2,4hz not working on AX201

[Kasia]

Hi,

Few days ago i've got new laptop and i can't connect with 2,4hz band, 5hz band from the same router works ok. I've already tried updating drivers (has newest version) and resetting it too. 

My biggest problem is that my router doesn't work on both bands at the same time, and my few other devices only work on 2,4hz. so i either don't have connection on laptop or on other devices.

Some specs:
Lenovo Legion 5i with i5 CPU
Intel(R) Wi-Fi 6 AX201 160MHz
driver ver: 22.40.0.7

Windows 10 Home 64bit ver. 20H2

I use mobile router alcatel 4G LTE Cat7 Mobile WiFi.

Is there any solution for this? Or should i just change wifi adapter?

PS. I'm little bit of tech boomer, please be patient with me

Kasia,

Sadly, there are instances where devices will not connect properly on 2.4 GHz wireless. I know of at least two instances where a laptop or smart device didn't even list the 2.4 GHz network as something to connect to. It is as if the devices just don't receive the wireless signal, while other devices work just fine.

I don't have the setup guide for the 4G LTE Cat7 Mobile WiFi. What could work is to get a wireless router and connect it via the USB cable to the Mobile WiFi. That way the 4G LTE Cat7 Mobile WiFi would still be the Internet service, but the router could handle the wireless connections. You will need to determine if the USB port on the 4G LTE Cat7 Mobile WiFi allows an Ethernet type connection. And if yes, then you need a router that can connect via USB for Internet. The thing to keep in mind is the cost for all that. It might just be cheaper to get a different mobile WiFi unit that supports both2.4 GHz and 5 GHz simultaneously.
