Finding the most suitable WiFi channel can improve your wireless experience tremendously. But it's not just the speed you should be looking at, the overlapping is an important factor as well. The most popular WiFi channels for 2. Use these channels with a non-MIMO setup i. Starting with the If you purchased your router within the last couple of years, chances are you have either a The 5 GHz band offered with these specifications provides lots of free space at the higher frequencies — 23 non-overlapping 20MHz channels — and the router will choose the best wireless channel for your connection automatically.
Using the 5GHz band in a space with thick walls usually means very little WiFi interference. There are two frequency bands that you can choose from: 2. Newer routers support both of these bands and it's up to you to decide which one works better for your connection. The 2. The 5 GHz band coverage doesn't travel far, but is very fast and can penetrate obstacles better than 2. NetSpot can visualize your network coverage to help you see the possible reasons for any wireless issues.
NetSpot can also help you choose the best channel for your network. Simply open the NetSpot app and click Discover; then click the "Channels 2. Look for the channel out of 1, 6 and 11 with the least number of networks using it. You can easily scan for WiFi channels using a wireless channel scanner like NetSpot. NetSpot can scan WiFi channels in the 2.
There are three non-overlapping channels in the 2. Yes, it does. Using a channel exposed to too much signal interference can dramatically degrade your WiFi experience, causing slowdowns and even connection drops. Get NetSpot. NetSpot WiFi channel scanner. Jump to Wi-Fi channels 1, 6, and Non-Overlapping Channels. What wireless channel to use in a crowded space. What if Wi-Fi channels 1, 6, and 11 are crowded? Three main reasons for WiFi interference. Should I Use the 2. Wi-Fi channels 1, 6, and 11 In your router's settings there are channel settings.
Wi-Fi channels. Non-Overlapping Channels As said above every wireless channel on the 2. What wireless channel to use in a crowded space And, again, for the best throughput and minimal interference, channels 1, 6, and 11 are your choice.
Three main reasons for WiFi interference All Wi-Fi connections can be negatively affected by electromagnetic interference, also called radio-frequency interference , which happens for three main reasons:. WiFi interference. Reason 1: Co-Channel Interference In networks where devices take turns to talk, it takes time for each of them to wait for their turn. Reason 2: Adjacent-Channel Interference Adjacent-channel interference happens when clients on overlapping channels talk at the same time.
Reason 3: Non-Wi-Fi interference In addition to Wi-Fi routers, there are many other electronic devices that can interfere with the 2. Windows Windows provides a native way of finding the best WiFi channel, but it relies on a rather unintuitive command-line application, called netsh. Launch NetSpot and make sure Discover mode is selected. Sort the discovered WiFi networks by their channel. Determine which non-overlapping channel 1, 6, and 11 is utilized the least.
Configure your router to use the least used channel. Launch NetSpot and click Discover in the top-left corner. Configure your router to use the least used non-overlapping channel. Follow these steps to find the best WiFi channel using iwlist: Open Terminal. You can exclude a certain channel from the comparison by tapping the small checkbox next to it. Turn on the Wi-Fi Scanner feature at the bottom.
Set the desired scan duration and tap Scan. Look at the list of available networks. Switch to the comparison tab for a visual representation of WiFi channel distribution. Select the right Wi-Fi channel with NetSpot — the top WiFi channel analyzer As explained in this article, channel overlapping leads to co-channel interference, which can dramatically degrade WiFi performance and cause annoying slowdowns and other issues.
WiFi channel analyzer. Which channel is best for WiFi? How do you analyze WiFi channels? What does WiFi analyzer do? What is the best channel for WiFi 5 GHz? Which WiFi channel is the fastest? If using 40 MHz channel width, the bandwidth of the following channel is used:. If using 80 MHz channel width, the bandwidth of the following channel is used:. This means the wider the channel width used, the higher the chances that access points will overlap each other in the same radio spectrum.
If you have a sparse network with a few access points and not a lot of users, such as a home or small office, you should probably use 80MHz channel width to maximize per-client performance. Meanwhile, if you have a dense network with a lot of access points and clients, then using 40MHz channel width may help reduce the chances that access points and clients interfere with each other.
While 5 GHz offers greater performance, its distance is reduced compared to 2. DFS allows the access point to switch channels if it detects military or weather radar already in use on the channel. DFS is live as of access point firmware version 6. If you do not want to manually set your own channels, you may be better served by enabling Auto Channel Mode.
