So in reality you should just try channels within the various 5Ghz bands and see which gives a better signal. Then choose the lowest channel within that band. The higher bands have higher power limits because they don't penetrate as well so cause less interference.
On the 5 GHz band, set the channel width to 40 MHz and see if that improves reliability. Keep in mind that 80 MHz and 160 MHz channel widths may carry the promise of extra speed, but will also interfere with, and receive interference from, many more sources than 40 MHz.
Here is a short summary of some recommendations for each frequency band: 2.4 GHz – Use 20 MHz wide channels only and use channels 1, 6 & 11. 5 GHz – Use 20 MHz wide channels in highly congested networks. If your environment allows, use the widest channel you can without causing contention on your network.
If you're able to use most of your devices near your router, 5 GHz is your best choice to take advantage of higher speeds. Similarly, if you're doing a lot of high-bandwidth activities online, such as gaming or videoconferencing, it's best to use this frequency and move as close as possible to the router.
Auto or all channel widths for 5GHz and 6GHz bands ensures the best performance and compatibility with all devices. Wireless interference is less of a concern in these bands.
On the 5 GHz network, set your radio on the 5GHz to A/AC/N. This will allow all devices to connect to this network. If you want to optimize your home network, choose just AC and it will not allow older slower N wireless devices to take up bandwidth on this radio.
Ideally, you'll want to run your 2.4GHz wifi network on channels 1, 6, or 11. You should be able to set your wireless network to a new channel within your router's settings. (And don't forget to do this same analysis for your 5GHz wireless networks as well.)
So, why are some 5G connections so slow? The first, and most impactful, reason is that the far-reaching 5G signals that have powered the vast majority of carrier rollouts in the US – especially from AT&T and, to a lesser extent, T-Mobile – have used low-band carrier frequencies.
A 2.4 GHz connection travels further at a lower speed. A 5 GHz frequency provides faster speeds at a shorter range. Both 2.4 GHz and 5 GHz frequencies are also divided into numerically labeled channels.
Given the same transmitter output power, in the absence of ANY interference, the lowest-frequency channel will nearly always be the best. This is because higher-frequency radio waves do not penetrate matter (including air) as well as lower-frequency waves.
80MHz theoretically doubles your throughput compared to 40MHz but even in practice, it is one of the best ways of getting improved throughput on 1-stream and 2-stream devices.
To recap: 80 MHz wide channels allow for five (5) non-overlapping channels in the U.S. and five (5) in the UK/EU (channels 149 and higher require light licensing for outdoor use only) when DFS is used, but only two (2) channels in the U.S. and one (1) in UK/EU without DFS.
2.4 GHz has three non-overlapping channels to work with, while 5 GHz has 24. We don't always get to use all of the 5 GHz channels, but overall it offers a lot more space.
Selecting the proper Wi-Fi channel can significantly improve your Wi-Fi coverage and performance. In the 2.4 GHz band, 1, 6, and 11 are the only non-overlapping channels. Selecting one or more of these channels is an important part of setting up your network correctly.
The most known standard that it (5 GHz) is supported is on and the 802.11ac. Therefore the standard is dependent on the speed a connection encompasses and they bring the difference in both differences in speed of the WiFi and Ethernet.
Ideally, you should use the 2.4GHz band to connect devices for low bandwidth activities like browsing the Internet. On the other hand, 5GHz is the best suited for high-bandwidth devices or activities like gaming and streaming HDTV.
A 5 GHz router can only emit signals on the 5 GHz band. The basic difference between these two bands is speed. Under ideal conditions, a 2.4 GHz Wi-Fi router can support speeds up to 450 Mbps, some up to 600 Mbps. Under ideal conditions, a 5 GHz Wi-Fi router can support speeds up to 1300 Mbps.
The difference between the two is pretty simple: it all comes down to range and speed. 2.4 GHz has a longer range, meaning it reaches a lot further than 5 GHz Wi-Fi. 1 However, even though you can connect to 2.4 GHz Wi-Fi from your basement, it will have a slower speed. 5 GHz Wi-Fi is faster.
In general, 36, 40, 44, and 48 are the best 5G channels WiFi because they are least likely to overlap with other channels. However, if these channels are already congested in your area, you can try using channels 149, 153, 157, and 161 as they are also less likely to overlap with other channels.
If you want maximum throughput and minimal interference, channels 1, 6, and 11 are your best choices. But depending on other wireless networks in your vicinity, one of those channels might be a better option than the others.
The most popular WiFi channels for 2.4 GHz frequency are 1, 6, and 11, because they don't overlap with each other. Use these channels with a non-MIMO setup (i.e. 802.11 a, b, or g).
Just about any electronic device that operates around the 5GHz range can interfere with a 5GHz WiFi connection. Microwaves, wireless phones, amateur radio transmissions are only a few of the many things can cause RF noise that can interfere with a router.
Using a 5Ghz frequency, you will get about 50 feet or about 15 meters of reach. The reach of your signal will be impacted by the manufacturer of the equipment that you are using, the location your router is installed, and the obstructions that might block the signal in your home or business.
In some cases, turning off 5GHz may improve WiFi because it can reduce interference and improve the stability of the connection. However, in other cases, turning off 5GHz may actually worsen WiFi because it can limit the available bandwidth and reduce the overall performance of the connection.
