Slow or Sluggish Wi-Fi?


I have often been presented with a question by new customers concerning their wireless networking. Why is my wi-fi coverage so poor and so slow? First, let me frame the scenario. Most of the time these are small business that have already installed a wireless network. This may have been done by themselves or a technical services company they had worked with in the past.

The answer to the question is usually simple but not direct. The answer is that someone like Systech must survey the wireless network and discover the issue, then provide a plan to correct the problems.

Wireless networking is not easy because most of the time the customer and even the service provider do not have the tools necessary to service a wireless network. It is very difficult to manage what you cannot see. So, if your service provider has no way of conducting a wireless network survey, then the results will likely be very poor.

Some of the most common problems with existing wireless networks are:

  • There are not enough access points (APs). Often, there are not enough APs to cover the area required. Depending on the type of AP and its location – you simply may not be able to cover the entire area effectively.
  • There are too many APs. This may seem contradictory with the first point but too many APs cause signal deflection, channel confusion, and general failures as the many signals drown each other out and cause inconsistencies in the wireless network.  
  • The APs are designed for home use. Home use access points are cheaper for a reason and you get what you pay for. Traditionally, these types of APs only support a fixed number of concurrent connections at any given moment causing random disconnects. They also may not be able to handle the physical conditions of a business, such as high heat in the ceiling of a warehouse. Furthermore, they are not designed to work in concert with other APs. This will cause problems – such as wi-fi disconnects – when devices roam inbetween two access points and the hand-off fails. 
  • There are channel conflicts. Sometimes, especially in large office complexes, there are many other wireless signals from your neighbors that may already be using a channel frequency that is already in use which makes it next to impossible for the access point to function as it should since APs use differing wi-fi channels and frequencies to broadcast their signals. Lower cost access points have less options for frequency and channels which limit their effectiveness in certain environments. (e.g. sometimes cell phones do not work in proximity to baby monitors because they both use the 2.4Ghz wireless frequency.)
