Obstructions are physical obstacles like walls and trees or large metal objects such as a refrigerator. Interference often comes from noise created by other wireless routers, cordless phones, baby monitors, etc. Interference and obstructions greatly affect the range and quality of a wireless signal. However, keep in mind that because there are more 2.4GHz wireless networks, the frequency channels can become crowded in some areas. It just doesn’t handle obstructions and channel noise quite as well. However, 5GHz offers much faster throughput for maximum performance. 5GHz is a regulated frequency which costs manufacturers more to produce. The downside to this “unregulated” band is that manufacturers use it for everything: cordless phones, baby monitors, microwaves, garage door openers, etc. As a result, vendors can manufacture 2.4GHz devices less expensively than regulated spectrum like the 5GHz band. There are basically two frequency bands used for Wi-Fi technology, 2.4GHz and 5GHz. In fact, each frequency band has its own advantages and disadvantages. This is why you’ll often see “IEEE 801.11a/b/g/n” on retail boxes for wireless devices, routers, etc.Ĭontrary to the marketing hype, Wi-Fi spectrum is not based on speed alone. These Wi-Fi spectra are established by The Institute of Electrical and Electronics Engineers, a non-profit organization also known as the IEEE. When I say, “the same language” I’m referring to the same signal frequency and the same wireless spectrum. In order to receive the broadcast and communicate with the transmitter, the client device must have a Network Interface Controller (NIC) capable of speaking the same language. Corresponding TCP/IP packets are sent back to the transmitter where they are routed either inside or outside of the network. That signal is received by a client device. In a Wireless LAN (WLAN) environment, a signal is broadcast from a radio transmitter. Wireless routers have radio transmitters built-in. But if your WiFi is not working properly it is often a symptom of interference that can be fixed with some minor tweaks. It’s also one of those amenities like water and electricity –you just want it to work so you can flip a switch and enjoy the magic! The fact is, there are a number of things that can affect your WiFi performance, such as:Īll of these things contribute to the overall performance of the network. When you log in to your router's web app you'll find it under the basic menu in the sidebar. This will help to intelligently prioritize bandwidth to make sure that the most important and demanding tasks, like streaming video and gaming, for example, are getting the share of the bandwidth they need. By default, it'll have 5G at the end of the SSID.Īnother thing to try is enabling Netgear's Dynamic QoS (Quality of Service) feature that is supported on some routers. On Netgear routers, you'll see the 5GHz connection as a separate Wi-Fi network in Windows. Typically, 2.4GHz is for distance, 5GHz is for performance. A lot of modern routers are dual or tri-band, offering 2.4GHz and 5GHz connections. One easy trick is to use the 5GHz connection if your router supports it. Pick a different one to the default and see if that helps. In the wireless settings this time you're looking for channel. If there are other networks nearby using the same channel, it could get congested and as such your speeds may suffer. You could try changing the channel that your Wi-Fi signal is using. If you can't move the router to a more central location, there are some things you can do. The size of the house will be one contributing factor, as will the positioning of the router. ![]() This one is more difficult to solve, as it might not be just down to the router.
