 3 common mistakes and what you can do to avoid making them.

AP Swap

Imagine you’re a school and you’ve finally concluded that your old 11n or older access points are to blame for your increasingly poor wifi performance. You figure I’ll just remove the old ones and put up shiny new 11ac APs in their place, problem solved, right?


Unfortunately, this just isn’t how it works.

You can’t just purchase new access points and put them up where your old APs used to be, this is what we call AP swapping. 

If you choose the swap out method, you’re almost certainly going to run into wireless performance problems, and in most cases, also end up spending more than necessary.

We can’t say it enough! Your wireless network is dynamic; it needs precision and coordination when any changes are being made, especially when it comes to deploying new access points.

Your new APs will have different capabilities and configurations than the legacy components they’re replacing.

To get the most reliable performance out of your new access points, many factors will need to be adjusted such as:

  • Number of APs
  • AP placement
  • And Configuration

Therefore, it’s important to always come back to your WLAN design when making big changes like replacing out dated APs.

Over or Under Engineered WLAN Design

Having too many or not enough access points is not good, however, it’s something we come across all too often.

Typically, this happens when you work with inexperienced consultants who use free design software or don’t know how to properly use the right software.

Do your research, cheaper doesn’t always mean better just as costly doesn’t necessarily mean the best.

While it might seem like the more access points the better, having too many in one area can cause more issues i.e. CCI and ACI (co-channel interference and adjacent channel interference).

Just as too few access points won’t be able to properly support large numbers of devices.

Trying to Design your WLAN Yourself

Most people think about wifi as the little router in their house, that you just plug in and “that’s it.” However, enterprise grade wireless is not symmetrical with consumer grade wireless.

If you think that way, your wireless network performance is going to suffer, BIG TIME!

WLAN design takes years of experience and, requires a multitude of certifications to get it done right.

Partnering with the right wireless service provider is the difference between money well spent and great on-going wifi performance, and having to spend even MORE money to compensate for erroneous measures taken and awful performance.

Want to guarantee awful Wi-Fi performance, sounds strange right? Watch the video below to learn more:

For most if not all IT teams, wireless is just one part of their overall responsibilities, and when it comes to wireless going it alone, even for seasoned IT managers, is a costly mistake.

In Conclusion

While there could be a much longer list of things to avoid, these are 3 of the most common mistakes we consistently see being made.

Enterprise grade wireless networks are complex, dynamic systems that take constant education and practice to master.

From having proper coverage and designing for capacity to ensuring air-tight security and delivering a reliable, high-performing wifi experience to your end-users, enterprise grade wireless isn’t short of complex challenges.

Before you purchase, make sure to plan, and before you plan make sure you partner with an experienced wireless service provider.
