If you have a dual-band router, it can provide both 2.4 GHz and 5 GHz Wi-Fi at the same time. But your device itself will only connect to one Wi-Fi frequency at a time. Although it's a sweet idea, your device can't use both simultaneously. You'll have to switch between both.
Simultaneous dual-band routers are capable of receiving and transmitting on both 2.4 GHz and 5 GHz frequencies at the same time. This provides two independent and dedicated networks which allows more flexibility and bandwidth.
It's usually a good idea to enable both bands. 2.4 GHz has better range and many IoT or older devices only can use 2.4 GHz. 5 GHz has higher potential speeds and less interference from other wireless devices than 2.4 GHz, some computers and phones can have a significantly faster connection using 5 GHz.
The idea is to spread out your devices over the two bands so that there's less competition for the same channels. Separating your personal and Internet of Things (IoT) devices can also help your WiFi security. By splitting your devices between 2.4GHz and 5GHz, you can maximize your network's performance.
Select Wi-Fi. For Telstra Smart Modem 1.1 and Gen 2: You'll see Guest tabs for both the 2.4GHz and 5Ghz. For each tab, tick the Enabled option if you want that network to be available. You can also configure your own network name and password, or take note of the name and password generated.
Disable a Band on Your Router Settings
The most foolproof method would be to disable one band or the other entirely. Just keep in mind that some older devices cannot connect to a 5GHz network at all, so if you do disable your 2.4GHz network, that's likely to cut certain devices out.
The reason is that because 2.4Ghz bands overlap, 2.4Ghz is usually very overcrowded with neighbour networks. 5Ghz allows a faster speed too depending on the specifications. The only drawback with 5Ghz is that its range is more limited than the 2.4Ghz, depending on the router.
The highest speed can be achieved on the 5GHz network by means of the AC-wifi standard. The 2.4GHz network has the best range. If you prefer, switching off 5GHz will reduce wifi radiation from the router even more.
Modifying or disabling the 5 GHz configuration, will not help with interference, within the 2.4 GHz frequency range. If you have 2.4 GHz performance problems, only changing the 2.4 GHz channel configuration, or reducing the interference that exists within that frequency range will help with that issue.
Will my phone and tablet switch automatically between the bands? It depends on your device. Older devices might not be able to connect to the newer 5GHz band at all, while others will flip seamlessly between them.
You have to make sure that your router is entirely up to date. So, due to outdated versions, many problems might occur on your device. The problem might also come from this reason if your router Firmware is not updated. In routers, manufacturers have the option of releasing updates for the device.
The 2.4 GHz Wi-Fi frequency band gives you more range and passes better through walls and other physical obstructions. The 5 GHz Wi-Fi frequency band provides more speed—a lot more. Using the latest Wi-Fi standard and the best router, 2.4 GHZ Wi-Fi can reach up to 600 Mbps under absolutely ideal conditions.
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.
So in summary making an SSID2. 4Ghz and an SSID5Ghz is usually a good idea. You can even use the QoS settings to just favor your 5Ghz SSID and keep that for your own computers and laptops. Then broadcast the use of 2.4G SSID for guests, tablets, kids devices, and all other lower need devices.
The advantage of a 2.4 GHz is that it has a farther range and it can penetrate solid objects better. However the disadvantage that it has, is that it's more vulnerable to interference. That's because so many other devices use the same band and it's also slower than the 5 GHz.
With these being just a few of the features coming with 802.11ax, it is clear that the 2.4 GHz band of wireless is not dead by any means. Utilizing these features will allow for this band of wireless to be revamped and more reliable in the modern business network environment.
Both 5GHz and 2.4GHz WiFi are 100% safe for humans, the signal does not harm health in any way. The term “radiation” is often used to scare people.
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.
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.
All smart products, despite the brand, only work with a 2.4 GHz signal. If your router sends out a 5 GHz signal, you probably get issues with connecting, as your smart device is only able to pick up the 2.4 GHz signal.
A high number of 2.4 GHz radios and overcrowding in the 2.4 GHz spectrum can degrade WLAN performance. WiFi doesn't work.
A simpler method is to move far enough away from your router (make sure to unplug the nearest mesh node); this might force your phone to connect to the 2.4-GHz band. Since this band has a better range, your smartphone will eventually switch from 5 GHz with enough distance.
Step 1 Click Advanced>Wireless>Wireless Settings. Step 2 Click 2.4GHz, and change Channel and Channel Width, then click Save. Step 3 Click 5GHz, and change Channel and Channel Width, then click Save. For 5GHz, we recommend you use channel in Band 4, which is channel 149-165, if your router supports it.
