Even if your router supports the fastest 5 GHz network, your device may not have the appropriate wireless network adapter. You can check if your computer can use this frequency more quickly by following the following tutorial.
The 2.4 GHz network is currently the standard used by most terminals for communication, which unfortunately also means that the frequency can be overloaded, resulting in lower Wifi speeds and a less stable connection.
As a solution, the 5Ghz frequency band has been introduced. The problem is that not all computers in this network can work and spend a little more on a router, just to have the 5Ghz network may be useless if your home devices can’t communicate with it.
Advantages of using a 5GHz Wi-Fi network
What are the main advantages of a 5 GHz Wi-Fi network? This frequency is less charged and less noisy. This is particularly important for people living in homes where many routers, telephones and microwave ovens in the vicinity operate at a frequency of 2.4 GHz. Operating at a higher frequency provides a larger bandwidth and supports 23 separate transmission channels (compared to three channels on a 2.4 GHz network). The disadvantage is the low coverage compared to 2.4 GHz.
November 2024 Update:
You can now prevent PC problems by using this tool, such as protecting you against file loss and malware. Additionally, it is a great way to optimize your computer for maximum performance. The program fixes common errors that might occur on Windows systems with ease - no need for hours of troubleshooting when you have the perfect solution at your fingertips:
- Step 1 : Download PC Repair & Optimizer Tool (Windows 10, 8, 7, XP, Vista – Microsoft Gold Certified).
- Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
- Step 3 : Click “Repair All” to fix all issues.
To determine the network capacity at 5GHz
- Locate “cmd” in the Start menu.
- Type “netsh wlan show drivers” at the command prompt and press Enter.
- Refer to the section “Supported functional cards”.
Determine the factor:
Locate the line that supports radio types.
- If the supported line types display 802.11g and 802.11n network modes, your laptop is only suitable for 2.4 GHz.
- If the supported line types display 802.11n, 802.11g and 802.11b network modes, your laptop is only suitable for 2.4 GHz.
- But if the supported radiotypes show network modes 802.11a and 802.11g and 802.11n, your laptop only has network capacities of 2.4 GHz and 5 GHz. This means that your laptop supports 5 GHz networking.
Using 5GHz Wi-Fi generally means a larger and faster web connection.
You can also learn more about the following aspects of your wireless connection:
- Identify drivers.
- Vendor.
- Provider.
- Date.
- Version.
- INF.
- Type.
- FIPS 140-2 mode assistant.
- Support for 802.11w management framework protection.
- Support from the host community.
- List of all supported authentications and encryptions in infrastructure mode.
However, these things can vary from one machine to another if you rely on the hardware and software aspects of the same.
What happens if the adapter does not support a 5 GHz network?
If your network adapter does not support 5 GHz Wi-Fi networks, simply use a 2.4 GHz network. If you want to work with the new frequency, purchase an external 5GHz USB Wi-Fi adapter (above, we have described the 802.11 network mode requirements that your device must meet).
