Wireless is becoming an indispensable part of modern life. No matter you use iPhone or Samsung or Kindle, wireless speed will determine your efficiency and even your mood. However, nothing is perfect; here are always some wireless speed problems to hinder you. Now, let’s pick out the come wireless speed problems and simple ways to faster the network:
Problem 1: Oversubscription to the wireless
How is it that a campus Wi-Fi network could have strong signal strength all over campus, have great wired infrastructure, a big internet pipe, and still have crappy wireless performance? Simple, the wireless network was planned in a coverage model not a capacity model. When 50 users are connected to the same access point and share that bandwidth (divide the available speed by 50). When you only have a few users, the coverage model works great. When you’re a school or a hospital with high density lecture halls or areas, you’re going to have problems.
Solution: Look at how many devices (not just users) will need to connect at any given time in a specific area. Make sure you’re wireless plan takes that into account.
Problem 2: Video Streaming, Gaming, and Media hurt performance
YouTube is great, Netflix is awesome, but both can wreak havoc on your wireless network. Many wireless solutions are built to provide wireless guest access as well as business wireless use. But when you combine the two, you can lose the fight in productivity.
Solution: Wireless Performance is about managing how the system is being used. Specifically, you’ll need to provide some level of application prioritization. This is called QoS or application optimization. Simply put: business stuff has to take priority over Netflix.
Problem 3: Slow Wired Infrastructure wireless network speed
This is probably the most common issues we see: a school goes out and buys the fastest wireless system available today, but the provider fails to tell the school administrators that they may need to address the stuff connecting the wireless access points to the campus network.
Solution: Consider the entire network infrastructure when looking at adding or expanding a wireless network. This would include the switches, wiring, firewall, and your internet connection. What is the lowest common denominator? The lowest connection speed on your network is as fast as the wireless could ever go. Chances are you’ll need to upgrade some of those components to get the proper speeds.
Problem 4: Use of old security standards
This one really throws people off sometimes. But you can actually have the latest wireless technology (which is 802.11n currently). You could have dual or even three radio access points that can allow for speeds of up to 600 Mbps, but still only be getting a max rate of 54 Mbps.
How could this happen? The wireless networks with the faster speed technology don’t support the older types of authentication and encryption.
Solution: Evaluate the security you have on the wireless networks you have on campus. You’ll need to use WPA-2 or better. For example: WPA-TKIP is not a recognized security standard for the fast wireless connections. If you’re using it in your hospital or school, the fastest speed you’ll have available on that network is 54 Mbps….pretty crappy.
Problem 5: The wireless access points are installed improperly
Wireless speeds consider a flashlight: when you turn one on, it reflects light a specific way. A small hand held flash light shines light in a small area while the larger ones you might keep in your car are made to cover a much larger area. Wireless Access Points work in a similar way in that they were designed to shoot the signal in a specific direction. The problem of course, is that you can’t see the radio signal, so you might be shooting the signal away from the areas you’re trying to cover.
Solution: Are access points thrown above the ceiling or sitting on a shelf in the back of the room? This is not the way they were intended to be used. Check out the manufacturers intended coverage pattern and make sure they are mounted properly.
