The other day I bought a dual-band Wi-Fi router, it started to connect, etc. It seems to have two networks, one 2.4 GHz, the other 5 GHz. My computer and mobile devices cannot see a 5 GHz router, they only see 2.4 GHz.
As if in the search for Wi-Fi, Devices and PCs see only Tp_Link_0D34 (2.4 GHz), but Tp_Link_0D34_5G (5 GHz) do not.
Answer
That your router is really dual-band, I think, there can be no doubt. Although, it would be nice to know the model of the router and, in general, describe your question in more detail. Especially write the models of devices that do not see the network in the 5 GHz range and the model of the Wi-Fi adapter on the PC.
Usually, in such situations, there are two reasons:
- Something with the router settings. You may have accidentally turned off the 5 GHz network during the setup process. You need to look in the settings, it is possible to change the network name (SSID) and the channel on which this network works. It is best to do a factory reset on your router. Also, pay attention to the indicators that are on the router. I don't know what kind of router you have, but usually there are two Wi-Fi indicators: one for the 5 GHz network and the other for the 2.4 GHz network.
- The second reason, the most popular, is that devices that cannot see the network in the 5 GHz band do not support this band. Perhaps a Wi-Fi adapter on your computer does not support Wi-Fi 5 GHz. Here I could tell you in more detail if I knew the models of your mobile devices and the adapter itself, which is connected to the PC. Whether Wi-Fi 5 GHz is supported or not, you can easily find out by looking at the specifications. Wi-Fi 802.11ac support is usually indicated. If the device supports this standard, then it should see networks in the 5 GHz range.
I already wrote about this in a separate article: why a laptop, smartphone, or tablet does not see a 5 GHz Wi-Fi network.
