Most routers are dual band models. This means that they work with 2.4GHz and 5GHz Wi-Fi. While 2.4 GHz is even more reliable over longer doors, and passes through walls and floors, 5 GHz can offer much higher speeds.
Does my router work with 5GHz?
unless you are already certain that your router is a dual band model and that it supports the 5GHz band, then we advise you to check it. Indeed, it is useless to activate 5GHz Wi-Fi on your laptop if your router does not support it.
The easiest way is to consult the manual or connect to the router, then check the parameters available in the Wi-Fi section. Note that some routers have the same SSID (network name) for 2.4 and 5GHz.
It is therefore advisable to divide them into two separate Wi-Fi networks if such an option is available. You can easily identify each network from your PC, but also your phone or tablet, and know which one you are connected to.
How do you know if your laptop can use the 5GHz Wi-Fi band?
The best way to find out is to open the Control panel, to go in Devices and printers Device manager, then find the brand and model of your computer's Wi-Fi in the section Network Cards.
This laptop, for example, is equipped with a Qualcomm Atheros AR9285 adapter. Searching online for this brand and model gives many results for its specifications. These show that it only works at 2.4 GHz.
If your network card is compatible with the 802.11a standard, then it will certainly be compatible with the 5GHz standard. The same goes for 802.11ac.
You can also take the path given above, then click on the tab Forward. You will see a list of properties, one of which should mention 5GHz.
If you don't see an option to enable or disable 5 GHz, then either your network card does not support it, or the wrong drivers are installed.
Activate 5GHz on a laptop
If you really want to use 5GHz because you have too many 2.4GHz networks, then get a USB Wi-Fi key. These dongles are inexpensive, from 6 to 30, and allow you to upgrade your PC without even having to open it.
