![[Solved] PC does not see 5GHz WiFi but only 2.4GHz? -](/images/logo.png){kind=logo}
If you have replaced or bought a new router then you may come across terms like "dual band“, A term that refers to a router that uses two frequencies: 2,4 GHz Wi-Fi and 5 GHz. What do they mean and what is the real one difference between 2,4Ghz and 5GHz?
These numbers refer to two different “bands” that your Wi-Fi can use to send its signal. The biggest difference between the two signals is the speed. In ideal conditions, 2,4GHz Wi-Fi will support up to 450Mbps or 600Mbps, depending on the class of the router. 5GHz Wi-Fi will support up to 1300Mbps.
Of course, there are some things to know about it. First, the maximum speed you might see also depends on the wireless standard a router supports: 802.11b, 802.11g, 802.11n, or 802.11ac.
The other important thing to know is the meaning of that important word we mentioned: "ideal conditions". There 2,4 GHz band it is quite a busy place, as it is used by more than just Wi-Fi. Older cordless phones, garage door openers, baby monitors, and other devices tend to use the 2,4GHz band. The longer waves used by the 2,4GHz band are better suited to longer distances and transmission through walls and solid objects. So it's probably that bandwidth is best if you need better range on your devices or have a lot of walls or other objects in areas where you need coverage. However, because so many devices use the 2,4GHz band, the resulting congestion can cause dropped connections and slower-than-expected speeds.
La 5 GHz band it's much less congested, which means you'll likely get more stable connections. You will also see higher speeds. On the other hand, the shorter waves used by the 5 GHz band are less able to penetrate walls and solid objects. It also has a shorter range than the 2,4 GHz band. Of course, you may also be able to mitigate that shorter range through the use of range extenders or Wi-Fi mesh systems, but that will involve an investment. greater.
Why does my PC not see 5GHz WiFi but only 2.4GHz?
The above question is very frequent. Many after connecting their modem (with two bandwidths, 2,4GHz and 5GHz) notice that their computer only connects to 2,4 GHz.
This problem could be caused by the driver. Before continuing, it is advisable to update the drivers of your PC. If you don't have the time, patience, or computer skills to update your computer's drivers manually, you can do it automatically with Driver Easy. At the following link you will find a detailed guide: how to update pc driver
The other cause could be that your computer does not support 5 GHz bandwidth. You can check this by following the steps below.
1. Click on the menu Home.
2. Press the Windows key and R (at the same time). A window with a text box will appear.
3. Type cmd in the box and click OK.
4. In the "command prompt" window that will open, type the command "netsh wlan show drivers". Hit enter.

If it says the network card supports network modes 802.11g e 802.11n, it means the computer only has 2,4GHz network capability.
If it says the adapter supports network modes 802.11a e 802.11g e 802.11n, it means the computer has 2,4GHz and 5GHz network capacity.
If it indicates 802.11n 802.11g and 802.11b network modes, it means the computer only has 2,4GHz network capability.
Since I put the Vodafone fiber on my desktop no longer connects to the Internet. With linkem it went …… Help. Thanks
hello everyone my computer that previously connected to the 5g of the extender, now, after the summer, it only connects to the 2.4g, (only that option appears in the wifi of the computer even if the extender always transmits at 5g, as confirmed by the cell phone network, which instead normally goes to 5g, I repeat before the summer the computer was also connected to 5.g, possible that in two months ...?
hi my fixed pc 802.11n 802.11g 802.11b so it does not go with 5ghz, but the modem uses the frequency of 2.4ghz 5ghz and 2.45 ghz should I use the 2.45 ghz? for mobile phones that support 5ghz, but could it affect the establishment of the pc connection? because I see that it goes up and down a notch. Thank you

No, it cannot affect the connection stability of the PC
I checked and my computer holds both 2.4ghz and 5ghz but when I use it the computer only uses 2.4ghz how could I do to put 5ghz?
I had made a mistake in typing the command. I checked the supported network modes, They are: 802.11n 802.11g and 802.11b, it means the computer only has 2,4GHz network capability. But since my router is dual band, the pc shouldn't auto connect always to the 2.4 network? As I wrote above, it occasionally connects for a few minutes and then disconnects from the network. If I try to reconnect I can't do it .. basically it decides for itself when to do it.
Hi, by running the above command the black screen disappears in half a second. I cannot read the supported types. Anyway, let's say my card doesn't support 5gh (it's a Broadcom 802.11n network card, with drivers updated to 2013 and there are no others, all mounted on a 6 hp dv2010 laptop). So I ask, can I go into my router settings and set the connection to only 2.4 gh? Now I am connected with a network shared by my 2,4 gh smartphone, I had also tried with 5 gh but the computer could not read the network.
NB
I have done all the tests in this world, including uninstalling, enabling, updating etc .. but those few times that the pc manages to connect after a few minutes it loses the connection, so I assume that the card is not broken, since now I am connected with sharing my mobile for a few hours.
When the PC, like my case, does not support 5G, is there no way to do anything but change the "machine"?

Hi Mariano, you have several possibilities, it depends on the PC, if it is a laptop (and by following the advice above you can't solve it) you can look for a usb "dongle" and add a second wifi card, if it is a fixed pc ... actually same solution, but it could also be an internal card (I don't recommend it….). Of course you need to make sure that the dongle / card you buy is 5G compatible

Hi, I have a portable emachines E440 a FTTH fiber line with 2 lines 2.4 and 5G ..
MY laptop does not find the 5G network but only the 2.4 .. Reading in the settings it has a frequency of 2.2 up to 2.6 .. How can I do as long as my laptop can connect to the 5G network ??? Do I have to change the motherboard because it doesn't support 5G ???
Or do you have a better tip to simply connect to 5G without spending a lot of money on expensive add-ons?
I forgot to use the laptop near the modem, 4/5 meters away in open space ..
Thank you very much for your availability, I hope to resolve I'm desperate because I work for a call center in smartworking and customers feel very robotic, sometimes they don't even hear me or very, very far away ..
Which is faster .. the 2.4GHZ or 5GHZ?
-
In theory, 5GHZ is faster. However, we must consider that 5GHZ is a "weaker" signal because it is easily filtered if there are walls or obstacles.
