Overlapping makes wireless network throughput quitepoor. Most popular channels for 2.4 GHz Wi-Fi are 1,6, and 11, because they don't overlap with one another. You shouldalways try using channels 1, 6, or 11 when on a non-MIMOsetup (i.e. 802.11 a, b, or g).
Test Wi-Fi speed to devices on your network
- Open the Google Wifi app.
- Tap the tab, then Network check.
- On the network check screen, tap Test Wi-Fi.
- We'll test one Wifi point at a time, showing speeds for eachdevice connected to that Wifi point.
- You'll see the speed results for each device in large text atthe top of the screen and next to the device name below.
Using the Admin Tool
- Connect to your WiFi network.
- Go to Gateway > Connection > Wi-Fi. To change yourChannel Selection, select Edit next to the WiFi channel (2.4 or 5GHz) that you'd like to change, click the radio button for thechannel selection field, then select your desired channelnumber.
- Select Save Settings.
Here are five easy ways to boost your WiFi router's rangeand speed at home or at the office:
- Put your WiFi router in its (proper) place. The right place,not under the kitchen sink.
- Switch the channel. TVs aren't the only gadgets that havechannels you can change.
- Buy a high-gain WiFi antenna.
- Buy a plug-in extender.
To change the wireless channel:
- Launch a web browser from a computer or mobile device that isconnected to your router's network.
- Enter the user name and password. The user name is admin.
- Select Wireless.
- From the Region menu, select your region.
- Select a number from the Channel menu.
- Click the Apply button.
The answer is that they both work well, depending onyour needs. Let's see in what cases it is best to use either2.4 GHz or 5 GHz WiFi frequency to provide a well-performingwireless experience.
Often referred to as the 2.4 GHz band, thisspectrum is the most widely used of the bandsavailable for Wi-Fi. Used by 802.11b, g, & n. It cancarry a maximum of three non-overlappingchannels.

The great thing about 5GHz (802.11n and 802.11ac)is that because there's much more free space at the higherfrequencies, it offers 23 non-overlapping 20MHzchannels.
Selecting the proper WiFi channel cansignificantly improve your WiFi coverage and performance. Inthe 2.4 GHz band, 1, 6, and 11 are the only non-overlappingchannels. Selecting one or more of thesechannels is an important part of setting up your networkcorrectly.
The biggest difference between the two is speed.Under ideal conditions, 2.4 GHz Wi-Fi will support up to 450Mbps or 600 Mbps, depending on the class of the router. 5 GHzWi-Fi will support up to 1300 Mbps.
A WiFi channel is the medium through which ourwireless networks can send and receive data.
WPS stands for Wi-Fi Protected Setup. It is awireless network security standard that tries to make connectionsbetween a router and wireless devices faster and easier. WPSworks only for wireless networks that use a password that isencrypted with the WPA Personal or WPA2 Personal securityprotocols.
Passband bandwidth is the difference between theupper and lower cutoff frequencies of, for example, a band-passfilter, a communication channel, or a signal spectrum.Baseband bandwidth applies to a low-pass filter or basebandsignal; the bandwidth is equal to its upper cutofffrequency.
2.4Ghz networks have two options: 20MHz (the'normal' bandwidth) and 40MHz (doubled). It is HIGHLYrecommended that you only use 20MHz-wide channels, as usinga 40MHz channel will overlap with others, causing a decreasein performance or, generally speaking, troubles.
802.11n (Wi-Fi 4)
The first standard to specify MIMO, 802.11n wasapproved in October 2009 and allows for usage in two frequencies -2.4GHz and 5GHz, with speeds up to 600Mbps. When you hearwireless LAN vendors use the term “dual-band”,it refers to being able to deliver data across these twofrequencies.To connect to a 2.4GHz network, go toSettings ( )>Wi-Fi. In this menu you will see alldetectable networks in your area. Locate the SSID for your network,and tap on the SSID with the 2G or 2.4 end notation.Connect to that network using the Wi-Fi passwordassociated with your network.
5 GHz WiFi routers are more dangerousbecause they are twice the frequency with more intensity than thestandard 2.45 GHz models. In the Radio Frequency (RF) Radiationworld, the higher the frequency the more dangerous it is tous. 2.45 GHz is the same frequency your microwave oven uses to cookfood.
Your Wifi point(s) uses the same name forboth the 2.4 and 5GHz band networks. This means yourWi-Fi network uses both radio bands. But keep in mind: whileboth bands can be used, your personal devices (asmartphone, tablet, laptop, etc.) will connect to only oneradio band at any given time.
If you want better range, use 2.4 GHz. Ifyou need higher performance or speed, the 5GHz bandshould be used. The 5GHz band, which is the newer ofthe two, has the potential to cut through network clutterand interference to maximize network performance. But by design,5GHz can't reach as far as the 2.4GHz.
A general rule of thumb in home networking says thatWi-Fi routers operating on the 2.4 GHz band reach upto 150 feet (46 m) indoors and 300 feet (92 m) outdoors. Older802.11a routers that ran on 5 GHz bands reachedapproximately one-third of these distances.
A 5GHz wireless LAN will almost always beslower than 2.4 GHz - the 5GHz frequencies aresubject to greater attenuation so that you end up with a weakersignal at the same distance. Given the same levels of noise, aweaker signal results in a lower SNR (signal-to-noise ratio) and alower quality connetcion.
Today's WiFi gear operates at either 2.4GHz or5GHz. Their higher frequencies make it harder for thesignals to maintain their strength as they passthrough obstructions. According to the WiFiAlliance, 802.11ah will also achieve nearly double the rangeof current standards. There's another bonus, too.
If you don't turn off your wifi router,you're being exposed to its EMF radiation emissions when you're noteven using it! Think about it. You and your family sleep somewherebetween six and nine hours a night. The simple act ofturning off your wifi router at night will cutout that radiation exposure entirely.
Method 1Using General Tips
- Know your router's maximum range.
- Remove obstructions from your router's path.
- Position your router for optimal performance.
- See if you have signal interference.
- Make sure your router is using the 2.4 GHz channel.
- Use an unofficial range extender.
- Upgrade your old router.
How to Use the 5-GHz Band on Your Router
- Log into your account. Open your browser and enter themanufacturer's default IP address, typically located on theunderside of your router or in the user manual or a custom one thatyou set.
- Open the Wireless tab to edit your wireless settings.
- Change the 802.11 band from 2.4-GHz to 5-GHz.
- Click Apply.
The WLAN administrator must designate which 20MHz segment within a 40, 80, or 160 MHz widechannel is the primary 20 MHzchannel.
In the 5 GHz band, no 20 MHz channelspartially overlap. In addition to this, there are 24non-overlapping channels to work with, so making sureno same-channel cells touch is mucheasier.
In an environment with less congestion where ahigher data throughput is required, using the 40MHzchannel can be a good idea as it still offers 12 non-overlappingchannels on 5GHz. 80MHz is available on many 802.11acrouters and offers an even wider channel and as such evenhigher bandwidth.
A total of twenty-five 20 MHz channels in the5 GHz bands can be utilized when designing a WLANwith a channel reuse pattern— but the channelsyou can actually use depend on regulations enforcedin each country.
Using the Admin Tool

- Select Save Settings.
Microwave ovens, cordless phones, and baby monitors areall common sources of interference on the 2.4GHzfrequency band. The 5GHz frequency band sees a lot lessinterference than the lower 2.4GHz frequencyband.
