By increasing the channel width, we can increase the speed and throughput of a wireless broadcast. By default, the 2. A 20MHz channel width is wide enough to span one channel. A 40 MHz channel width bonds two 20 MHz channels together, forming a 40 MHz channel width; therefore, it allows for greater speed and faster transfer rates.
Obviously, two channels are better than one, right? In theory, yes. But not if those channels are crowded with noise and interference. In crowded areas with a lot of frequency noise and interference, a single 20MHz channel will be more stable. However, noise and interference is not always the issue. If greater distance is the primary objective, my preference is the 2.
If you discover that all of your neighbors are using the 2. Channels 1,6,11 are preferable for the 2. This is like traveling on an open highway that no one else is using. For my particular situation, the 5GHz band provides a more reliable connection. Not to mention that I had 25 neighbors trying to share a handful of preferred channels on the 2. Granted, the range is not quite as far with 5GHz but it is acceptable throughout the entire building. First and foremost, it may not be necessary.
If my area was not so crowded, I would have preferred to stick with my Unfortunately, with so many access points nearby, changing the channel on my 2. When that happened, their broadcast created enough noise to disrupt communication between the router and the wireless card on my laptop.
Bye-bye Internet connection. The only exception is that you somehow has a devices that support 5 Ghz broadcasting while only accepting a 20 Mhz bandwidth, however that is fairly uncommon.
But if that does happen, see if your router supports duo bandwidth for both 20 Mhz and 40 Mhz. If you use 5 Ghz broadcasting radio, the chances are that your network is only consisted of the latest devices that support This is when you should use the 40 Mhz bandwidth. If not, just set it to 40 Mhz. For 20 Mhz broadcasting with 2. For 40 Mhz broadcasting with 2. The main difference between the two is the speed. In ideal conditions or on paper, the 2.
However, the value for the 5 GHz band varies depending on the class and model of the router. The speed may go up to Mbps on the latter channel band. To understand routers better and all the features listed on router boxes, it is important to know what the radio bands are.
The 2. Almost all devices from cordless phones, remote controls and baby monitors operate on the 2. This is because this channel band usually has longer waves compared to the other band.
Because of this, you will find that the band provides longer range and can transfer easily through walls and other obstructions. However, due to the congestion of the channel that we mentioned earlier, the speeds will be much slower on this channel — slower than the expected speeds from the router. Today, we are lucky enough to have routers that provide both channels from the same device.
And this is because of dual band and triband capabilities that routers have. The following section shows what dual and triband routers mean in relation to the 2. A dual band router offers both the 2. Since some routers do not allow you to switch between these bands, you need a switch to be able to do this. With the growth of technology came simultaneous dual band routers.
Here, the routers broadcast on both the two channel bands at the same time. By doing this, the router gives you two Wi-Fi networks to choose from. To know whether you have a simultaneous dual band routers, you will see that there are two networks in your house where one is the regular band with your router name and the other features the brand name of the router.
You can choose either the same password for both or different ones. But the advantage of having two operating bands at the same time makes them a much more valuable buy.
