An RF spectrum analyzer is the instrument of choice for detecting and identifying sources of RF interference and monitoring the health of a wireless system. An RF spectrum analyzer measures the raw RF energy of transmitted radio frequency signals and aids the user by providing a view into the local RF environment. This RF view can be used to help detect the presence of RF transmissions that are the source of interference. Armed with this information you can either attempt to track down and eliminate the source of RF interference or choose to re-configure your own wireless gear to operate in a different freqency range of the RF spectrum that is less prone to RF interference.

Slow connectivity in an area can be caused by competing networks on the same or overlapping channel. When a WiFi channel has a lot of active users on several networks, the speeds decrease for everyone. Unfortunately, the channel doesn’t belong to just you, and you can’t stop other networks from using it.
Your best option is to use a channel with no overlapping networks or share a channel that has networks with low signal strength. There are two types of WiFi interference that can slow you down:
Co-Channel Interference - Networks sharing a channel cooperate and take turns talking. Channel bandwidth is shared between every WiFi device.
Overlapping Interference - Networks on non-standard or overlapping channels are unable to cooperate, and will cause interference on neighboring networks. They share bandwidth with networks on standard channels.
inSSIDer’s algorithm only measures the signal strength of a single wireless router and assumes each competing network is equally active. (For more accurate interference assessments, you will need to use more advanced tools like Spectrum and Packet Analyzers).
To avoid WiFi slowness, find a channel that has the least amount of co-channel and overlapping interference. That means you want the fewest networks to be on your channel - and if they are, you want them to be relatively quiet (lower signal strength).
This exercise assumes you have already found an ideal central location for your wireless network. It also requires you to know how to configure and change the channel of your wireless router. If you do not know how, please consult your user manual. Iexplorer 4 2 9 0.
inSSIDer will display a link score for your network, which is a number that accounts for signal strength as well as the level of co-channel and overlapping interference. The Link Score is an estimation, and it assumes that each network is equally active.

Sometimes you may have excellent signal strength, but little to no connectivity. These dead spots can be caused by competing wireless devices that use the same frequencies as WiFi, but do not cooperate with WiFi. Here are a few common devices that cause dead spots in the home:
In short - no! Many wireless modems and routers have an auto-channel selection algorithm in order to provide a better connection, but this can cause more headaches than it solves. Auto channel selection is blind to non-WiFi sources, and makes its selection only on the number of interfering networks sharing the same channel. It may also put your wireless network on a non-standard channel, which introduces even more interference from multiple sources. In the end, auto channel selection does not solve any problems. If anything, it makes the problem more intermittent and extremely difficult to troubleshoot. The best long-term solution is to use a tool like inSSIDer (small networks) or Chanalyzer (complex networks) with a Wi-Spy DBx to monitor your WiFi environment and assign your access point to the channel with the least interference.
Without a spectrum analyzer, it is difficult to definitively conclude anything regarding non-WiFi interference. Learn more about spectrum analysis.
The following steps will help you systematically test other wireless devices for WiFi interference:
Slow zones and dead spots can occur for a variety of reasons. You can avoid these pitfalls by moving your wireless router to a central location and choosing a better channel, which we've learned about this this lesson.
