You can't change this on the iPhone, but your Wi-Fi router might have an option to assign separate names to the 2.4 GHz and 5 GHz networks. If your Wi-Fi router has this capability, you can simply connect the iPhone to either 2.4 GHz or 5 GHz signals by selecting the name of the network to which you want to connect.
From Notification Panel press and hold the WiFi icon until you enter WiFi settings screen. Select the network properties (tap the gear icon or menu icon). Depending on the Android version check: Read the “Frequency” setting – shows as 2.4 or 5GHz.
Tap and hold the Wi-Fi icon in the top-left corner. The name of your Wi-Fi access point appears below "Wi-Fi" on the left side of the panel. If you see either "2.4GHz" or "5GHz" here, you'll know that you're connected on that frequency.
Router settings: Access your router's administration interface and check if there is an option to separate the 2.4GHz and 5GHz networks. By disabling the network merging feature (sometimes called band steering or band aggregation), you can force your phone to connect to the 2.4GHz network.
Reset your Network Settings. Tap Settings > General > Reset > Reset Network Settings. This also resets Wi-Fi networks and passwords, cellular settings, and VPN and APN settings that you've used before." As previously mentioned, you do have the option of connecting with Apple Support for assistance at Get Support.
Restart the router
This is the primary step you should try first. Restarting the router device can fix many network-related problems that are happening to your device. So, this step might also solve the 2.4GHz Wi-Fi Not Working error.
Simultaneous dual-band routers are capable of receiving and transmitting on both 2.4 GHz and 5 GHz frequencies at the same time.
If you can't reach the login page, check if your router is acting up. Temporary issues with the router can be fixed with a quick restart. If that doesn't work, you can perform a factory reset to restore your router to its default settings. You can reset your router using the dedicated reset button or the web interface.
It's probably because the router firewall is enabled and prevents the other devices to connect to it. In this case you have to reset the router (by pushing the reset button with a pin or power off then power on after about 15 seconds). When the router comes up, you can access the admin page only for about one minute.
If you want better range, use 2.4 GHz. If you need higher performance or speed, use the 5GHz band. The 5GHz band, which is the newer of the two, has the potential to cut through network clutter and interference to maximize network performance. Which means this band will be better for things like reducing game lag.
2.4 GHz vs. 5 GHz: Which frequency should you choose? A 2.4 GHz connection travels farther at lower speeds, while 5 GHz frequencies provide faster speeds at shorter range. Your choice of 2.4 GHz or 5 GHz will depend on where and how you use your WiFi connection most.
SSID stands for Service Set IDentifier and is your network's name. If you open the list of Wi-Fi networks on your laptop or phone, you'll see a list of SSIDs. Wireless router or access points broadcast SSIDs so nearby devices can find and display any available networks.
What is a service set identifier (SSID)? A service set identifier (SSID) is a sequence of characters that uniquely names a Wi-Fi network. An SSID is sometimes referred to as a network name. This name allows stations to connect to the desired network when multiple independent networks operate in the same physical area.
No. What you want to do, is get as many devices setup using 5Ghz, and use the 2.4Ghz as a fall-back. 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.
Not really. The bands don't overlap and 5GHz has shorter range. One reason you might want to do it is if 2.4 is crowded with other people but you have 5GHz to yourself.
The 2.4 GHz band gives you slower speeds at a longer range, while the 5 GHz band gives you faster speeds at a shorter range. So, if you want the fastest WiFi speeds, you should always use the 5 GHz band. However, the more devices you have on one band, the slower your WiFi will be.
MANUALLY PAIRING 2.4 GHZ DONGLE TO THE KEYBOARD. Toggle the physical switch on the side of the keyboard to enter 2.4 GHz Mode. Press and hold FN + Enter for 5 seconds to enter pairing mode. The indicator & Enter key will rapidly flash BLUE 3 times one every second to confirm you are in Pairing Mode.
